Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business Organization	NOTE 1 — BUSINESS ORGANIZATION Description of Business Carvana Co. and its wholly-owned subsidiary Carvana Co. Sub (collectively, "Carvana Co.") together with its consolidated subsidiaries (the "Company") is a leading e-commerce platform for buying and selling used cars. The Company is transforming the used car sales experience by giving consumers what they want - a wide selection, great value and quality, transparent pricing and a simple, no pressure transaction. Using the website, customers can complete all phases of a used vehicle purchase transaction including financing their purchase, trading in their current vehicle and purchasing complementary products such as vehicle service contracts and GAP waiver coverage. Each element of the Company's business, from inventory procurement to fulfillment and overall ease of the online transaction, has been built for this singular purpose. Organization and Initial Public Offering Carvana Co. is a holding company that was formed as a Delaware corporation on November 29, 2016, for the purpose of completing an initial public offering ("IPO") and related transactions in order to operate the business of Carvana Group, LLC and its subsidiaries (collectively, "Carvana Group"). Substantially all of the Company’s assets and liabilities represent the assets and liabilities of Carvana Group, except the Company's senior unsecured notes which were issued by Carvana Co. and guaranteed by its and Carvana Group's existing domestic restricted subsidiaries. Carvana Group was formed as a limited liability company by DriveTime Automotive Group, Inc. (together with its subsidiaries and affiliates "DriveTime") and commenced operations in 2012. Prior to November 1, 2014, Carvana Group was a wholly-owned subsidiary of DriveTime. On November 1, 2014 (the "Distribution Date"), DriveTime distributed its member units in Carvana Group to the unit holders of DriveTime on a pro rata basis (the "Distribution"). Carvana Group accounted for the Distribution as a spinoff transaction in accordance with ASC 505-60, Equity - Spinoffs and Reverse Spinoffs and reflected assets and liabilities before and after the Distribution Date at their historical basis. On May 3, 2017, Carvana Co. completed its IPO of 15.0 million shares of Class A common stock at a public offering price of $15.00 per share. Carvana Co. received approximately $205.8 million in proceeds, net of underwriting discounts and commissions and offering expenses, which it used to purchase approximately 18.8 million newly-issued membership interests of Carvana Group at a price per unit equal to 0.8 times the initial public offering price less underwriting discounts and commissions and offering expenses. Also in connection with the IPO, the Company completed the following organizational transactions (the "Organizational Transactions"): • Carvana Group amended and restated its limited liability company operating agreement (the "LLC Agreement") to, among other things, (i) eliminate a class of preferred membership interests, (ii) provide for two classes of common ownership interests in Carvana Group held by the then-existing holders of LLC units (the "Original LLC Unitholders" and together with any holders of LLC units issued subsequent to the IPO, the "LLC Unitholders") consisting of Class B common units (the "Class B Units") and Class A common units (the "Class A Units"), and (iii) appoint Carvana Co. as the sole manager of Carvana Group; • Carvana Co. amended and restated its certificate of incorporation to authorize (i) 50.0 million shares of Preferred Stock, par value $0.01 per share, (ii) 500.0 million shares of Class A common stock, par value $0.001 per share, and (iii) 125.0 million shares of Class B common stock, par value $0.001 per share. Each share of Class A common stock generally entitles its holder to one vote on all matters to be voted on by stockholders. Each share of Class B common stock held by Ernest Garcia II, Ernest Garcia III and entities controlled by one or both of them (collectively, the "Garcia Parties") generally entitles its holder to ten votes on all matters to be voted on by stockholders. All other shares of Class B common stock generally entitle their holders to one vote per share on all matters to be voted on by stockholders; • Carvana Group converted its outstanding Class C Redeemable Preferred Units into approximately 43.1 million Class A Units; • Carvana Co. issued approximately 117.2 million shares of Class B common stock to holders of Class A Units, on a four-to-five basis with the number of Class A Units they owned, for nominal consideration; and, • Carvana Co. transferred approximately 0.2 million Class A Units to Ernest Garcia II in exchange for his 0.1% ownership interest in Carvana, LLC, a majority-owned subsidiary of Carvana Group. In accordance with the LLC Agreement, Carvana Co. has all management powers over the business and affairs of Carvana Group and conducts, directs and exercises full control over the activities of Carvana Group. Class A Units and Class B Units (the "LLC Units") do not hold voting rights, which results in Carvana Group being considered a variable interest entity ("VIE"). Due to Carvana Co.'s power to control and its significant economic interest in Carvana Group, it is considered the primary beneficiary of the VIE and the Company consolidates the financial results of Carvana Group. As of December 31, 2018, Carvana Co. owned approximately 27.2% of Carvana Group and the LLC Unitholders owned the remaining 72.8%. The Organizational Transactions described above are considered transactions between entities under common control. As a result, the financial statements for periods prior to the IPO and Organizational Transactions have been adjusted to combine the previously separate entities for presentation purposes. Follow-On Public Offering On April 30, 2018, the Company completed a follow-on offering of 6.6 million shares of its Class A common stock at a public offering price of $27.50 per share and received net proceeds from the offering of approximately $172.3 million after underwriting discounts and commissions and offering expenses. The Company used the net proceeds to purchase approximately 8.3 million newly-issued LLC Units in Carvana Group, which used the net proceeds primarily for general corporate purposes. A holder of Class A common stock (the "Selling Stockholder") and certain LLC Unitholders (the "Selling LLC Unitholders") sold a total of approximately 6.1 million shares of Class A common stock as part of the offering. The Selling LLC Unitholders exchanged approximately 6.9 million LLC Units for approximately 5.6 million shares of Class A common stock to be sold in the offering, and to the extent such Selling LLC Unitholder held Class B common stock, the corresponding shares of Class B common stock were immediately retired by the Company. The Company did not receive any proceeds from the sale of the approximately 6.1 million shares of Class A common stock by the Selling Stockholder and the Selling LLC Unitholders. Convertible Preferred Stock On December 5, 2017, Carvana Co. amended and restated its certificate of incorporation to authorize 100,000 shares of Class A Convertible Preferred Stock, with an initial stated value of $1,000 per share and a par value of $0.01 per share (the "Convertible Preferred Stock") and, effective December 5, 2017, Carvana Group amended its LLC Agreement to, among other things, create a class of convertible preferred units. On December 5, 2017, Carvana Co. sold 100,000 shares of Convertible Preferred Stock for net proceeds of approximately $98.5 million, which it used to purchase 100,000 newly-issued convertible preferred units of Carvana Group (the "Convertible Preferred Units") at a price per unit equal to the initial stated value of the Convertible Preferred Stock less issuance costs. During the year ended December 31, 2018, all 100,000 shares of Convertible Preferred Stock were converted into approximately 5.1 million shares of Class A common stock. Simultaneously, and in connection with these conversions, Carvana Group converted Carvana Co.'s 100,000 Convertible Preferred Units into approximately 6.3 million Class A Units.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). All intercompany balances and transactions have been eliminated. As discussed in Note 1 — Business Organization, Carvana Group is considered a VIE and Carvana Co. consolidates its financial results due to the determination that it is the primary beneficiary. The Company reviews subsidiaries and affiliates, as well as other entities, to determine if they should be considered variable interest entities, and whether it should change the consolidation determinations based on changes in their characteristics. The Company considers an entity a VIE if its equity investors own an interest therein that lacks the characteristics of a controlling financial interest or if such investors do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support or if the entity is structured with non-substantive voting interests. To determine whether or not the entity is consolidated with the Company’s results, the Company also evaluates which interests are variable interests in the VIE and which party is the primary beneficiary of the VIE. Liquidity The accompanying consolidated financial statements of the Company have been prepared in conformity with U.S. GAAP, which contemplate continuation of the Company as a going concern. The Company has incurred losses each year from inception through December 31, 2018, and expects to incur additional losses in the future. As the Company continues to grow into new markets, build vending machines and inspection and reconditioning centers and enhance technology and software development efforts, it needs access to substantial capital. From inception, the Company has primarily funded operations through the sale of Class A Units, the sale of Class C Redeemable Preferred Units, capital contributions from DriveTime, its IPO completed on May 3, 2017, for net proceeds of approximately $205.8 million, its follow-on offering completed on April 30, 2018, for net proceeds of approximately $172.3 million, its issuance of Class A Convertible Preferred Stock on December 5, 2017, for net proceeds of approximately $98.5 million, and the issuance of senior unsecured notes for net proceeds of approximately $342.5 million on September 21, 2018. The Company has historically funded vehicle inventory purchases through its Floor Plan Facility and had approximately $453.0 million available under its $650.0 million Floor Plan Facility that matures in October 2020 to fund future vehicle inventory purchases as of December 31, 2018, as described further in Note 8 — Debt Instruments. Further, the Company plans to increase the amount and maturity date of financing available to purchase vehicle inventory within the next year by amending its existing Floor Plan Facility or by entering into a new agreement. The Company has also funded some of its capital expenditures through long-term financing with lenders and other investors as described in further detail in Note 8 — Debt Instruments. The Company has historically entered into various agreements under which it sells the finance receivables it originates to financing partners. As of December 31, 2018, the Company sells finance receivables under multiple agreements, as described in further detail in Note 7 — Finance Receivable Sale Agreements, that expire in November 2019, subject to each party's rights under the respective agreement. The Company plans to extend or enter into new agreements to sell its finance receivables to financing partners within the next year. Management believes that current working capital and expected continued inventory and capital expenditure financing is sufficient to fund operations for at least one year from the financial statement issuance date. Use of Estimates The preparation of these consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. Certain accounting estimates involve significant judgments, assumptions and estimates by management that have a material impact on the carrying value of certain assets and liabilities, disclosures of contingent assets and liabilities and the reported amounts of revenues and expenses during the reporting period, which management considers to be critical accounting estimates. The judgments, assumptions and estimates used by management are based on historical experience, management’s experience and other factors, which are believed to be reasonable under the circumstances. Because of the nature of the judgments and assumptions made by management, actual results could differ materially from these judgments and estimates, which could have a material impact on the carrying values of the Company’s assets and liabilities and the results of operations. Comprehensive Loss During the years ended December 31, 2018, 2017 and 2016, the Company did not have any other comprehensive income and, therefore, the net loss and comprehensive loss were the same for all periods presented. Cash and Cash Equivalents The Company has cash deposits and cash equivalents deposited in or managed by major financial institutions. Cash equivalents include highly liquid investment instruments with original maturities of three months or less, and consist primarily of money market funds. At times the related amounts are in excess of the amounts insured by the Federal Deposit Insurance Corporation. The Company has not experienced any losses with these financial institutions and does not believe it represents significant credit risk. Restricted Cash The restricted cash includes the deposit required under the Company's Floor Plan Facility, which is 5% of the outstanding floor plan facility principal balance, as explained in Note 8 — Debt Instruments and, in previous periods, amounts held as restricted cash as required under letter of credit agreements, as explained in Note 14 — Commitments and Contingencies. Accounts Receivable, Net Accounts receivable, net of an allowance for doubtful accounts, includes certain amounts due from customers and their finance providers. The allowance for doubtful accounts is estimated based upon historical experience, current economic conditions and other factors and is evaluated periodically. The allowance for doubtful accounts was approximately $0.4 million as of both December 31, 2018 and 2017. Finance Receivables Held for Sale, Net Finance receivables include installment contracts the Company originates to its customers to facilitate vehicle sales. The Company classifies these receivables as held for sale, as it does not intend to hold the finance receivables it originates to maturity. The Company typically sells the finance receivables it originates, as explained in Note 7 — Finance Receivable Sale Agreements. The Company records a valuation allowance to report finance receivables at the lower of unpaid principal balance or fair value. To determine the fair value of finance receivables the Company utilizes industry-standard modeling, such as discounted cash flow analysis, factoring in the Company’s historical experience, the credit quality of the underlying receivables, loss trends and recovery rates, as well as the overall economic environment. For purposes of determining the valuation allowance, finance receivables are evaluated collectively to determine the allowance as they represent a large group of smaller-balance homogeneous loans. The allowance was approximately $1.8 million and $0.9 million as of December 31, 2018 and 2017, respectively. Principal balances of finance receivables are charged-off when the Company is unable to sell the finance receivable and the related vehicle has been repossessed and liquidated or the receivable has otherwise been deemed uncollectible. The Company has made certain representations related to the sales of finance receivables. Any significant estimated post-sale obligations or contingent obligations to the purchaser of the receivables would be accrued if probable and estimable in accordance with ASC 450, Contingencies . Any such obligations are considered in the Company's determination of the accounting for the transfers of the finance receivables under ASC Topic 860, Transfers and Servicing of Financial Assets. Vehicle Inventory Vehicle inventory consists of used vehicles, primarily acquired at auction. Direct and indirect vehicle reconditioning costs including parts and labor, inbound transportation costs and other incremental overhead costs are capitalized as a component of inventory. Inventory is stated at the lower of cost or net realizable value. Vehicle inventory cost is determined by specific identification. Net realizable value is the estimated selling price less costs to complete, dispose and transport the vehicles. Selling prices are derived from historical data and trends, such as sales price and inventory turn times of similar vehicles, as well as independent market resources. Each reporting period the Company recognizes any necessary adjustments to reflect vehicle inventory at the lower of cost or net realizable value through cost of sales in the accompanying consolidated statements of operations. Property and Equipment Property and equipment consists of land, buildings and improvements, transportation fleet equipment, software and furniture, fixtures and equipment and is stated at cost less accumulated depreciation and amortization. Repairs and maintenance costs that extend the life or utility of an asset are also capitalized. Ordinary repairs and maintenance are charged to expense as incurred. Costs incurred during construction are capitalized as construction in progress and reclassified to the appropriate fixed asset categories when the project is completed. In addition, interest on borrowings during the active construction period of construction projects is capitalized and depreciated over the estimated useful lives of the related assets. Costs incurred during the preliminary project planning phase are charged to expense as incurred. The Company capitalizes direct costs of materials and services consumed in developing or obtaining internal-use software. The Company also capitalizes payroll and payroll-related costs for employees who are directly associated with and who devote time to the development of software products for internal use, to the extent of the time spent directly on the project. Capitalization of costs begins during the application development stage and ends when the software is available for general use. Costs incurred during the preliminary project and post-implementation stages are charged to expense as incurred. Depreciation and amortization are computed using the straight-line method over the lesser of the remaining lease term or the following estimated useful lives: Buildings and improvements 5-30 years Transportation fleet equipment 3-8 years Software 3 years Furniture, fixtures and equipment 3-5 years Management reviews long-lived assets for impairment when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. The Company compares the sum of estimated undiscounted future cash flows expected to result from the use of the asset to the carrying value of the asset. When the carrying value of the asset exceeds its estimated undiscounted future cash flows, the Company recognizes an impairment charge for the amount by the which the carrying value of the asset exceeds the fair value of the asset. The Company recorded no impairment charges during the years ended December 31, 2018, 2017 and 2016. See Note 3 — Property and Equipment, Net for additional information on property and equipment. Goodwill and Intangible Assets Intangible assets are recognized and recorded at their acquisition date fair values. Definite-lived intangible assets consist of developed technology, customer relationships and non-compete agreements and are amortized on a straight-line basis over their estimated useful lives . The Company determined the useful lives of its definite-lived intangible assets based on multiple factors including technological obsolescence, the make-up of the acquired customer base and expected attrition, and the period over which expected cash flows are used to measure the fair value of the intangible asset at acquisition. The Company periodically reassesses the useful lives of its definite-lived intangible assets when events or circumstances indicate that useful lives have significantly changed from the previous estimate. Definite-lived intangible assets are tested at least annually or more frequently when events or changes in circumstances indicate that the carrying value may not be recoverable. No impairment charges related to intangible assets were recognized during the years ended December 31, 2018, 2017 or 2016. Goodwill represents the excess purchase price over the fair value of the net assets acquired. Goodwill is not amortized but is tested at least annually or more frequently when events or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company has one operating segment, which is its reporting unit; therefore, management analyzes goodwill associated with all of its operations when analyzing for potential impairment. The Company first assesses qualitative factors to determine if it is not more likely than not that the fair value of its reporting unit is less than its carrying amount. No impairment charges related to goodwill were recognized during the years ended December 31, 2018, 2017 or 2016. Finance Leases The Company finances certain purchases and construction of its property and equipment through various sale-and-leaseback transactions that do not qualify for sale accounting due to forms of continuing involvement. Accordingly, the Company records the assets subject to these transactions within property and equipment and the sales proceeds as finance leases within long-term debt in the accompanying consolidated balance sheets. Required monthly payments, less the portion considered to be interest expense, reduce the corresponding liabilities. See Note 8 — Debt Instruments for additional information on finance leases. Other Current Assets Other current assets consist of various items, including, among other items, software licenses and subscriptions, prepaid expenses, debt issuance costs on revolving debt instruments, deposits and commitment fees related to the Company's finance receivable sale agreements. As further discussed below, in connection with adopting ASC 606, Revenue from Contracts with Customers , beginning on January 1, 2018, other current assets also includes the reserve for estimated vehicle inventory returns. Other Assets Other assets consist of various items, including, among other items, the purchase price adjustment receivable based on the performance of the Company's finance receivables, the receivable related to the excess cash reserves over realized claims of VSCs, deposits and debt issuance costs on revolving debt instruments. Accrued Liabilities Accrued liabilities consist of various items payable within one year, including, among other items, accruals for capital expenditures, sales tax, compensation and benefits, vehicle licenses and fees, interest expense and advertising expenses. Other Liabilities Other liabilities consist of various items payable beyond one year, including, among other items, the long-term portion of deferred rent. Other liabilities also include items to be recognized beyond one year, including the long-term portion of the tenant improvement allowance associated with the Company's corporate headquarters and the deferred tax liability associated with acquisitions of intangible assets. Revenue Recognition The Company adopted ASC 606, Revenue from Contracts with Customers on January 1, 2018 using the modified retrospective method. ASC 606 prescribes a five-step model that includes: (1) identify the contract; (2) identify the performance obligations; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations; and (5) recognize revenue when (or as) performance obligations are satisfied. Based on the manner in which the Company historically recognized revenue, the adoption of ASC 606 did not have a material impact on the amount or timing of its revenue recognition and the Company recognized no cumulative effect adjustment upon adoption. Used Vehicle Sales The Company sells used vehicles directly to its customers through its website. The prices of used vehicles are set forth in the customer contracts at stand-alone selling prices which are agreed upon prior to delivery. The Company satisfies its performance obligation for used vehicle sales upon delivery when the transfer of title, risks and rewards of ownership and control pass to the customer. The Company recognizes revenue at the agreed upon purchase price stated in the contract, including any delivery charges, less an estimate for returns. Estimates for returns are based on an analysis of historical experience, trends and sales data. Changes in these estimates are reflected as an adjustment to revenue in the period identified. The amount of consideration received for used vehicle sales includes noncash consideration representing the value of trade-in vehicles, if applicable, as stated in the contract. Prior to the delivery of the vehicle, the payment is received or financing has been arranged. Payments from customers that finance their purchases with third parties are typically due and collected within 30 days of delivery of the used vehicle. Revenue excludes any sales taxes, title and registration fees, and other government fees that are collected from customers. Wholesale Vehicle Sales The Company sells vehicles to wholesalers. These vehicles sold to wholesalers are primarily acquired from customers that do not meet the Company’s quality standards to list and sell through its website. The Company satisfies its performance obligation for wholesale vehicle sales when the wholesale purchaser obtains control of the underlying vehicle, which is upon delivery when the transfer of title, risks and rewards of ownership and control pass to the customer. The Company recognizes revenue at the amount it expects to receive for the used vehicle, which is the fixed price determined at the auction. The purchase price of the wholesale vehicle is typically due and collected within 30 days of delivery of the wholesale vehicle. Other Sales and Revenues Other sales and revenues include gains on the sales of finance receivables, commissions on vehicle service contracts ("VSCs"), GAP waiver coverage, and interest income received on finance receivables prior to selling them to investors. Customers purchasing used vehicles from the Company may enter into contracts for VSCs. The Company sells and receives a commission on VSCs under a master dealer agreement with DriveTime, pursuant to which the Company sells VSCs that DriveTime administers and is the obligor. The Company recognizes commission revenue at the time of sale, net of a reserve for estimated contract cancellations. The reserve for cancellations is estimated based upon historical experience and recent trends and is reflected as a reduction of other sales and revenues. Changes in these estimates are reflected as an adjustment to revenue in the period identified. Under the master dealer agreement with DriveTime, the Company is also contractually entitled to receive profit-sharing revenues based on the performance of the VSCs once a required claims period has passed. This is a form of variable consideration the Company recognizes as revenue to the extent that it is probable that it will not result in a significant revenue reversal. The Company applies the expected value method, utilizing expected VSC performance based on historical claims and cancellation data from its customers, as well as other qualitative assumptions to estimate the amount it expects to receive. The Company reassess the estimate each reporting period with any changes reflected as an adjustment to other sales and revenues in the period identified. Profit-sharing payments will begin when the underlying VSCs reach a specified level of claims history. As of December 31, 2018, the Company had recognized approximately $1.9 million related to cumulative profit-sharing payments to which it expects to be entitled, which is included in other assets on the accompanying consolidated balance sheet. Customers that finance their used vehicle purchases with the Company may enter into contracts to purchase GAP waiver coverage, which obligates whoever holds the underlying finance receivable to not attempt collection of a balance that is in excess of the value of the financed vehicle in the event of a total loss. The price of GAP waiver coverage is set forth in each contract. GAP waiver coverage is recognized as the performance obligation is satisfied over the period of coverage, generally on a straight-line basis over the expected period the outstanding balance of the related finance receivable will exceed the value of the financed vehicle, less a reserve for cancellations. The reserve for cancellations is estimated based upon historical experience and recent trends and is reflected as a reduction of other sales and revenues. Changes in these estimates are reflected as an adjustment to other sales and revenues in the period identified. Upon selling the corresponding finance receivable, the Company recognizes any remaining deferred revenue. DriveTime administers a portion of the GAP waiver coverage contracts the Company sells to its customers. The Company also periodically arranges refinancing for its financing partners and earns a fee for structuring and participating the transaction, which it recognizes upon completion. The Company accounts for sales of finance receivables in accordance with ASC Topic 860, Transfers and Servicing of Financial Assets ("ASC 860"). ASC 860 states that a transfer of an entire financial asset, a group of entire financial assets, or a participating interest in an entire financial asset in which the transferor surrenders control over those financial assets is accounted for as a sale only if all of the following conditions are met: • The transferred financial assets have been isolated from the transferor - put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership. • Each transferee has the right to pledge or exchange the assets (or beneficial interests) it received, and no condition both constrains the transferee (or third-party holder of its beneficial interests) from taking advantage of its right to pledge or exchange the asset and provides more than a trivial benefit to the transferor. • The transferor, its consolidated affiliates included in the financial statements being presented or its agents do not maintain effective control over the transferred financial assets or third-party beneficial interests related to those transferred assets. For the years ended December 31, 2018, 2017 and 2016, all transfers of finance receivables met the requirements for sale treatment. The Company records the gain on the sale of a finance receivable upon cash receipt, in an amount equal to the net proceeds received less the carrying amount of the finance receivable. Cost of Sales Cost of sales includes the cost to acquire used vehicles and direct and indirect vehicle reconditioning costs associated with preparing the vehicles for resale. Vehicle reconditioning costs include parts, labor, inbound transportation costs and other incremental overhead costs, which are allocated to inventory via specific identification and standard costing. Occupancy and labor costs not related to vehicle acquisition or reconditioning, including those incurred in connection with expanding production capacity, are expensed as incurred as a component of selling, general and administrative expense. Cost of sales also includes any necessary adjustments to reflect vehicle inventory at the lower of cost or net realizable value. Selling, General and Administrative Expenses Selling, general and administrative ("SG&A") expenses primarily include compensation and benefits, advertising, depreciation expense, facilities costs, technology expenses, logistics and fulfillment expenses and other administrative expenses. SG&A expenses exclude the costs related to reconditioning vehicles and inbound transportation, which are included in cost of sales, and payroll costs of employees related to the development of software products for internal use, which are capitalized to software and depreciated over the estimated useful lives of the related assets. Advertising Costs Advertising production costs are expensed the first time the advertising takes place. All other advertising costs are expensed as incurred. Advertising expenses are included in SG&A expenses on the accompanying consolidated statements of operations. Advertising expense was approximately $111.2 million, $55.7 million and $27.0 million during the years ended December 31, 2018, 2017 and 2016, respectively. Equity-Based Compensation The Company classifies equity-based awards granted in exchange for services as either equity awards or liability awards. The classification of an award as either an equity award or a liability award is generally based upon cash settlement options. Equity awards are measured based on the fair value of the award at the grant date. Liability awards are re-measured to fair value each reporting period. Each reporting period, the Company recognizes the change in fair value of awards issued to non-employees as expense. The Company recognizes equity-based compensation on a straight-line basis over the award’s requisite service period, which is generally the vesting period of the award, less actual forfeitures. No compensation expense is recognized for awards for which participants do not render the requisite services. For equity and liability awards earned based on performance or upon occurrence of a contingent event, when and if the awards will be earned is estimated. If an award is not considered probable of being earned, no amount of equity-based compensation is recognized. If the award is deemed probable of being earned, related compensation expense is recorded over the estimated service period. To the extent the estimate of awards considered probable of being earned changes, the amount of equity-based compensation recognized will also change. See Note 11 — Equity-Based Compensation for additional information on equity-based compensation. Shipping and Handling The Company's logistics costs related to transporting its used vehicle inventory include fuel, maintenance and depreciation related to operating its own transportation fleet and third party transportation fees. The portion of these costs related to inbound transportation from the point of acquisition to the inspection and reconditioning center is included in cost of sales when the related used vehicle is sold. Logistics costs not included in cost of sales are included in selling, general and administrative expenses in the accompanying consolidated statements of operations and were approximately $35.2 million, $14.4 million and $8.4 million during the years ended December 31, 2018, 2017 and 2016, respectively, excluding compensation and benefits. Defined Contribution Plan The Company sponsors a qualified 401(k) retirement plan (defined contribution plan) for its employees. The plan covers substantially all employees who have attained the age of 18. Participants may voluntarily contribute to the plan up to the maximum limits established by Internal Revenue Service regulations. The Company provides matching contributions of 40% up to the first 6% of an employee’s compensation, which vests evenly over the employee’s initial five Employer contributions to the plan, net of forfeitures, were approximately $1.1 million, $0.7 million and $0.3 million for the years ended December 31, 2018, 2017 and 2016, respectively. Employer contributions are included in selling, general and administrative expenses in the accompanying consolidated statements of operations. Fair Value Measurements The fair value of financial instruments is based on estimates using quoted market prices, discounted cash flows or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and the estimated timing and amount of future cash flows. Therefore, the estimates of fair value may differ substantially from amounts that ultimately may be realized or paid at settlement or maturity of the financial instruments, and those differences may be material. Accordingly, the aggregate fair value amounts presented may not represent the Company’s underlying institutional value. The Company uses the three-tier hierarchy established by U.S. GAAP, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value to determine the fair value of its financial instruments. This hierarchy indicates to what extent the inputs used in the Company’s calculations are observable in the market. The different levels of the hierarchy are defined as follows: Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities. Level 2: Other than quoted prices that are observable in the market for the asset or liability, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or model-derived valuations or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3: Inputs are unobservable and reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. See Note 15 — Fair Value of Financial Instruments for additional information. Segments Business segments are defined as components of an enterprise about which discrete financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing operating performance. Based on the way the Company manages its business, the Company has determined that it currently operates with one reportable segment. The chief operating decision maker focuses on consolidated results in assessing operating performance and allocating resources. Furthermore, the Company offers similar products and services and uses similar processes to sell those products and services to similar classes of customers throughout the United States ("U.S."). Substantially all revenue is generated and all assets are held in the U.S. for all periods presented. Income Taxes The Company accounts for income taxes pursuant to the asset and liability method, which requires the recognition of deferred income tax assets and liabilities related to the expected future tax consequences arising from temporary differences between the carrying amounts and tax bases of assets and liabilities based on enacted statutory tax rates applicable to the periods in which the temporary differences are expected to reverse. Any effects of changes in income tax rates or laws are included in income tax expense in the period of enactment. The Company reduces the carrying amounts of deferred tax assets by a valuation allowance if, based on the evidence available, it is more likely than not that such assets will not be realized. In making the assessment under the more likely than not standard, appropriate consideration must be given to all positive and negative evidence related to the realization of the deferred tax assets. The assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of statutory carry forward periods by jurisdiction, the Company's experience with loss carryforwards not expiring unutilized and all tax planning alternatives that may be available. A valuation allowance is recognized if under applicable accounting standards the Company determines it is more likely than not that its deferred tax assets would not be realized.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets, Net	NOTE 4 — GOODWILL AND INTANGIBLE ASSETS On April 12, 2018, the Company acquired Car360, Inc. ("Car360"), a provider of app-based photo capture technology, for approximately $16.7 million, net of cash acquired of approximately $0.4 million. The purchase price was comprised of approximately $6.7 million cash, net of cash acquired, and approximately 0.5 million Class A Units of Carvana Group, with a fair value of approximately $10.0 million. The purchase price was allocated to net tangible assets of approximately $0.2 million and intangible assets of approximately $9.9 million based on their fair values on the acquisition date and a related deferred tax liability of approximately $2.5 million. The deferred tax liability will amortize over five seven The historical results of Car360 were not significant to the Company's consolidated results of operations for the periods presented.

Related Party Transactions [Abstract]
Related Party Transactions	NOTE 6 — RELATED PARTY TRANSACTIONS Lease Agreements In November 2014, the Company and DriveTime entered into a lease agreement that governs the Company’s access to and utilization of temporary storage, reconditioning, offices and parking space at various DriveTime inspection and reconditioning centers and retail facilities (the "DriveTime Lease Agreement"). The DriveTime Lease Agreement was most recently amended in December 2018. Lease duration varies by location with cancellable terms expiring between 2021 and 2024. Most of the retail facilities allow the Company to exercise up to two consecutive one In March 2017, the Company and DriveTime entered into a lease agreement that governs the Company's access to and utilization of office and parking space at various DriveTime retail facilities (the "DriveTime Hub Lease Agreement"). The DriveTime Hub Lease Agreement was most recently amended in December 2018. Lease expiration varies by location with most having cancellable terms expiring in 2021 and the Company having the right to exercise up to two consecutive one Under the DriveTime Lease Agreement and the DriveTime Hub Lease Agreement, the Company pays a monthly rental fee related to its pro rata utilization of space at each facility plus a pro rata share of each facility’s actual insurance costs and real estate taxes. At locations that the Company occupies all of the space it pays actual insurance costs and real estate taxes directly to the unrelated third party. The Company is additionally responsible for paying for any tenant improvements it requires to conduct its operations and its share of estimated costs incurred by DriveTime related to preparing these sites for use. As it relates to locations where the Company reconditions vehicles, the Company’s share of facility and shared reconditioning supplies expenses are related to the actual costs for operating the inspection and reconditioning centers and the Company’s pro rata share of total reconditioned vehicles and parking spaces at such inspection and reconditioning centers in a given month. Management has determined that the costs allocated to the Company are based on a reasonable methodology. In December 2016, the Company entered into a lease agreement related to a vehicle inspection and reconditioning center in Tolleson, Arizona, with Verde Investments, Inc., an affiliate of DriveTime ("Verde"), with an initial term of approximately 15 years. In August 2018, the Company entered into an additional lease agreement with a coterminous initial term with Verde for contiguous space to use in connection with such center.

The lease has an initial term of three Expenses related to these lease agreements are allocated based on usage to inventory and selling, general and administrative expenses in the accompanying consolidated balance sheets and statements of operations. Costs allocated to inventory are recognized as cost of sales when the inventory is sold. During the year ended December 31, 2018, total costs related to these lease agreements were approximately $8.8 million with approximately $4.4 million allocated to each of inventory and selling, general and administrative expenses. During the year ended December 31, 2017, total costs related to these lease agreements were approximately $7.2 million with approximately $2.8 million and $4.4 million allocated to inventory and selling, general and administrative expenses, respectively. During the year ended December 31, 2016, total costs related to these lease agreements were approximately $2.8 million with approximately $1.9 million and $0.9 million allocated to inventory and selling, general and administrative expenses, respectively. Corporate Office Leases In November 2015, the Company entered into a lease agreement with Verde for its then corporate headquarters. The rent expense incurred under this lease for the year ended December 31, 2016, was approximately $0.9 million. In December 2016, Verde sold the building, which the Company continued leasing through June 2017. During the first quarter of 2017, the Company subleased additional office space at DriveTime’s corporate headquarters in Tempe, Arizona. Pursuant to this arrangement, the Company incurred rent of approximately $0.1 million during the year ended December 31, 2017. This arrangement terminated in March 2017. In September 2016, the Company entered into a lease for the second floor of its corporate headquarters in Tempe, Arizona. DriveTime guarantees up to $0.5 million of the Company's rent payments under that lease through September 2019.

The lease and sublease each have a term of 83 months, subject to the right to exercise three five Master Dealer Agreement In December 2016, the Company entered into a master dealer agreement with DriveTime (the "Master Dealer Agreement"). Pursuant to this agreement, the Company may sell vehicle service contracts ("VSCs") to customers purchasing a vehicle from the Company. The Company earns a commission on each VSC sold to its customers and DriveTime is obligated by and subsequently administers the VSCs. The Company collects the retail purchase price of the VSCs from its customers and remits the purchase price net of commission to DriveTime. During the years ended December 31, 2018, 2017 and 2016, the Company recognized approximately $23.7 million, $8.9 million and $0.2 million, respectively, of commissions earned on VSCs sold to its customers and administered by DriveTime, net of a reserve for estimated contract cancellations. The commission earned on the sale of these VSCs is included in other sales and revenues in the accompanying consolidated statements of operations. On November 5, 2018, the Company amended the Master Dealer Agreement to allow the Company to receive payments for excess reserves based on the performance of the VSCs versus the reserves held by the VSC administrator, once a required claims period for such VSCs has passed. During the year ended December 31, 2018, the Company recognized approximately $1.9 million related to payments for excess reserves to which it expects to be entitled, which is included in other sales and revenues in the accompanying consolidated statement of operations. Beginning in 2017, DriveTime also administers a portion of the Company's GAP waiver coverage and the limited warranty provided to all customers under the Master Dealer Agreement. The Company pays a per-contract fee to DriveTime to administer a portion of the GAP waiver coverage it sells to its customers and a per-vehicle fee to DriveTime to administer the limited warranty included with every purchase. The Company incurred approximately $2.2 million and $0.6 million during the years ended December 31, 2018 and 2017, respectively, related to the administration of GAP waiver coverage and limited warranty.

Aircraft Time Sharing Agreement The Company entered into an agreement to share usage of two aircraft owned by Verde and operated by DriveTime on October 22, 2015, and the agreement was subsequently amended on May 15, 2017. Pursuant to the agreement, the Company agreed to reimburse DriveTime for actual expenses for each of its flights. The original agreement was for 12 months, with perpetual 12-month automatic renewals. Either the Company or DriveTime can terminate the agreement with 30 days’ prior written notice. The Company reimbursed DriveTime approximately $0.5 million, $0.4 million and $0.6 million under this agreement during the years ended December 31, 2018, 2017 and 2016, respectively. Shared Services Agreement with DriveTime In November 2014, the Company and DriveTime entered into a shared services agreement whereby DriveTime provided certain accounting and tax, legal and compliance, information technology, telecommunications, benefits, insurance, real estate, equipment, corporate communications, software and production and other services to facilitate the transition of these services to the Company on a standalone basis (the "Shared Services Agreement"). The Shared Services Agreement was most recently amended and restated in April 2017 and operates on a year-to-year basis after February 2019, with the Company having the right to terminate any or all services with 30 days' prior written notice and DriveTime having the right to terminate any or all services with 90 days' prior written notice. As of December 31, 2018, DriveTime only provides the Company with information technology and telecommunications at certain hubs it leases from DriveTime under the DriveTime Lease Agreement and the DriveTime Hub Lease Agreement under the Shared Services Agreement. Charges allocated to the Company are based on the Company’s actual use of the specific services detailed in the Shared Services Agreement. Total expenses related to the shared services agreement were approximately $0.0 million, $0.1 million and $0.7 million for the years ended December 31, 2018, 2017 and 2016, respectively, which are included in selling, general and administrative expenses in the accompanying consolidated statements of operations.

His contributions are intended to fund equity awards of 165 restricted stock units to each of the Company's then-current employees upon their satisfying certain employment tenure requirements. The Company entered into certain contribution agreements related to his commitment in order to effect the transfer of shares from Mr. Garcia to the Company. The Company does not expect Mr. Garcia to incur any tax obligations related to the Share Contribution, but pursuant to a series of Contribution Agreements, it has indemnified Mr. Garcia from any such obligations that may arise. See Note 9 — Stockholders' Equity and Note 11 — Equity-Based Compensation for further discussion. Accounts Payable Due to Related Party Amounts payable to DriveTime and Verde under the agreements explained above, as well as invoices DriveTime initially paid on behalf of the Company for vehicle reconditioning costs and general and administrative expenses, are included in accounts payable to related party in the accompanying consolidated balance sheets.

The Company recorded a loss of approximately $0.8 million related to this disposal, which is included in cost of sales on the accompanying consolidated statement of operations. Repurchase of Finance Receivables from DriveTime On January 20, 2016, the Company repurchased approximately $72.4 million of finance receivables from DriveTime related to loans the Company originated and previously sold under the terms of the DriveTime receivable purchase agreement (the "DriveTime Receivable Purchase Agreement"), discussed below, for a price of approximately $74.6 million.

The Company has not sold any finance receivables under this agreement subsequent to 2016, and DriveTime is not obligated to make any additional purchases under the agreement. IP License Agreement In February 2017, the Company entered into a license agreement that governs the rights of certain intellectual property owned by the Company and the rights of certain intellectual property owned by DriveTime. The license agreement, which was amended and restated in April 2017, generally provides that each party grants to the other certain limited exclusive (other than with respect to the licensor party and its affiliates) and non-exclusive licenses to use certain of its intellectual property, and each party agrees to certain covenants not to sue the other party, its affiliates and certain of its service providers in connection with various patent claims.

Also on November 3, 2017, the Company terminated the remaining capacity under the 2016 Master Transfer Agreement and replaced this facility by entering into a new master transfer agreement (the "2017 Master Transfer Agreement") with a purchaser trust under which the trust committed to purchase up to an aggregate of $357.1 million in principal balances of finance receivables. On November 2, 2018, the Company amended the 2017 Master Transfer Agreement to, among other things and subject to the terms of the agreement, increase and extend the trust's commitment to purchase finance receivables from the Company. The trust's currently available financing following the amendment permits up to $454.5 million in principal balances of finance receivables to be purchased, and the 2017 Master Transfer Agreement's purchase commitment contemplates the trust securing up to three times the currently available financing in the aggregate. Also on November 2, 2018, the Company amended the Purchase and Sale Agreement to, among other things and subject to the terms of the agreement, commit the trust to purchase up to a maximum of $1.25 billion of principal balances of finance receivables during the remaining term of the agreement.

The Senior Notes accrue interest at a rate of 8.875% per annum, which is payable semi-annually in arrears on April 1 and October 1 of each year beginning April 1, 2019. The Senior Notes mature on October 1, 2023, unless earlier repurchased or redeemed, and are guaranteed by the Company's existing domestic restricted subsidiaries (other than the subsidiaries formed solely for the purpose of facilitating the Company's sales of its finance receivables, if any). The Company may redeem some or all of the Senior Notes on or after September 1, 2020 at redemption prices set forth in the Indenture, plus any accrued and unpaid interest to the redemption date. Prior to September 1, 2020, the Company may redeem up to 35.0% of the aggregate principal amount of the Senior Notes at a redemption price equal to 108.875%, together with accrued and unpaid interest to, but not including, the date of redemption, with the net cash proceeds of certain equity offerings. In addition, the Company may, at its option, redeem some or all of the Senior Notes prior to October 1, 2020, by paying a make-whole premium plus any accrued and unpaid interest, to, but not including, the redemption date. If the Company experiences certain change of control events, it must make an offer to purchase all of the Senior Notes at 101.0% of the principal amount thereof, plus any accrued and unpaid interest, to the repurchase date. The Indenture governing the Senior Notes contains restrictive covenants that limit the ability of the Company to, among other things, incur additional debt or issue preferred stock, create liens, create restrictions on the Company’s ability to make intercompany payments, pay dividends and make other distributions in respect of the Company's capital stock, redeem or repurchase the Company’s capital stock or prepay subordinated indebtedness, make certain investments or certain other restricted payments, guarantee indebtedness, designate unrestricted subsidiaries, sell certain kinds of assets, enter into certain types of transactions with affiliates, and effect mergers or consolidations.

As of December 31, 2018, the Company was in compliance with all covenants. The outstanding principal of the Senior Notes, net of unamortized debt issuance costs, was approximately $342.9 million as of December 31, 2018, of which $15.0 million of principal was held by Verde, and is included as long-term debt in the accompanying consolidated balance sheet. In connection with the issuance of these Senior Notes, Carvana Group amended its LLC agreement to create a class of non-convertible preferred units, which Carvana Co. purchased with its net proceeds from the issuance of these Senior Notes, as further discussed in Note 9 — Stockholders' Equity.

As of December 31, 2018, none of these transactions have qualified for sale accounting due to forms of continuing involvement, such as repurchase options or renewal periods that extend the lease for substantially all of the asset's remaining useful life, and are therefore accounted for as financing transactions. These arrangements require monthly payments and have initial terms of twenty twenty In November 2017, the Company entered into a master sale-leaseback agreement (the "Master Sale-Leaseback Agreement" or "MSLA"), which was amended in November 2018, pursuant to which it may sell and lease back certain of its owned or leased properties and construction improvements. Under the MSLA, at any time the Company may elect to, and beginning in November 2020 or until a property owner of a leased site consents to the sale-leaseback, the purchaser has the right to, demand that the Company repurchase one or more properties sold and leased back pursuant to the MSLA for an amount equal to the repurchase price. Repurchase prices are defined in each of the applicable leases and are generally the original purchase prices plus any accrued and unpaid rent.

On December 5, 2017, Carvana Co. amended and restated its certificate of incorporation to authorize 100,000 shares of Convertible Preferred Stock, with an initial stated value of $1,000 per share and a par value of $0.01 per share. Each share of Class A common stock generally entitles its holder to one vote on all matters to be voted on by stockholders. Each share of Class B common stock held by the Garcia Parties generally entitles its holder to ten votes on all matters to be voted on by stockholders, for so long as the Garcia Parties maintain direct or indirect beneficial ownership of at least 25% of the outstanding shares of Carvana Co.'s Class A common stock determined on an as-exchanged basis assuming that all of the Class A Units and Class B Units were exchanged for Class A common stock. All other shares of Class B common stock generally entitle their holders to one vote per share on all matters to be voted on by stockholders. Holders of Class B common stock are not entitled to receive dividends and would not be entitled to receive any distributions upon the liquidation, dissolution or winding down of the Company. Holders of Class A and Class B common stock vote together as a single class on all matters presented to stockholders for their vote or approval, except as otherwise required by applicable law. As described in Note 1 — Business Organization, Carvana Group amended and restated its LLC Agreement to, among other things, provide for two classes of common ownership interests in Carvana Group. Carvana Group’s two remaining classes of membership interests are Class A Units and Class B Units. Carvana Co. is required to, at all times, maintain (i) a four-to-five ratio between the number of shares of Class A common stock issued by Carvana Co. and the number of Class A Units owned by Carvana Co. (subject to certain exceptions for treasury shares and shares underlying certain convertible or exchangeable securities and subject to adjustment as set forth in the exchange agreement (the "Exchange Agreement") further discussed below, and taking into account Carvana Sub’s 0.1% ownership interest in Carvana, LLC) and (ii) a four-to-five ratio between the number of shares of Class B common stock owned by the Original LLC Unitholders and the number of Class A Units owned by the Original LLC Unitholders. The Company may issue shares of Class B common stock only to the extent necessary to maintain these ratios. Shares of Class B common stock are transferable only together with an equal number of LLC Units if Carvana Co., at the election of an Original LLC Unitholder, exchanges LLC Units for shares of Class A common stock. As of December 31, 2018, there were approximately 182.3 million and 5.6 million Class A Units and Class B Units (as adjusted for the participation thresholds), respectively, issued and outstanding. As of December 31, 2017, there were approximately 165.8 million and 6.0 million Class A Units and Class B Units (as adjusted for the participation thresholds), respectively, issued and outstanding. As discussed in Note 11 — Equity-Based Compensation, Class B Units were issued under the Company’s LLC Equity Incentive Plan through the completion of the IPO (the "LLC Equity Incentive Plan") and are subject to a participation threshold and are earned over the requisite service period. Initial Public Offering As described in Note 1 — Business Organization, on May 3, 2017, Carvana Co. completed its IPO of 15.0 million shares of Class A common stock at a public offering price of $15.00 per share. Carvana Co. received approximately $205.8 million in proceeds, net of underwriting discounts and commissions and offering expenses. Carvana Co. used the proceeds to purchase approximately 18.8 million newly-issued LLC Units of Carvana Group at a price per unit equal to 0.8 times the initial public offering price less underwriting discounts and commissions. In connection with the IPO, Carvana Co. transferred approximately 0.2 million Class A Units to Ernest Garcia II in exchange for his 0.1% ownership interest in Carvana, LLC, a majority-owned subsidiary of Carvana Group. After the transfer Carvana Co. owned approximately 18.6 million Class A Units. The Company incurred approximately $4.9 million of legal, accounting, printing and other professional fees directly related to the IPO, including $1.3 million incurred during 2016, of which $0.4 million were paid during 2016. Upon completion of the IPO, the total costs incurred for the IPO were charged against additional paid-in capital. Follow-On Public Offering On April 30, 2018, the Company completed a follow-on offering of 6.6 million shares of its Class A common stock at a public offering price of $27.50 per share and received net proceeds from the offering of approximately $172.3 million after underwriting discounts and commissions and offering expenses. The Company used the net proceeds to purchase approximately 8.3 million newly-issued LLC Units in Carvana Group, which used the net proceeds primarily for general corporate purposes. The Selling Stockholder and the Selling LLC Unitholders sold a total of approximately 6.1 million shares of Class A common stock as part of the offering. The Selling LLC Unitholders exchanged approximately 6.9 million LLC Units for approximately 5.6 million shares of Class A common stock to be sold in the offering, and to the extent such Selling LLC Unitholder held Class B common stock, the corresponding shares of Class B common stock were immediately retired by the Company. The Company did not receive any proceeds from the sale of the approximately 6.1 million shares of Class A common stock by the Selling Stockholder and the Selling LLC Unitholders. Exchange Agreement Carvana Co. and the LLC Unitholders entered into an Exchange Agreement under which each LLC Unitholder (and certain permitted transferees thereof) may receive shares of the Company's Class A common stock in exchange for their LLC Units on a four-to-five conversion ratio, or cash at the option of the Company, subject to conversion ratio adjustments for stock splits, stock dividends, reclassifications and similar transactions and subject to vesting for certain Class A Units and subject to vesting and the respective participation threshold for Class B Units. To the extent such owners also hold Class B common stock, they will be required to deliver to Carvana Co. a number of shares of Class B common stock equal to the number of shares of Class A common stock being exchanged for. Any shares of Class B common stock so delivered will be canceled. The number of exchangeable Class B Units is determined based on the value of Carvana Co.'s Class A common stock and the applicable participation threshold. During the years ended December 31, 2018 and December 31, 2017, certain LLC Unitholders exchanged 14.2 million and 3.3 million LLC Units and 10.3 million and 2.6 million shares of Class B common stock for 11.3 million and 2.6 million newly-issued shares of Class A common stock, respectively. Simultaneously, and in connection with these exchanges, Carvana Co. received 14.2 million and 3.3 million LLC Units during the years ended December 31, 2018 and December 31, 2017, respectively, increasing its total ownership interest in Carvana Group, and canceled the exchanged shares of Class B common stock. Class C Redeemable Preferred Units On April 27, 2016, the Company authorized the issuance of and sold approximately 18.3 million Class C Redeemable Preferred Units for approximately $100.0 million to Ernest Garcia II. On July 12, 2016, the Company authorized the issuance of and sold approximately 8.6 million Class C Redeemable Preferred Units to CVAN Holdings, LLC, and approximately 1.7 million Class C Redeemable Preferred Units to GV Auto I, LLC for approximately $50.0 million and $9.7 million, respectively. On December 9, 2016, the Company authorized the issuance of and sold approximately 0.5 million Class C Redeemable Preferred Units to the Fidel Family Trust for approximately $2.7 million. The Company recorded the issuance and sale of Class C Redeemable Preferred Units at fair value, net of issuance costs. In accordance with the Company’s Operating Agreement, the Class C Redeemable Preferred Units accrued a return (the "Class C Return") at a coupon rate of 12.5% compounding annually on the aggregate amount of capital contributions made with respect to the Class C Redeemable Preferred Units. On May 3, 2017, the Company closed its IPO at a price such that the Company is no longer liable for the accrued Class C Return, and the 43.1 million outstanding Class C Redeemable Preferred Units converted to Class A Units on a one-to-one basis and the related balance became a component of permanent equity on the accompanying consolidated balance sheet. Convertible Preferred Stock On December 5, 2017, Carvana Co. sold 100,000 shares of Convertible Preferred Stock for a purchase price of $100.0 million and net proceeds of approximately $98.5 million, which it used to purchase 100,000 Convertible Preferred Units of Carvana Group at a price per unit equal to the initial stated value of the Convertible Preferred Stock less issuance costs. The Convertible Preferred Stock has a par value of $0.01 per share and a liquidation value of $1,000 per share. At the holder's request beginning on January 29, 2018, any or all shares of the Convertible Preferred Stock were convertible into shares of Class A common stock at an initial conversion rate of approximately 50.78 shares of Class A common stock per share of Convertible Preferred Stock. On or after December 5, 2018, the Company had the option to cause all Convertible Preferred Shares to be converted into shares of Class A common stock or cash, at the Company's election, if the 10-day volume-weighted average price equals or exceeds 150% of the conversion price as set forth in the agreement. In the event Carvana Co. issued any shares of Class A common stock upon conversion of any shares of Convertible Preferred Stock or in connection with any change of control repurchase of shares of Convertible Preferred Stock, a corresponding number of Convertible Preferred Units would be canceled and cease to be outstanding, and Carvana Group will issue Class A Units to Carvana Co. on a four-to-five ratio between the number of shares of Class A common stock issued by Carvana Co. to the holders of the Convertible Preferred Stock and the number of Class A Units issued. During the year ended December 31, 2018, at the holder's request 75,000 shares of Convertible Preferred Stock, and at the Company's election 25,000 shares of Convertible Preferred Stock, were converted into a total of approximately 5.1 million shares of Class A common stock. Simultaneously, and in connection with these conversions, 100,000 Convertible Preferred Units were canceled and Carvana Group issued approximately 6.3 million Class A Units to Carvana Co. The initial conversion price was $19.6945, which was calculated based on a 20.0% premium to the volume weighted average price for Class A common stock during the 5 trading days immediately preceding December 4, 2017. Following announcement of the transaction, the share price of Class A common stock increased and exceeded the conversion price on the commitment date and resulted in a beneficial conversion feature ("BCF") of approximately $2.6 million. The BCF was originally recorded as a reduction of the Convertible Preferred Stock with an offset to additional paid-in capital. The BCF accreted as a deemed dividend through January 29, 2018, the first available conversion date, increasing the carrying value of the Convertible Preferred Stock with an offsetting charge to additional paid-in capital. During the years ended December 31, 2018 and 2017, the Company recorded approximately $1.4 million and $1.2 million, respectively, in accretion related to the BCF. The carrying value of the Convertible Preferred Stock was $0.0 million as of December 31, 2018 and approximately $97.1 million as of December 31, 2017. Upon a change of control, as defined in the agreement, any holder of Convertible Preferred Stock had the option to require the Company (or its successor) to purchase, any or all of its Convertible Preferred Stock at a purchase price per share, payable at the Company’s option in any combination of cash or shares of Class A common stock, of 101% of the liquidation preference, plus all accumulated dividends. Holders of the Convertible Preferred Stock had no voting rights. The Convertible Preferred Stock ranked senior, as to payment of dividends and distributions of assets upon the liquidation, dissolution or winding up of Company, to the Company’s common stock and any shares of capital stock of the Company not expressly ranking senior to or pari passu with the Convertible Preferred Stock, and junior to all shares of capital stock of the Company issued after the issuance of the Convertible Preferred Stock, if the terms of which expressly provided that such shares would rank senior to the Convertible Preferred Stock. The Convertible Preferred Stock accrued dividends at 5.5% per annum of the liquidation preference of $1,000 per share. The dividends were payable in cash quarterly commencing March 15, 2018 so long as the Company had funds legally available and the Board declared a cash dividend payable. The Company could not declare dividends on shares of its common stock or purchase or redeem shares of its common stock, unless all accumulated and unpaid dividends on the Convertible Preferred Stock had been paid in full or a sum for such amounts had been set aside for payment. As the Company declared and paid dividends on the Convertible Preferred Stock, Carvana Group made distributions to Carvana Co. with respect to the Convertible Preferred Units in an amount equal to the related Convertible Preferred Stock dividend amount and any corresponding tax payments. During the year ended December 31, 2018, the Company paid approximately $4.6 million of dividends to the holders of the Convertible Preferred Stock and Carvana Group distributed approximately $4.6 million to Carvana Co. with respect to the Convertible Preferred Units. As of December 31, 2018, all of the Convertible Preferred Stock had been converted into shares of Class A common stock, thus, there are no outstanding shares of Convertible Preferred Stock and no related accrued dividends. Class A Non-Convertible Preferred Units On October 2, 2018, Carvana Group amended its LLC Agreement to create a class of non-convertible preferred units (the "Class A Non-Convertible Preferred Units"), effective September 21, 2018. The Class A Non-Convertible Preferred Units were created in connection with Carvana Co.'s issuance of the Senior Notes, as discussed further in Note 8 — Debt Instruments. Carvana Co. used its net proceeds from the Senior Notes to purchase 350,000 Class A Non-Convertible Preferred Units. In the event Carvana Co. makes payments on the Senior Notes, Carvana Group will make an equal cash distribution to the Class A Non-Convertible Preferred Units. For each $1,000 principal amount of Senior Notes that Carvana Co. repays or otherwise retires, one Class A Non-Convertible Preferred Unit shall be canceled and retired. Contributions of Class A Common Shares From Ernest Garcia III During the year ended December 31, 2018, the Company and its Chief Executive Officer, Ernest Garcia III, entered into contribution agreements (the "Contribution Agreements") in connection with the 100k Milestone Gift, as defined in Note 11 — Equity-Based Compensation , pursuant to which Mr. Garcia contributed approximately 0.2 million shares of the Company's Class A common stock to the Company, at no charge. The Company subsequently granted the first two tranches of the 100k Milestone Gift of approximately 0.2 million restricted stock units, refer to Note 11 — Equity-Based Compensation for further

Noncontrolling Interest [Abstract]
Non-controlling Interests	NOTE 10 — NON-CONTROLLING INTERESTS As discussed in Note 1 — Business Organization, Carvana Co. consolidates the financial results of Carvana Group and reports a non-controlling interest related to the portion of Carvana Group owned by the LLC Unitholders. Changes in the ownership interest in Carvana Group while Carvana Co. retains its controlling interest will be accounted for as equity transactions. Exchanges of LLC Units result in a change in ownership and reduce the amount recorded as non-controlling interests and increase additional paid-in capital. Upon the issuance of shares of Class A common stock by Carvana Co. related to the Company's equity compensation plans such as the exercise of options, issuance of restricted or non-restricted stock, payment of bonuses in stock or settlement of stock appreciation rights in stock, Carvana Group is required to issue to Carvana Co. a number of Class A Units equal to 1.25 times the number of shares of Class A common stock being issued in connection with the exercise of such options or issuance of other types of equity compensation, subject to adjustment for stock splits, stock dividends, reclassifications and similar transactions. Activity related to the Company's equity compensation plans may result in a change in ownership which will impact the amount recorded as non-controlling interest and additional paid-in capital. The non-controlling interest related to the Class B Units is determined based on the respective participation thresholds and the share price of Class A common stock on an as-converted basis. To the extent that the number of as-converted Class B Units change or Class B Units are forfeited, the resulting difference in ownership will be accounted for as equity transactions adjusting the non-controlling interest and additional paid-in capital. During the year ended December 31, 2018, the total adjustments related to exchanges of LLC Units was a decrease in non-controlling interests and a corresponding increase in additional paid-in capital of approximately $15.8 million, which has been included in exchanges of LLC Units in the accompanying consolidated statement of stockholders' equity. During the year ended December 31, 2018, Carvana Co. utilized its net proceeds from its follow-on offering to purchase LLC Units, which together with the follow-on offering resulted in an adjustment to increase non-controlling interests and to decrease additional paid-in capital by approximately $132.4 million, which has been included in adjustment to noncontrolling interests related to follow-on offering in the accompanying consolidated statement of stockholders' equity. During the year ended December 31, 2018, Carvana Group issued approximately 0.5 million Class A Units with a fair value of approximately $10.0 million as part of the purchase price consideration for Car360, which is reflected as an increase in non-controlling interests in the accompanying consolidated statement of stockholders' equity. The adjustment related to the issuance of Class A Units to acquire Car360 was a decrease in noncontrolling interests and a corresponding increase in additional paid-in capital of approximately $1.3 million, which has been included in adjustment to non-controlling interests related to business acquisitions in the accompanying consolidated statement of stockholders' equity. During the year ended December 31, 2018, the 100,000 shares of Convertible Preferred Stock converted into approximately 5.1 million shares of Class A common stock, Carvana Co. canceled and retired 100,000 Convertible Preferred Units, and Carvana Group issued approximately 6.3 million Class A Units to Carvana Co. The adjustment related to the conversion of Convertible Preferred Stock was an increase in non-controlling interests and a corresponding decrease in additional paid-in capital of approximately $68.0 million, which has been included in adjustment to non-controlling interests related to conversion of Class A Convertible Preferred Stock in the accompanying consolidated statement of stockholders' equity. As of December 31, 2018, Carvana Co. owned approximately 27.2% of Carvana Group with the LLC Unitholders owning the remaining 72.8%. The net loss attributable to the non-controlling interests on the accompanying consolidated statement of operations represents the portion of the net loss attributable to the economic interest in Carvana Group held by the non-controlling LLC Unitholders calculated based on the weighted average non-controlling interests' ownership during the periods presented.

Equity-Based Compensation	NOTE 11 — EQUITY-BASED COMPENSATION Equity-based compensation expense is recognized based on amortizing the grant-date fair value on a straight-line basis over the requisite service period, which is generally the vesting period of the award, less actual forfeitures. A summary of equity based compensation expense recognized during the years ended December 31, 2018, 2017 and 2016 is as follows (in thousands): For the Years Ended December 31, 2018 2017 2016 Class B Units $ 2,474 $ 1,771 $ 555 Restricted Stock Units and Awards excluding those granted in relation to the 100k Milestone Gift 6,897 2,662 — Restricted Stock Units granted in relation to the 100k Milestone Gift 12,120 — — Options 2,357 1,178 — Class A Units 1,897 — — Total equity-based compensation 25,745 5,611 555 Equity-based compensation capitalized to property and equipment (1,650) — — Equity-based compensation capitalized to inventory (3,776) — — Equity-based compensation, net of capitalized amounts $ 20,319 $ 5,611 $ 555 During the year ended December 31, 2018, the Company capitalized approximately $1.7 million of equity-based compensation to property and equipment related to software development and real estate projects and approximately $3.8 million to inventory related to reconditioning and inbound transportation of vehicles. Prior to 2018, amounts capitalized to property and equipment and inventory were immaterial. All other equity-based compensation is included in selling, general and administrative expenses in the accompanying consolidated statements of operations. As of December 31, 2018, unrecognized equity-based compensation related to outstanding awards and the related weighted-average period over which it is expected to be recognized subsequent to December 31, 2018 is presented in the table below. Total unrecognized equity-based compensation expense will be adjusted for actual forfeitures.

Under the 2017 Incentive Plan 14.0 million shares of Class A common stock are available for issuance, which the Company may grant as stock options, stock appreciation rights, restricted stock, restricted stock units and other stock-based awards to employees, directors, officers and consultants. The majority of the Company's equity awards vest over three five Restricted Stock Awards and Restricted Stock Units Restricted stock awards ("RSAs") entitle recipients to vote and to receive all dividends declared with respect to such shares, payable upon vesting. RSAs vest over a period of one five Restricted stock units ("RSUs") do not entitle recipients to vote or receive dividends. RSUs generally vest over a period of one five thirty RSA and RSU activity during the years ended December 31, 2018 and 2017 was as follows: Number of RSAs/RSUs (in thousands) Weighted-Average Grant-Date Fair Value Outstanding at January 1, 2017 — n/a Granted 584 $ 17.11 Settled (135) $ 15.91 Forfeited (29) $ 15.06 Outstanding at December 31, 2017 (1) 420 $ 17.63 Granted 791 $ 46.19 Settled (391) $ 42.35 Forfeited (56) $ 21.64 Outstanding at December 31, 2018 (1) 764 $ 34.25 (1) All outstanding RSAs and RSUs at December 31, 2018 and 2017 are nonvested. Non-Qualified Stock Options Non-qualified stock options allow recipients to purchase shares of Class A common stock at a fixed exercise price. The fixed exercise price is equal to the price of a share of Class A common stock at the time of grant. The options typically vest 20% or 25% on the anniversary of the grant date and in equal monthly installments thereafter for a total vesting period of four five ten Stock option activity during the years ended December 31, 2018 and 2017 was as follows (shares and intrinsic value in thousands): Number of Options Weighted-Average Exercise Price Weighted-Average Remaining Contractual Life (in years) Aggregate Intrinsic Value Outstanding at January 1, 2017 — Options granted 784 $ 15.58 n/a Options exercised (3) $ 15.00 $ 14 Options forfeited or expired (26) $ 15.00 n/a Outstanding at December 31, 2017 755 $ 15.60 9.5 $ 3,000 Options granted 294 $ 44.81 Options exercised (60) $ 13.26 $ 1,224 Options forfeited or expired (58) $ 16.15 Outstanding at December 31, 2018 931 $ 24.95 8.9 $ 11,306 Vested and exercisable as of December 31, 2018 188 $ 15.62 8.5 $ 3,206 Expected to vest as of December 31, 2018 743 $ 27.30 9 $ 8,100 The Company determined the grant-date fair value of the options granted during the years ended December 31, 2018 and 2017 using the Black-Scholes valuation model with the following weighted-average assumptions: Years Ended December 31, 2018 2017 Expected volatility (1) 65.5 % 63.0 % Expected dividend yield — % — % Expected term (in years) (2) 6.00 6.27 Risk-free interest rate 3.0 % 2.0 % Weighted-average grant-date fair value per option $26.93 $9.18 (1) Measured using the Company's historical data and selected high-growth guideline companies and considering the risk factors that would influence the range of expected volatility because the Company does not have sufficient historical data to provide a reasonable basis upon which to estimate the expected volatility for the entirety of the term. (2) Expected term represents the estimated period of time until an option is exercised and was determined using the simplified method because the Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term. Class A Units During the year ended December 31, 2018, the Company granted certain employees approximately 0.4 million Class A Units with service-based vesting over two four A summary of the Class A Unit activity for the year ended December 31, 2018 is as follows: Class A Units Number of Class A Units (in thousands) Weighted-Average Grant Date Fair Value Outstanding at January 1, 2018 — n/a Granted 393 $ 18.58 Exchanged — n/a Forfeited — n/a Outstanding at December 31, 2018 393 Vested as of December 31, 2018 — n/a Expected to vest as of December 31, 2018 393 $ 18.58 Class B Units In March 2015, Carvana Group adopted the LLC Equity Incentive Plan. Under the LLC Equity Incentive Plan, Carvana Group could grant up to 10.0 million Class B Units to eligible employees, non-employee officers, consultants and directors with service vesting conditions. In connection with the completion of the IPO, Carvana Group discontinued the grant of new awards under the LLC Equity Incentive Plan, however the LLC Equity Incentive Plan will continue in connection with administration of existing awards that remain outstanding. The awards granted under the LLC Equity Incentive Plan are earned over the requisite service period, which is typically four five Carvana Co., subject to conversion ratio adjustments for stock splits, stock dividends, reclassifications and similar transactions and subject to vesting and the respective participation threshold for Class B Units. Class B Units do not expire. A summary of the Class B Unit activity for the year ended December 31, 2018, 2017, and 2016 is as follows: Class B Units Number of Class B Units (in thousands) Weighted-Average Participation Threshold per Class B Unit Outstanding at January 1, 2016 5,645 $ 1.17 Granted 1,313 $ 5.40 Forfeited (218) $ 3.64 Outstanding at December 31, 2016 6,740 $ 1.91 Granted 767 $ 12.00 Exchanged (51) $ 1.81 Forfeited (35) $ 3.48 Outstanding at December 31, 2017 7,421 $ 2.95 Granted — n/a Exchanged (901) $ 0.96 Forfeited (127) $ 10.49 Outstanding at December 31, 2018 6,393 $ 3.08 Vested as of December 31, 2018 4,549 $ 2.21 Expected to vest as of December 31, 2018 1,844 $ 5.22 The Company used a third party valuation specialist to assist management in its estimation of the grant-date fair value of the Class B Units on the respective grant dates during 2016 and 2017. There were no Class B Units granted in 2018. As the participation threshold provides a threshold similar to that of an exercise price for a stock option, the Company used option pricing valuation models with the following weighted-average assumptions: 2017 2016 Expected volatility (1) 63.0 % 68.0 % Expected dividend yield — % — % Expected term (in years) (2) 6.3 1.8 Risk-free interest rate 1.9 % 0.9 % Weighted-average grant date fair value per Class B Unit $ 7.04 $ 0.34 (1) Measured using selected high-growth guideline companies and considering the risk factors that would influence the range of expected volatility because the Company does not have sufficient historical data to provide a reasonable basis upon which to estimate the expected volatility. (2) In 2017, the expected term represents the estimated period of time until an award is exchanged and was determined using the simplified method because the Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term. Company Performance Plan The Company created the Performance Plan on July 25, 2016, whereby the Company was authorized to grant up to 1.0 million performance units (the "Performance Units") to certain employees and consultants. The Performance Units granted were subject to continued employment and were only exercisable upon a qualifying transaction, which included an initial public offering, as defined in the Performance Plan. The IPO completed on May 3, 2017 constituted a qualifying transaction under the terms of the Performance Plan. The Company chose to settle the outstanding Performance Units in equity awards of Carvana Co. and recognized compensation expense related to the vested portion of these equity awards upon completion of the IPO.

Earnings Per Share [Abstract]
Loss Per Share	NOTE 12 — LOSS PER SHARE Basic and diluted net loss per share is computed by dividing the net loss attributable to Class A common stockholders by the weighted-average shares of Class A common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potentially dilutive shares. For all periods presented, potentially dilutive shares are excluded from diluted net loss per share because they have an anti-dilutive impact. Therefore, basic and diluted net loss per share attributable to Class A common stockholders are the same for all periods presented. As discussed in Note 1 — Business Organization, the Organizational Transactions are considered transactions between entities under common control and the financial statements for periods prior to the IPO and Organizational Transactions have been adjusted to combine the previously separate entities for presentation purposes. For purposes of calculating both the numerator and denominator of net loss per share for periods prior to the IPO, the Company has retroactively reflected the 15.0 million shares issued in the IPO and the LLC Units outstanding as of the Organizational Transactions as if they had been issued and outstanding as of the beginning of each period presented. These calculations for periods prior to the IPO do not consider the options or shares of Class A common stock issued on the IPO date under the 2017 Incentive Plan. The following table presents the calculation of basic and diluted net loss per share during the years ended December 31, 2018, 2017 and 2016 (in thousands, except per share data): For the years ended December 31, 2018 2017 2016 Numerator: Net loss $ (254,745) $ (164,316) $ (93,112) Net loss attributable to non-controlling interests 192,991 146,003 82,963 Dividends on Class A convertible preferred stock (4,206) (413) — Accretion of beneficial conversion feature on Class A convertible preferred stock (1,380) (1,237) — Net loss attributable to Carvana Co.

As such, separate presentation of basic and diluted net loss per share of Class B common stock under the two-class method has not been presented. LLC Units (adjusted for the Exchange Ratio and participation thresholds) are considered potentially dilutive shares of Class A common stock because they are exchangeable into shares of Class A common stock. Weighted-average as-converted shares of Convertible Preferred Stock of approximately 3.9 million, 0.4 million and 0.0 million for the years ended December 31, 2018, 2017 and 2016, respectively, were evaluated under the if-converted method for potentially dilutive effects and were determined to be anti-dilutive. Weighted-average as-converted Class A Units of approximately 109.0 million, 117.0 million and 117.2 million together with the related Class B common stock for the years ended December 31, 2018, 2017 and 2016, respectively, were evaluated under the if-converted method for potentially dilutive

During the year ended December 31, 2018, the Company recorded a gross deferred tax asset of $95.2 million associated with the basis difference in its investment in Carvana Group related to the acquisition of these LLC Units which is reflected as an increase to additional paid-in capital in the accompanying statements of stockholders' equity. As described in Note 1 — Business Organization and Note 9 — Stockholders' Equity, Carvana Co. purchased approximately 18.8 million newly-issued LLC Units of Carvana Group in connection with the IPO. The Company recognized a gross deferred tax asset of $0.5 million associated with a portion of the basis difference resulting from this purchase of LLC Units which is reflected as an increase to additional paid-in capital in the accompanying statements of stockholders' equity. The Company has not recorded a deferred tax asset of $43.1 million related to the remaining basis difference associated with this purchase of LLC Units as the difference will only reverse upon the sale of its interest in Carvana Group. As described in Note 1 — Business Organization and Note 9 — Stockholders' Equity, Carvana Co. completed a follow-on offering of 6.6 million shares of its Class A common stock. The Company recognized a gross deferred tax asset of $2.5 million associated with the portion of the basis difference resulting from the purchase of LLC Units which is reflected as an increase to additional paid-in capital in the accompanying statement of stockholders' equity. The Company has not recorded a deferred tax asset of $30.6 million related to the remaining basis difference associated with the purchase of LLC Units as the difference will only reverse upon the sale of its interest in Carvana Group. During the year ended December 31, 2018, management performed an assessment of the recoverability of deferred tax assets. Management determined, based on the accounting standards applicable to such assessment, that there was sufficient negative evidence as a result of the Company’s cumulative losses to conclude it was more likely than not that its deferred tax assets would not be realized and has recorded a valuation allowance of $126.6 million. The Company has $2.2 million of deferred tax liabilities not available to offset deferred tax assets. In the event that management was to determine that the Company would be able to realize its deferred tax assets in the future in excess of their net recorded amount, an adjustment to the valuation allowance would be made which would reduce the provision for income taxes. On December 22, 2017, the U.S. government enacted tax legislation referred to as the 2017 Tax Cuts and Jobs Act (the "2017 Tax Act"). The 2017 Tax Act reduces the U.S. federal corporate tax rate from the previous rate of 35 to 21 effective January 1, 2018. The 2017 Tax Act also makes broad and complex changes to the U.S. tax code, including, but not limited to (i) limitations on net operating loss carryforwards created in tax years beginning after December 31, 2017 while also allowing such net operating losses to be carried forward indefinitely; (ii) bonus depreciation allowing full expensing of qualified property; (iii) limitations on the deductibility of certain executive compensation; and, (iv) limitations to the amount of deductible interest. On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 Income Tax Accounting Implications of the Tax Cuts and Jobs Act ("SAB 118") which provides guidance on accounting for the 2017 Tax Act’s impact. SAB 118 provides a measurement period, which in no case should extend beyond one year from the 2017 Tax Act enactment date, during which a company acting in good faith may complete the accounting for the impacts of the 2017 Tax Act under ASC Topic 740, Income Taxes ("ASC 740"). In accordance with SAB 118, the Company must reflect the income tax effects of the 2017 Tax Act in the reporting period in which it completes its analysis. The Company has recorded the impact of the Tax Act on its deferred tax balances related to the change in tax rate. During the year ended December 31, 2017, the Company recorded a decrease in its deferred tax assets of $9.3 million with a corresponding decrease in valuation allowance. SAB 118 allows the Company to refrain from making a decision on certain provisions in the 2017 Tax Act and the Company will continue to review and assess the potential impact of the legislation on its consolidated financial statements factoring in changes due to, among other things, further refinement of the Company's calculations, changes in interpretations and assumptions that the Company has made and additional guidance that may be issued by the U.S. government. As of December 31, 2018, the Company completed accounting for all of the enactment date income tax effects of the 2017 Tax Act and determined there were no material adjustments. Tax Receivable Agreement Carvana Co. expects to obtain an increase in its share of the tax basis in the net assets of Carvana Group when LLC Units are exchanged by the Existing LLC Unitholders and other qualifying transactions. As described in Note 9 — Stockholders' Equity, each change in outstanding shares of Class A common stock results in a corresponding increase or decrease in Carvana Co.'s ownership of LLC Units. The Company intends to treat any exchanges of LLC Units as direct purchases of LLC interests for U.S. federal income tax purposes. These increases in tax basis may reduce the amounts that Carvana Co. would otherwise pay in the future to various taxing authorities. They may also decrease gains (or increase losses) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets. In connection with the IPO, the Company entered into a Tax Receivable Agreement (the "TRA"). Under the TRA, the Company generally will be required to pay to the Existing LLC Unitholders 85% of the amount of cash savings, if any, in U.S. federal, state or local tax that the Company actually realizes directly or indirectly (or are deemed to realize in certain circumstances) as a result of (i) certain tax attributes created as a result of any sales or exchanges (as determined for U.S. federal income tax purposes) to or with the Company of their interests in Carvana Group for shares of Carvana Co.'s Class A common stock or cash, including any basis adjustment relating to the assets of Carvana Group and (ii) tax benefits attributable to payments made under the TRA (including imputed interest). The Company expects to benefit from the remaining 15% of any tax benefits that it may actually realize. To the extent that the Company is unable to timely make payments under the TRA for any reason, such payments generally will be deferred and will accrue interest until paid. If the Internal Revenue Service or a state or local taxing authority challenges the tax basis adjustments that give rise to payments under the TRA and the tax basis adjustments are subsequently disallowed, the recipients of payments under the agreement will not reimburse the Company for any payments the Company previously made to them. Any such disallowance would be taken into account in determining future payments under the TRA and would, therefore, reduce the amount of any such future payments. Nevertheless, if the claimed tax benefits from the tax basis adjustments are disallowed, the Company’s payments under the TRA could exceed its actual tax savings, and the Company may not be able to recoup payments under the TRA that were calculated on the assumption that the disallowed tax savings were available. The TRA provides that if (i) certain mergers, asset sales, other forms of business combinations, or other changes of control were to occur, (ii) there is a material breach of any material obligations under the TRA; or (iii) the Company elects an early termination of the TRA, then the TRA will terminate and the Company's obligations, or the Company's successor’s obligations, under the TRA will accelerate and become due and payable, based on certain assumptions, including an assumption that the Company would have sufficient taxable income to fully utilize all potential future tax benefits that are subject to the TRA and that any LLC Units that have not been exchanged are deemed exchanged for the fair market value of the Company's Class A common stock at the time of termination. As of December 31, 2018, the Company has concluded, based on applicable accounting standards, that it was more likely than not that its deferred tax assets subject to the TRA would not be realized; therefore, the Company has not recorded a liability related to the tax savings it may realize from utilization of such deferred tax assets. As of December 31, 2018, the total unrecorded TRA liability is approximately $110.8 million. If utilization of the deferred tax assets subject to the TRA becomes more likely than not in the future, the Company will record a liability related to the TRA which will be recognized as expense within its consolidated statements of operations.

Accrued Limited Warranty As part of its retail strategy, the Company provides a 100-day or 4,189-mile limited warranty to customers to repair certain broken or defective components of each used vehicle sold. As such, the Company accrues for such repairs based on actual claims incurred to-date and repair reserves based on historical trends. The liability was approximately $1.4 million and $0.8 million as of December 31, 2018 and 2017, respectively, and is included in accounts payable and other accrued liabilities in the accompanying consolidated balance sheets. Letters of Credit In October 2016, the Company obtained an unconditional, irrevocable, stand-by letter of credit for $1.9 million to satisfy a condition of a lease agreement. The Company was required to maintain a cash deposit of $1.9 million with the financial institution that issued the stand-by letter of credit until February 2018, at which point the cash deposit requirement was reduced by approximately $1.0 million. On November 30, 2018, the letter of credit expired. The Company earned interest on this letter of credit, and as of December 31, 2017, the balance with the financial institution was approximately $2.0 million and was included in restricted cash in the accompanying consolidated balance sheet. Legal Matters From time to time, the Company is involved in various claims and legal actions that arise in the ordinary course of business. Although the results of litigation and claims cannot be predicted with certainty, as of December 31, 2018 and 2017, the Company does not believe that the ultimate resolution of any legal actions, either individually or in the aggregate, will have a material adverse effect on its financial position, results of operations, liquidity and capital resources. Future litigation may be necessary to defend the Company and its partners by determining the scope, enforceability and validity of third party proprietary rights or to establish its own proprietary rights. The results of any current or future litigation cannot be predicted with certainty, and regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors.

Fair Value of Financial Instruments	NOTE 15 — FAIR VALUE OF FINANCIAL INSTRUMENTS Items Measured at Fair Value on a Recurring Basis As of December 31, 2018 and 2017, the Company held certain assets that were required to be measured at fair value on a recurring basis. The following is a summary of fair value measurements at December 31, 2018 and 2017 (in thousands): December 31, 2018 Carrying Value Level 1 Level 2 Level 3 Assets: Money market funds (1) $ 63,713 $ 63,713 $ — $ — December 31, 2017 Carrying Value Level 1 Level 2 Level 3 Assets: Money market funds (1) $ 171,859 $ 171,859 $ — $ — (1) Consist of highly liquid investments with original maturities of three months or less and classified in cash and cash equivalents in the accompanying consolidated balance sheets. Fair Value of Financial Instruments The carrying amounts of restricted cash, accounts receivable, accounts payable and accrued liabilities and accounts payable to related party approximate fair value because their respective maturities are less than three months. The carrying value of the Floor Plan Facility was determined to approximate fair value due to its short-term duration and variable interest rate that approximates prevailing interest rates as of each reporting period. The carrying value of notes payable and capital leases were determined to approximate fair value as each of the notes and leases have prevailing interest rates, which have not materially changed as of or during the years ended December 31, 2018 and 2017. The carrying value of finance leases was determined to approximate fair value as each of the transactions was entered into at prevailing interest rates during each respective period and they have not significantly fluctuated since inception. The fair value of the Senior Notes, which are not carried at fair value on the accompanying consolidated balance sheets, was determined using Level 2 inputs based on quoted market prices for the identical liability. The fair value of the Senior Notes as of December 31, 2018 was as follows (in thousands): December 31, 2018 Carrying value, net of unamortized debt issuance costs $ 342,869 Fair value 319,375 The fair value of finance receivables, which are not carried at fair value on the accompanying consolidated balance sheets, was determined utilizing the estimated sales price based on the historical experience of the Company. Such fair value measurement of the finance receivables, net is considered Level 2 under the fair value hierarchy.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). All intercompany balances and transactions have been eliminated.
Liquidity	LiquidityThe accompanying consolidated financial statements of the Company have been prepared in conformity with U.S. GAAP, which contemplate continuation of the Company as a going concern. The Company has incurred losses each year from inception through December 31, 2018, and expects to incur additional losses in the future. As the Company continues to grow into new markets, build vending machines and inspection and reconditioning centers and enhance technology and software development efforts, it needs access to substantial capital. From inception, the Company has primarily funded operations through the sale of Class A Units, the sale of Class C Redeemable Preferred Units, capital contributions from DriveTime, its IPO completed on May 3, 2017, for net proceeds of approximately $205.8 million, its follow-on offering completed on April 30, 2018, for net proceeds of approximately $172.3 million, its issuance of Class A Convertible Preferred Stock on December 5, 2017, for net proceeds of approximately $98.5 million, and the issuance of senior unsecured notes for net proceeds of approximately $342.5 million on September 21, 2018. The Company has historically funded vehicle inventory purchases through its Floor Plan Facility and had approximately $453.0 million available under its $650.0 million Floor Plan Facility that matures in October 2020 to fund future vehicle inventory purchases as of December 31, 2018, as described further in Note 8 — Debt Instruments. Further, the Company plans to increase the amount and maturity date of financing available to purchase vehicle inventory within the next year by amending its existing Floor Plan Facility or by entering into a new agreement. The Company has also funded some of its capital expenditures through long-term financing with lenders and other investors as described in further detail in Note 8 — Debt Instruments. The Company has historically entered into various agreements under which it sells the finance receivables it originates to financing partners. As of December 31, 2018, the Company sells finance receivables under multiple agreements, as described in further detail in Note 7 — Finance Receivable Sale Agreements, that expire in November 2019, subject to each party's rights under the respective agreement. The Company plans to extend or enter into new agreements to sell its finance receivables to financing partners within the next year. Management believes that current working capital and expected continued inventory and capital expenditure financing is sufficient to fund operations for at least one year from the financial statement issuance date.
Use of Estimates	Use of EstimatesThe preparation of these consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. Certain accounting estimates involve significant judgments, assumptions and estimates by management that have a material impact on the carrying value of certain assets and liabilities, disclosures of contingent assets and liabilities and the reported amounts of revenues and expenses during the reporting period, which management considers to be critical accounting estimates. The judgments, assumptions and estimates used by management are based on historical experience, management’s experience and other factors, which are believed to be reasonable under the circumstances. Because of the nature of the judgments and assumptions made by management, actual results could differ materially from these judgments and estimates, which could have a material impact on the carrying values of the Company’s assets and liabilities and the results of operations.
Comprehensive Loss	Comprehensive Loss During the years ended December 31, 2018, 2017 and 2016, the Company did not have any other comprehensive income and, therefore, the net loss and comprehensive loss were the same for all periods presented.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company has cash deposits and cash equivalents deposited in or managed by major financial institutions. Cash equivalents include highly liquid investment instruments with original maturities of three months or less, and consist primarily of money market funds. At times the related amounts are in excess of the amounts insured by the Federal Deposit Insurance Corporation. The Company has not experienced any losses with these financial institutions and does not believe it represents significant credit risk.
Restricted Cash	Restricted CashThe restricted cash includes the deposit required under the Company's Floor Plan Facility, which is 5% of the outstanding floor plan facility principal balance, as explained in Note 8 — Debt Instruments and, in previous periods, amounts held as restricted cash as required under letter of credit agreements, as explained in Note 14 — Commitments and Contingencies.
Accounts Receivable, Net	Accounts Receivable, NetAccounts receivable, net of an allowance for doubtful accounts, includes certain amounts due from customers and their finance providers. The allowance for doubtful accounts is estimated based upon historical experience, current economic conditions and other factors and is evaluated periodically.
Finance Receivables Held for Sale, Net	Finance Receivables Held for Sale, Net Finance receivables include installment contracts the Company originates to its customers to facilitate vehicle sales. The Company classifies these receivables as held for sale, as it does not intend to hold the finance receivables it originates to maturity. The Company typically sells the finance receivables it originates, as explained in Note 7 — Finance Receivable Sale Agreements. The Company records a valuation allowance to report finance receivables at the lower of unpaid principal balance or fair value. To determine the fair value of finance receivables the Company utilizes industry-standard modeling, such as discounted cash flow analysis, factoring in the Company’s historical experience, the credit quality of the underlying receivables, loss trends and recovery rates, as well as the overall economic environment. For purposes of determining the valuation allowance, finance receivables are evaluated collectively to determine the allowance as they represent a large group of smaller-balance homogeneous loans. The allowance was approximately $1.8 million and $0.9 million as of December 31, 2018 and 2017, respectively. Principal balances of finance receivables are charged-off when the Company is unable to sell the finance receivable and the related vehicle has been repossessed and liquidated or the receivable has otherwise been deemed uncollectible. The Company has made certain representations related to the sales of finance receivables. Any significant estimated post-sale obligations or contingent obligations to the purchaser of the receivables would be accrued if probable and estimable in accordance with ASC 450, Contingencies . Any such obligations are considered in the Company's determination of the accounting for the transfers of the finance receivables under ASC Topic 860, Transfers and Servicing of Financial Assets.
Vehicle Inventory	Vehicle Inventory Vehicle inventory consists of used vehicles, primarily acquired at auction. Direct and indirect vehicle reconditioning costs including parts and labor, inbound transportation costs and other incremental overhead costs are capitalized as a component of inventory. Inventory is stated at the lower of cost or net realizable value. Vehicle inventory cost is determined by specific identification. Net realizable value is the estimated selling price less costs to complete, dispose and transport the vehicles. Selling prices are derived from historical data and trends, such as sales price and inventory turn times of similar vehicles, as well as independent market resources. Each reporting period the Company recognizes any necessary adjustments to reflect
Property and Equipment	Property and Equipment Property and equipment consists of land, buildings and improvements, transportation fleet equipment, software and furniture, fixtures and equipment and is stated at cost less accumulated depreciation and amortization. Repairs and maintenance costs that extend the life or utility of an asset are also capitalized. Ordinary repairs and maintenance are charged to expense as incurred. Costs incurred during construction are capitalized as construction in progress and reclassified to the appropriate fixed asset categories when the project is completed. In addition, interest on borrowings during the active construction period of construction projects is capitalized and depreciated over the estimated useful lives of the related assets. Costs incurred during the preliminary project planning phase are charged to expense as incurred. The Company capitalizes direct costs of materials and services consumed in developing or obtaining internal-use software. The Company also capitalizes payroll and payroll-related costs for employees who are directly associated with and who devote time to the development of software products for internal use, to the extent of the time spent directly on the project. Capitalization of costs begins during the application development stage and ends when the software is available for general use. Costs incurred during the preliminary project and post-implementation stages are charged to expense as incurred. Depreciation and amortization are computed using the straight-line method over the lesser of the remaining lease term or the following estimated useful lives: Buildings and improvements 5-30 years Transportation fleet equipment 3-8 years Software 3 years Furniture, fixtures and equipment 3-5 years
Goodwill and Intangible Assets	Goodwill and Intangible Assets Intangible assets are recognized and recorded at their acquisition date fair values. Definite-lived intangible assets consist of developed technology, customer relationships and non-compete agreements and are amortized on a straight-line basis over their estimated useful lives . The Company determined the useful lives of its definite-lived intangible assets based on multiple factors including technological obsolescence, the make-up of the acquired customer base and expected attrition, and the period over which expected cash flows are used to measure the fair value of the intangible asset at acquisition. The Company periodically reassesses the useful lives of its definite-lived intangible assets when events or circumstances indicate that useful lives have significantly changed from the previous estimate. Definite-lived intangible assets are tested at least annually or more frequently when events or changes in circumstances indicate that the carrying value may not be recoverable. No impairment charges related to intangible assets were recognized during the years ended December 31, 2018, 2017 or 2016. Goodwill represents the excess purchase price over the fair value of the net assets acquired. Goodwill is not amortized but is tested at least annually or more frequently when events or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company has one operating segment, which is its reporting unit; therefore, management analyzes goodwill associated with all of its operations when analyzing for potential impairment. The Company first assesses qualitative factors to determine if it is not more likely than not that the fair value of its reporting unit is less than its carrying amount. No impairment charges related to goodwill were recognized during the years ended December 31, 2018, 2017 or 2016.
Finance Leases	Finance LeasesThe Company finances certain purchases and construction of its property and equipment through various sale-and-leaseback transactions that do not qualify for sale accounting due to forms of continuing involvement. Accordingly, the Company records the assets subject to these transactions within property and equipment and the sales proceeds as finance leases within long-term debt in the accompanying consolidated balance sheets. Required monthly payments, less the portion considered to be interest expense, reduce the corresponding liabilities.
Revenue Recognition	Revenue Recognition The Company adopted ASC 606, Revenue from Contracts with Customers on January 1, 2018 using the modified retrospective method. ASC 606 prescribes a five-step model that includes: (1) identify the contract; (2) identify the performance obligations; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations; and (5) recognize revenue when (or as) performance obligations are satisfied. Based on the manner in which the Company historically recognized revenue, the adoption of ASC 606 did not have a material impact on the amount or timing of its revenue recognition and the Company recognized no cumulative effect adjustment upon adoption. Used Vehicle Sales The Company sells used vehicles directly to its customers through its website. The prices of used vehicles are set forth in the customer contracts at stand-alone selling prices which are agreed upon prior to delivery. The Company satisfies its performance obligation for used vehicle sales upon delivery when the transfer of title, risks and rewards of ownership and control pass to the customer. The Company recognizes revenue at the agreed upon purchase price stated in the contract, including any delivery charges, less an estimate for returns. Estimates for returns are based on an analysis of historical experience, trends and sales data. Changes in these estimates are reflected as an adjustment to revenue in the period identified. The amount of consideration received for used vehicle sales includes noncash consideration representing the value of trade-in vehicles, if applicable, as stated in the contract. Prior to the delivery of the vehicle, the payment is received or financing has been arranged. Payments from customers that finance their purchases with third parties are typically due and collected within 30 days of delivery of the used vehicle. Revenue excludes any sales taxes, title and registration fees, and other government fees that are collected from customers. Wholesale Vehicle Sales The Company sells vehicles to wholesalers. These vehicles sold to wholesalers are primarily acquired from customers that do not meet the Company’s quality standards to list and sell through its website. The Company satisfies its performance obligation for wholesale vehicle sales when the wholesale purchaser obtains control of the underlying vehicle, which is upon delivery when the transfer of title, risks and rewards of ownership and control pass to the customer. The Company recognizes revenue at the amount it expects to receive for the used vehicle, which is the fixed price determined at the auction. The purchase price of the wholesale vehicle is typically due and collected within 30 days of delivery of the wholesale vehicle. Other Sales and Revenues Other sales and revenues include gains on the sales of finance receivables, commissions on vehicle service contracts ("VSCs"), GAP waiver coverage, and interest income received on finance receivables prior to selling them to investors. Customers purchasing used vehicles from the Company may enter into contracts for VSCs. The Company sells and receives a commission on VSCs under a master dealer agreement with DriveTime, pursuant to which the Company sells VSCs that DriveTime administers and is the obligor. The Company recognizes commission revenue at the time of sale, net of a reserve for estimated contract cancellations. The reserve for cancellations is estimated based upon historical experience and recent trends and is reflected as a reduction of other sales and revenues. Changes in these estimates are reflected as an adjustment to revenue in the period identified. Under the master dealer agreement with DriveTime, the Company is also contractually entitled to receive profit-sharing revenues based on the performance of the VSCs once a required claims period has passed. This is a form of variable consideration the Company recognizes as revenue to the extent that it is probable that it will not result in a significant revenue reversal. The Company applies the expected value method, utilizing expected VSC performance based on historical claims and cancellation data from its customers, as well as other qualitative assumptions to estimate the amount it expects to receive. The Company reassess the estimate each reporting period with any changes reflected as an adjustment to other sales and revenues in the period identified. Profit-sharing payments will begin when the underlying VSCs reach a specified level of claims history. As of December 31, 2018, the Company had recognized approximately $1.9 million related to cumulative profit-sharing payments to which it expects to be entitled, which is included in other assets on the accompanying consolidated balance sheet. Customers that finance their used vehicle purchases with the Company may enter into contracts to purchase GAP waiver coverage, which obligates whoever holds the underlying finance receivable to not attempt collection of a balance that is in excess of the value of the financed vehicle in the event of a total loss. The price of GAP waiver coverage is set forth in each contract. GAP waiver coverage is recognized as the performance obligation is satisfied over the period of coverage, generally on a straight-line basis over the expected period the outstanding balance of the related finance receivable will exceed the value of the financed vehicle, less a reserve for cancellations. The reserve for cancellations is estimated based upon historical experience and recent trends and is reflected as a reduction of other sales and revenues. Changes in these estimates are reflected as an adjustment to other sales and revenues in the period identified. Upon selling the corresponding finance receivable, the Company recognizes any remaining deferred revenue. DriveTime administers a portion of the GAP waiver coverage contracts the Company sells to its customers. The Company also periodically arranges refinancing for its financing partners and earns a fee for structuring and participating the transaction, which it recognizes upon completion. The Company accounts for sales of finance receivables in accordance with ASC Topic 860, Transfers and Servicing of Financial Assets ("ASC 860"). ASC 860 states that a transfer of an entire financial asset, a group of entire financial assets, or a participating interest in an entire financial asset in which the transferor surrenders control over those financial assets is accounted for as a sale only if all of the following conditions are met: • The transferred financial assets have been isolated from the transferor - put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership. • Each transferee has the right to pledge or exchange the assets (or beneficial interests) it received, and no condition both constrains the transferee (or third-party holder of its beneficial interests) from taking advantage of its right to pledge or exchange the asset and provides more than a trivial benefit to the transferor. • The transferor, its consolidated affiliates included in the financial statements being presented or its agents do not maintain effective control over the transferred financial assets or third-party beneficial interests related to those transferred assets.
Cost of Sales	Cost of Sales Cost of sales includes the cost to acquire used vehicles and direct and indirect vehicle reconditioning costs associated with preparing the vehicles for resale. Vehicle reconditioning costs include parts, labor, inbound transportation costs and other incremental overhead costs, which are allocated to inventory via specific identification and standard costing. Occupancy and labor costs not related to vehicle acquisition or reconditioning, including those incurred in connection with expanding production capacity, are expensed as incurred as a component of selling, general and administrative expense. Cost of sales also includes any necessary adjustments to reflect vehicle inventory at the lower of cost or net realizable value.
Selling, General and Administrative Expenses	Selling, General and Administrative Expenses Selling, general and administrative ("SG&A") expenses primarily include compensation and benefits, advertising, depreciation expense, facilities costs, technology expenses, logistics and fulfillment expenses and other administrative expenses. SG&A expenses exclude the costs related to reconditioning vehicles and inbound transportation, which are included in cost of sales, and payroll costs of employees related to the development of software products for internal use, which are capitalized to software and depreciated over the estimated useful lives of the related assets.
Advertising Costs	Advertising CostsAdvertising production costs are expensed the first time the advertising takes place. All other advertising costs are expensed as incurred. Advertising expenses are included in SG&A expenses on the accompanying consolidated statements of operations.
Equity-Based Compensation	Equity-Based CompensationThe Company classifies equity-based awards granted in exchange for services as either equity awards or liability awards. The classification of an award as either an equity award or a liability award is generally based upon cash settlement options. Equity awards are measured based on the fair value of the award at the grant date. Liability awards are re-measured to fair value each reporting period. Each reporting period, the Company recognizes the change in fair value of awards issued to non-employees as expense. The Company recognizes equity-based compensation on a straight-line basis over the award’s requisite service period, which is generally the vesting period of the award, less actual forfeitures. No compensation expense is recognized for awards for which participants do not render the requisite services. For equity and liability awards earned based on performance or upon occurrence of a contingent event, when and if the awards will be earned is estimated. If an award is not considered probable of being earned, no amount of equity-based compensation is recognized. If the award is deemed probable of being earned, related compensation expense is recorded over the estimated service period. To the extent the estimate of awards considered probable of being earned changes, the amount of equity-based compensation recognized will also change.
Shipping and Handling Fees and Costs	Shipping and HandlingThe Company's logistics costs related to transporting its used vehicle inventory include fuel, maintenance and depreciation related to operating its own transportation fleet and third party transportation fees. The portion of these costs related to inbound transportation from the point of acquisition to the inspection and reconditioning center is included in cost of sales when the related used vehicle is sold.
Defined Contribution Plan	Defined Contribution Plan The Company sponsors a qualified 401(k) retirement plan (defined contribution plan) for its employees. The plan covers substantially all employees who have attained the age of 18. Participants may voluntarily contribute to the plan up to the maximum limits established by Internal Revenue Service regulations. The Company provides matching contributions of 40% up to the first 6% of an employee’s compensation, which vests evenly over the employee’s initial five
Fair Value Measurements	Fair Value Measurements The fair value of financial instruments is based on estimates using quoted market prices, discounted cash flows or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and the estimated timing and amount of future cash flows. Therefore, the estimates of fair value may differ substantially from amounts that ultimately may be realized or paid at settlement or maturity of the financial instruments, and those differences may be material. Accordingly, the aggregate fair value amounts presented may not represent the Company’s underlying institutional value.
Segments	Segments Business segments are defined as components of an enterprise about which discrete financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing operating performance. Based on the way the Company manages its business, the Company has determined that it currently operates with one reportable segment. The chief operating decision maker focuses on consolidated results in assessing operating performance and allocating resources. Furthermore, the Company offers similar products and services and uses similar processes to sell those products and services to similar classes of customers throughout the United States ("U.S."). Substantially all revenue is generated and all assets are held in the U.S. for all periods presented.
Income Taxes	Income Taxes The Company accounts for income taxes pursuant to the asset and liability method, which requires the recognition of deferred income tax assets and liabilities related to the expected future tax consequences arising from temporary differences between the carrying amounts and tax bases of assets and liabilities based on enacted statutory tax rates applicable to the periods in which the temporary differences are expected to reverse. Any effects of changes in income tax rates or laws are included in income tax expense in the period of enactment. The Company reduces the carrying amounts of deferred tax assets by a valuation allowance if, based on the evidence available, it is more likely than not that such assets will not be realized. In making the assessment under the more likely than not standard, appropriate consideration must be given to all positive and negative evidence related to the realization of the deferred tax assets. The assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of statutory carry forward periods by jurisdiction, the Company's experience with loss carryforwards not expiring unutilized and all tax planning alternatives that may be available. A valuation allowance is recognized if under applicable accounting standards the Company
Adoption of New Accounting Standards and Accounting Standards Issued But Not Yet Adopted	Adoption of New Accounting Standards As discussed above, the Company adopted ASC 606 on January 1, 2018 using the modified retrospective method. ASC 606 requires the reserve for vehicle inventory returns to be presented separately from vehicle inventory, where the Company previously presented it. As of December 31, 2017, the reserve for estimated returns included within vehicle inventory was approximately $2.6 million. As of December 31, 2018 , the reserve for estimated returns included within other current assets was approximately $5.3 million. Furthermore, based on the manner in which the Company recognizes revenue, the adoption of ASC 606 did not have a material impact on the amount or timing of its revenue recognition and the Company recognized no cumulative effect adjustment upon adoption. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows — Classification of Certain Receipts and Payments ("ASU 2016-15"), which provides additional clarity on the classification of specific events on the statement of cash flows including debt prepayment and extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds from settlement of insurance claims, distributions received from equity method investees and beneficial interests in securitization transactions. The Company adopted this ASU on January 1, 2018. The adoption of ASU 2016-15 did not have a material effect on its consolidated statements of cash flows. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows — Restricted Cash ("ASU 2016-18"), which requires the statement of cash flows to include restricted cash with its cash and cash equivalents balance and a reconciliation between all cash items on the balance sheet and the balance presented in the statement of cash flows. In addition, changes in restricted cash related to transfers between cash and cash equivalents and restricted cash will not be presented as cash flow activities in the statement of cash flows. The Company adopted ASU 2016-18 on January 1, 2018 on a retrospective basis. As a result, changes in restricted cash are no longer presented as investing cash flow activities and the restricted cash balance is included with cash and cash equivalents in the beginning and end of period balances on the Company's consolidated statements of cash flows for all periods presented. For the years ended December 31, 2017 and 2016, changes in restricted cash included within cash used in investing activities, as originally presented, were approximately $4.2 million and $8.2 million, respectively. In January 2017, the FASB issued ASU 2017-04, Intangibles — Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"), which is intended to simplify the goodwill impairment test by eliminating the second step of the goodwill impairment test, which requires performing a hypothetical purchase price allocation. Under ASU 2017-04, goodwill impairment should be recognized based on the amount by which a reporting unit's carrying amount exceeds its fair value, but should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019, may be early adopted after January 1, 2017, and should be applied on a prospective basis. The Company adopted ASU 2017-04 on October 1, 2018 and it did not have a material effect on its consolidated financial statements. Accounting Standards Issued But Not Yet Adopted Since February 2016, the FASB has issued several accounting standards updates related to the new leasing model in ASC 842, Leases ("ASC 842"). ASC 842 introduces a lessee model that requires a right-of-use asset and lease obligation to be presented on the balance sheet for certain leases, whether operating or financing. ASC 842 eliminates the requirement in current U.S. GAAP for an entity to use bright-line tests in determining lease classification. Expense recognition on the income statement remains similar to current lease accounting guidance. ASC 842 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2018 and should be applied using a modified retrospective approach, with the option to elect various practical expedients. The Company will adopt ASC 842 for its interim and fiscal year beginning January 1, 2019. While the Company is still evaluating the full effect this guidance will have on its consolidated financial statements and related disclosures, the Company expects the adoption of ASC 842 will result in recognizing right-of-use assets and lease liabilities for its operating leases of approximately $78.0 million - $88.0 million on its consolidated balance sheets on January 1, 2019. The Company does not expect this standard to have a material impact on its sale-leaseback transactions currently accounted for as financing transactions and believes most of its leases will maintain their current lease classification under the new standard. In June 2016, the FASB issued ASU 2016-13, Financial instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"), which amends the guidance on the impairment of financial instruments by requiring measurement and recognition of expected credit losses for financial assets held. ASU 2016-13 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2019, and earlier adoption is permitted beginning in the first quarter of fiscal 2019. The Company is currently evaluating the impact on its consolidated financial statements, and plans to adopt this ASU for its fiscal year beginning January 1, 2020. Finance receivables originated in connection with the Company’s vehicle sales are held for sale and are subsequently sold. The Company does not presently hold any finance receivables until maturity and therefore does not expect adoption of ASU 2016-13 to have a material impact on its consolidated financial statements. In June 2018, the FASB issued ASU 2018-07, Compensation — Stock Compensation (Topic 718) ("ASU 2018-07") related to the accounting for share-based payment transactions for acquiring goods and services from nonemployees. Under ASU 2018-07, the intent is to simplify and align most requirements for share-based payments to nonemployees with the requirements for share-based payments granted to employees under ASC 718, including measuring the equity instruments at the grant-date fair value. ASU 2018-07 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2018, and will be applied on a modified retrospective basis through a cumulative-effect adjustment to accumulated deficit. The Company will adopt ASU 2018-07 for interim and annual periods beginning on January 1, 2019 and does not expect it to have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement ("ASU 2018-13") related to updated requirements over the disclosures of fair value measurements. Under ASU 2018-13, certain disclosure requirements for fair value measurements will be eliminated, modified or added to facilitate better communication around recurring and nonrecurring fair value measurements. ASU 2018-13 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2019, with some amendments applied prospectively, some applied retrospectively and early adoption permitted. The Company plans to adopt ASU 2018-13 for its fiscal year beginning January 1, 2020 and is currently assessing the impact the guidance will have on its consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract ("ASU 2018-15"). The intent of this pronouncement is to align the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software as defined in ASC 350-40. Under ASU 2018-15, the capitalized implementation costs related to a cloud computing arrangement will be amortized over the term of the arrangement and all capitalized implementation amounts will be required to be presented in the same line items of the financial statements as the related hosting fees. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. The Company plans to adopt ASU 2018-15 for its fiscal year beginning January 1, 2020 and is currently assessing the impact, if any, the guidance will have on its consolidated financial statements. In October 2018, the FASB issued ASU 2018-17, Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities ("ASU 2018-17"). ASU 2018-17 requires reporting entities to consider indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety for determining whether a decision-making fee is a variable interest. The standard is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. Entities are required to apply the amendments in ASU 2018-17 retrospectively with a cumulative-effect adjustment to retained earnings at the beginning of the earliest period presented. The Company is currently assessing the impact, if any, the guidance will have on its consolidated financial statements.
Loss Per Share	Basic and diluted net loss per share is computed by dividing the net loss attributable to Class A common stockholders by the weighted-average shares of Class A common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potentially dilutive shares. For all periods presented, potentially dilutive shares are excluded from diluted net loss per share because they have an anti-dilutive impact. Therefore, basic and diluted net loss per share attributable to Class A common stockholders are the same for all periods presented. As discussed in Note 1 — Business Organization, the Organizational Transactions are considered transactions between entities under common control and the financial statements for periods prior to the IPO and Organizational Transactions have been adjusted to combine the previously separate entities for presentation purposes. For purposes of calculating both the numerator and denominator of net loss per share for periods prior to the IPO, the Company has retroactively reflected the 15.0 million shares issued in the IPO and the LLC Units outstanding as of the Organizational Transactions as if they had been issued and outstanding as of the beginning of each period presented. These calculations for periods prior to the IPO do not consider the options or shares of Class A common stock issued on the IPO date under the 2017 Incentive Plan.

Schedule of Common Units	—
Schedule of Share-based Payment Award, Stock, Common Units, Valuation Assumptions	The Company used a third party valuation specialist to assist management in its estimation of the grant-date fair value of the Class B Units on the respective grant dates during 2016 and 2017. There were no Class B Units granted in 2018. As the participation threshold provides a threshold similar to that of an exercise price for a stock option, the Company used option pricing valuation models with the following weighted-average assumptions: 2017 2016 Expected volatility (1) 63.0 % 68.0 % Expected dividend yield — % — % Expected term (in years) (2) 6.3 1.8 Risk-free interest rate 1.9 % 0.9 % Weighted-average grant date fair value per Class B Unit $ 7.04 $ 0.34 (1) Measured using selected high-growth guideline companies and considering the risk factors that would influence the range of expected volatility because the Company does not have sufficient historical data to provide a reasonable basis upon which to estimate the expected volatility. (2) In 2017, the expected term represents the estimated period of time until an award is exchanged and was determined using the simplified method because the Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term.
