[1]	1) Net of accumulated impairment of $97.8 million.The Company evaluates intangible franchise rights and goodwill assets for impairment annually or more frequently if events or circumstances indicate possible impairment. During the three months ended September 30, 2017, the Company identified circumstances indicating possible impairment of some individual franchise rights, requiring a quantitative assessment. The Company did not identify any such circumstances relative to the goodwill for each of its reporting units. Based on the results of the Company's assessment, the Company determined that the fair value of the franchise rights on one of its U.S. dealerships was below its respective carrying value, resulting in franchise asset impairment charges of $9.5 million. This was recognized as an asset impairment in the Company's Consolidated Statements of Operations during the three months ended September 30, 2017.

Interim Financial Information

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Interim Financial Information	INTERIM FINANCIAL INFORMATION Business and Organization Group 1 Automotive, Inc., a Delaware corporation, is a leading operator in the automotive retailing industry with business activities in 15 states in the United States of America ("U.S."), 28 towns in the United Kingdom ("U.K.") and four states in Brazil. Group 1 Automotive, Inc. and its subsidiaries are collectively referred to as the "Company" in these Notes to Consolidated Financial Statements. The Company, through its regions, sells new and used cars and light trucks; arranges related vehicle financing; sells service and insurance contracts; provides automotive maintenance and repair services; and sells vehicle parts. As of September 30, 2017 , the Company’s U.S. retail network consisted of 115 dealerships within the following states: Alabama, California, Florida, Georgia, Kansas, Louisiana, Maryland, Massachusetts, Mississippi, New Hampshire, New Jersey, New Mexico, Oklahoma, South Carolina, and Texas. The President of U.S. Operations reports directly to the Company's Chief Executive Officer and is responsible for the overall performance of the U.S. region, as well as for overseeing the market directors and dealership general managers. In addition, as of September 30, 2017 , the Company had two international regions: (a) the U.K., which consisted of 43 dealerships and (b) Brazil, which consisted of 16 dealerships. The operations of the Company's international regions are structured similar to the U.S. region, each with a regional vice president reporting directly to the Company's Chief Executive Officer. The Company's operating results are generally subject to seasonal variations, as well as changes in the economic environment. This seasonality is generally attributable to consumer buying trends and the timing of manufacturer new vehicle model introductions. In addition, in some regions of the U.S., vehicle purchases decline during the winter months due to inclement weather. As a result, U.S. revenues and operating income are typically lower in the first and fourth quarters and higher in the second and third quarters. For the U.K., the first and third quarters tend to be stronger, driven by the vehicle license plate change months of March and September. For Brazil, the Company expects higher volumes in the third and fourth calendar quarters. The first quarter in Brazil is generally the weakest, driven by more consumer vacations and activities associated with Carnival. Other factors unrelated to seasonality, such as changes in economic conditions, manufacturer incentive programs, severe weather events and changes in current exchange rates may exaggerate seasonal or cause counter-seasonal fluctuations in the Company's revenues and operating income. Basis of Presentation The accompanying unaudited condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the U.S. ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments of a normal and recurring nature considered necessary for a fair presentation have been included in the accompanying unaudited condensed Consolidated Financial Statements. Due to seasonality and other factors, the results of operations for the interim period are not necessarily indicative of the results that will be realized for any other interim period or for the entire fiscal year. For further information, refer to the Consolidated Financial Statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 (“ 2016 Form 10-K”). All business acquisitions completed during the periods presented have been accounted for using the purchase method of accounting, and their results of operations are included from the effective dates of the closings of the acquisitions. The allocations of purchase price to the assets acquired and liabilities assumed are assigned and recorded based on estimates of fair value and are subject to change within the purchase price allocation period (generally one year from the respective acquisition date). All intercompany balances and transactions have been eliminated in consolidation. Business Segment Information The Company has three reportable segments: the U.S., which includes the activities of the Company's corporate office, the U.K. and Brazil. The reportable segments are the business activities of the Company for which discrete financial information is available and for which operating results are regularly reviewed by its chief operating decision maker to allocate resources and assess performance. The Company's chief operating decision maker is its Chief Executive Officer. See Note 14, "Segment Information," for additional details regarding the Company's reportable segments. Recently Adopted Accounting Pronouncements In July 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. The amendments in the accounting standard replaced the lower of cost or market test with a lower of cost and net realizable value test. The amendments in this ASU were to be applied prospectively and were effective for interim and annual periods beginning after December 15, 2016. The Company adopted ASU 2015-11 during the first quarter of 2017. The adoption of this ASU did not materially impact its consolidated financial statements or results of operations. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amendment addresses several aspects of the accounting for share-based payment award transactions, including: income tax consequences; classification of awards as either equity or liabilities; and classification on the statement of cash flows. The Company adopted ASU 2016-09 during the first quarter of 2017. The adoption of this ASU did not materially impact its consolidated financial statements or results of operations. Recently Issued Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) that amends the accounting guidance on revenue recognition. The amendments in this ASU are intended to provide a framework for addressing revenue issues, improve comparability of revenue recognition practices, and improve disclosure requirements. This ASU sets forth a five-step model for determining when and how revenue is recognized. Under the model, an entity will be required to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. The amendments in this accounting standard update are effective for interim and annual reporting periods beginning after December 15, 2017. The standard can be adopted either retrospectively to each reporting period presented or as a cumulative effect adjustment as of the date of adoption. To assess the impact of the ASU, the Company established an internal implementation team to review its current accounting policies and practices, identify all material revenue streams, assess the impact of the ASU on its material revenue streams and identify potential differences with current policies and practices. The team has identified the Company’s material revenue streams to be the sale of new and used vehicles; arrangement of associated vehicle financing; the sale of service and insurance contracts; the performance of vehicle maintenance and repair services; and the sale of vehicle parts. The team has reviewed a sample of contracts and other related documents associated with each revenue stream. The team does not anticipate any changes to the timing of revenue recognition for the sale of new and used vehicles. The team is currently evaluating the constraint factors for a portion of the transaction price for certain service and insurance contracts. The new standard requires that an estimate of variable consideration, subject to a constraint, be included in the transaction price and recognized when or as the performance obligation is satisfied. In the event variable consideration is considered fully constrained, recognition will occur once the uncertainties associated with the constraint are determined to be resolved. However, in the event the team's evaluation determines the variable consideration is not fully constrained, revenue would be subject to accelerated recognition under the new standard. As it relates to vehicle maintenance and repair services, the Company currently recognizes revenue once the repair service is completed. The team is currently assessing whether revenue will be recognized over time as the services are performed, under the new standard. The Company’s implementation team is in the final stages of evaluating the additional disclosure requirements of the ASU, as well as the change, if any, to the Company’s underlying accounting and financial reporting systems and processes necessary to support the recognition and disclosure requirements. The Company expects to identify and implement the necessary changes, if any, during the fourth quarter of 2017. At this time, based on this review, the Company does not expect the adoption to materially impact its consolidated financial statements. The Company will adopt the amendments of this ASU during the first fiscal quarter of 2018, using the modified retrospective approach with a cumulative effect adjustment as of the date of adoption. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The amendments in this ASU relate to the accounting for leasing transactions. This standard requires a lessee to record on the balance sheet the assets and liabilities for the rights and obligations created by leases with lease terms of more than 12 months. In addition, this standard requires both lessees and lessors to disclose certain key information about lease transactions. This standard will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is in the process of evaluating the impact that adoption will have on its consolidated balance sheet and statement of income. However, the Company expects that the adoption of the provisions of the ASU will have a significant impact on its consolidated balance sheet, as currently approximately half of its real estate is rented, not owned, via operating leases. Adoption of this ASU is required to be done using a modified retrospective approach. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments . The amendment replaces the current incurred loss impairment methodology of recognizing credit losses when a loss is probable, with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to assess credit loss estimates. The standard will be effective for fiscal years beginning after December 15, 2019, with early adoption permitted for periods after December 15, 2018. The Company is currently evaluating the impact that the adoption of the provisions of the ASU will have on its consolidated financial statements or results of operations, but does not expect the amendments in this ASU to materially impact its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The amendment addresses several specific cash flow issues with the objective of reducing the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The standard will be effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of the provisions of the ASU will have on its consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, a consensus of the FASB Emerging Issues Task Force ("EITF") . The amendments require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this ASU do not provide a definition of restricted cash or restricted cash equivalents. The standard will be effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of the provisions of the ASU will have on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business . The amendments in this update clarify the definition of a business in order to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in this ASU should be applied prospectively and are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact on its consolidated financial statements as it will depend on the facts and circumstances of any specific future transactions. In January 2017, the FASB issued ASU 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments-Equity Method and Joint Ventures (Topic 323): Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 17, 2016 EITF Meetings . The amendments in this update require the disclosure of the impact that a recently issued ASU will have on the financial statements of a registrant when such standards are to be adopted in a future period. The SEC staff views that a registrant should evaluate ASU's that have not yet been adopted to determine the appropriate financial statement disclosures about the potential material effects of those ASU's on the financial statements when adopted. The Company does not expect the amendments in this ASU to materially impact its consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . The amendment eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit's carrying amount over its fair value. The amendments in this update should be applied prospectively and are effective for interim and annual periods beginning after December 15, 2019. Earlier application is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact that the adoption of the provisions of the ASU will have on its consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting . The amendments in this update provide clarity and reduce both diversity in practice and cost and complexity when applying the guidance of Topic 718 to a change to the terms or conditions of a share-based payment award. Under the new guidance, an entity will not apply modification accounting to a share-based payment award if all of the following are the same immediately before and after the change: 1) the award's fair value (or calculated value or intrinsic value, if those measurement methods are used), 2) the award's vesting conditions, and 3) the award's classification as an equity or liability instrument. The amendments in this ASU should be applied prospectively and are effective for fiscal years beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the impact on its consolidated financial statements as it will depend on the facts and circumstances of any specific future transactions. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 715): Targeted Improvements to Accounting for Hedging Activities. The amendments in this update better align an entity's risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The guidance also eases the administrative burden of hedge documentation requirements and assessing hedge effectiveness. The amendments to cash flow and net investment hedge relationships should be applied using a modified retrospective approach while the presentation and disclosure requirements are applied prospectively, effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact that the adoption of the provisions of the ASU will have on its consolidated financial statements.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS AND RISK MANAGEMENT ACTIVITIES	DERIVATIVE INSTRUMENTS AND RISK MANAGEMENT ACTIVITIES The periodic interest rates of the Revolving Credit Facility (as defined in Note 8, “Credit Facilities”) and certain variable-rate real estate related borrowings in the U.S. are indexed to the one-month London Inter Bank Offered Rate (“LIBOR”), plus an associated company credit risk rate. In order to minimize the earnings variability related to fluctuations in these periodic interest rates, the Company employs an interest rate hedging strategy, whereby it enters into arrangements with various financial institutional counterparties with investment grade credit ratings, swapping its variable interest rate exposure for a fixed interest rate over terms not to exceed the related variable-rate debt. The Company presents the fair value of all interest rate derivative instruments on its Consolidated Balance Sheets. The Company measures the fair value of its interest rate derivative instruments utilizing an income approach valuation technique, converting future amounts of cash flows to a single present value in order to obtain a transfer exit price within the bid and ask spread that is most representative of the fair value of its derivative instruments. In measuring fair value, the Company utilizes the option-pricing Black-Scholes present value technique for all of its derivative instruments. This option-pricing technique utilizes a one-month LIBOR forward yield curve, obtained from an independent external service provider, matched to the identical maturity term of the instrument being measured. Observable inputs utilized in the income approach valuation technique incorporate identical contractual notional amounts, fixed coupon rates, periodic terms for interest payments and contract maturity. The fair value estimate of the interest rate derivative instruments also considers the credit risk of the Company for instruments in a liability position or the counterparty for instruments in an asset position. The credit risk is calculated by using the spread between the one-month LIBOR yield curve and the relevant average 10 and 20-year rate according to Standard and Poor’s. The Company has determined the valuation measurement inputs of these derivative instruments to maximize the use of observable inputs that market participants would use in pricing similar or identical instruments and market data obtained from independent sources, which is readily observable or can be corroborated by observable market data for substantially the full term of the derivative instrument. Further, the valuation measurement inputs minimize the use of unobservable inputs. Accordingly, the Company has classified the derivatives within Level 2 of the hierarchy framework as described by Accounting Standards Codification ("ASC") 820, Fair Value Measurement . The related gains or losses on these interest rate derivative instruments are deferred in stockholders’ equity as a component of accumulated other comprehensive loss. These deferred gains and losses are recognized in income in the period in which the related items being hedged are recognized in expense. However, to the extent that the change in value of a derivative contract does not perfectly offset the change in the value of the items being hedged, that ineffective portion is immediately recognized in other income or expense. Monthly contractual settlements of these swap positions are recognized as floorplan or other interest expense in the Company’s accompanying Consolidated Statements of Operations. All of the Company’s interest rate derivative instruments are designated as cash flow hedges. As of September 30, 2017 , all of the Company’s derivative instruments that were in effect were determined to be effective. The Company had no gains or losses related to ineffectiveness or amounts excluded from effectiveness testing recognized in the Consolidated Statements of Operations for both the three and nine months ended September 30, 2017 or 2016 , respectively. The Company held interest rate derivative instruments in effect as of September 30, 2017 of $823.9 million in notional value that fixed its underlying one-month LIBOR at a weighted average rate of 2.5% . The Company records the majority of the impact of the periodic settlemen ts of these swaps as a component of floorplan interest expense. For the three months ended September 30, 2017 and 2016 , the impact of the Company’s interest rate hedges in effect increased floorplan interest expense by $2.3 million and $2.8 million , respectively. For the nine months ended September 30, 2017 and 2016 , the impact of the Company’s interest rate hedges in effect increased floorplan interest expense by $8.0 million and $8.4 million , respectively. Total floorplan interest expense, inclusive of the aforementioned impact of the Company's interest rate hedges, was $13.5 million and $11.1 million for the three months ended September 30, 2017 and 2016 , respectively, and $38.7 million and $33.7 million for the nine months ended September 30, 2017 and 2016 , respectively. In addition to the $823.9 million of swaps in effect as of September 30, 2017 , the Company held 12 additional interest rate derivative instruments with forward start dates between December 2017 and December 2020 and expiration dates between December 2020 and December 2030 . The aggregate notional value of these 12 forward-starting swaps was $625.0 million , and the weighted average interest rate was 2.2% . The combination of the interest rate derivative instruments currently in effect and these forward-starting derivative instruments is structured such that the notional value in effect at any given time through December 2030 does not exceed $918.4 million , which is less than the Company's expectation for variable-rate debt outstanding during such period. As of September 30, 2017 and December 31, 2016 , the Company reflected liabilities from interest rate risk management activities of $17.0 million and $24.4 million , respectively, in its Consolidated Balance Sheets. In addition, as of September 30, 2017 and December 31, 2016, the Company reflected $7.7 million and $9.5 million , respectively, of assets from interest rate risk management activities in Other Assets in the Consolidated Balance Sheets. Included in Accumulated Other Comprehensive Loss at September 30, 2017 and 2016 were accumulated unrealized losses, net of income taxes, totaling $5.8 million and $28.7 million , respectively, related to these interest rate derivative instruments. The following table presents the impact during the current and comparative prior year periods for the Company's interest rate derivative instruments on its Consolidated Statements of Operations and Consolidated Balance Sheets .

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION PLANS	STOCK-BASED COMPENSATION PLANS The Company provides stock-based compensation benefits to employees and non-employee directors pursuant to its 2014 Long Term Incentive Plan (the "Incentive Plan"), as well as to employees pursuant to its Employee Stock Purchase Plan, as amended (the "Purchase Plan", formerly named the 1998 Employee Stock Purchase Plan). 2014 Long Term Incentive Plan The Incentive Plan provides for the grant of options (including options qualified as incentive stock options under the Internal Revenue Code of 1986 and options that are non-qualified), restricted stock, performance awards, bonus stock, and phantom stock to the Company's employees, consultants, non-employee directors and officers. The Incentive Plan expires on May 21, 2024 . The terms of the awards (including vesting schedules) are established by the Compensation Committee of the Company’s Board of Directors. As of September 30, 2017 , there were 1,074,695 shares available for issuance under the Incentive Plan. Restricted Stock Awards Under the Incentive Plan, the Company grants to non-employee directors and certain employees restricted stock awards or, at their election, restricted stock units at no cost to the recipient. Restricted stock awards qualify as participating securities as each award contains non-forfeitable rights to dividends. As such, the two-class method is required for the computation of earnings per share. See Note 5, “Earnings Per Share,” for further details. Restricted stock awards are considered outstanding at the date of grant but are subject to vesting periods upon issuance of up to five years . Restricted stock units are considered vested at the time of issuance. However, since they convey no voting rights, they are not considered outstanding when issued. Restricted stock units settle in cash upon the termination of the grantees’ employment or directorship. In the event an employee or non-employee director terminates his or her employment or directorship with the Company prior to the lapse of the restrictions, the shares, in most cases, will be forfeited to the Company. The Company issues new shares or treasury shares, if available, when restricted stock vests. Compensation expense for restricted stock awards is calculated based on the market price of the Company’s common stock at the date of grant and recognized over the requisite service period. Forfeitures are estimated at the time of valuation and reduce expense ratably over the vesting period. This estimate is adjusted annually based on the extent to which actual or expected forfeitures differ from the previous estimate. A summary of the restricted stock awards as of September 30, 2017 , along with the changes during the nine months then ended, is as follows: Awards Weighted Average Grant Date Fair Value Nonvested at December 31, 2016 850,422 $ 67.25 Granted 205,789 75.04 Vested (252,015 ) 70.55 Forfeited (93,818 ) 68.67 Nonvested at September 30, 2017 710,378 $ 68.16 Employee Stock Purchase Plan The Purchase Plan authorizes the issuance of up to 4.5 million shares of common stock and provides that no options to purchase shares may be granted under the Purchase Plan after May 19, 2025 . The Purchase Plan is available to all employees of the Company and its participating subsidiaries and is a qualified plan as defined by Section 423 of the Internal Revenue Code. At the end of each fiscal quarter (the “Option Period”) during the term of the Purchase Plan, employees can acquire shares of common stock from the Company at 85% of the fair market value of the common stock on the first or the last day of the Option Period, whichever is lower. As of September 30, 2017 , there were 1,166,445 shares available for issuance under the Purchase Plan. During the nine months ended September 30, 2017 and 2016 , the Company issued 96,098 and 125,154 shares, respectively, of common stock to employees participating in the Purchase Plan. With respect to shares issued under the Purchase Plan, the Company's Board of Directors has authorized specific share repurchases to fund the shares issuable under the Purchase Plan. The weighted average per share fair value of employee stock purchase rights issued pursuant to the Purchase Plan was $16.69 and $13.05 for the nine months ended September 30, 2017 and 2016 , respectively. The fair value of stock purchase rights is calculated using the grant date stock price, the value of the embedded call option and the value of the embedded put option. Stock-Based Compensation Total stock-based compensation cost was $4.1 million and $4.7 million for the three months ended September 30, 2017 and 2016 , respectively, and $14.6 million and $14.9 million for the nine months ended September 30, 2017 and 2016 , respectively. Cash received from Purchase Plan purchases was $5.5 million and $5.6 million for the nine months ended September 30, 2017 and 2016 , respectively.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE The two-class method is utilized for the computation of the Company's earnings per share (“EPS”). The two-class method requires a portion of net income to be allocated to participating securities, which are unvested awards of share-based payments with non-forfeitable rights to receive dividends or dividend equivalents. The Company’s restricted stock awards are participating securities. Income allocated to these participating securities is excluded from net earnings available to common shares, as shown in the table below. Basic EPS is computed by dividing net income available to basic common shares by the weighted average number of basic common shares outstanding during the period. Diluted EPS is computed by dividing net income available to diluted common shares by the weighted average number of dilutive common shares outstanding during the period. The following table sets forth the calculation of EPS for the three and nine months ended September 30, 2017 and 2016 . Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 (In thousands, except per share amounts) Weighted average basic common shares outstanding 20,222 20,568 20,475 21,355 Dilutive effect of employee stock purchases, net of assumed repurchase of treasury stock 3 10 5 9 Weighted average dilutive common shares outstanding 20,225 20,578 20,480 21,364 Basic: Net Income $ 29,881 $ 35,366 $ 102,953 $ 116,237 Less: Earnings allocated to participating securities 1,024 1,427 3,660 4,652 Earnings available to basic common shares $ 28,857 $ 33,939 $ 99,293 $ 111,585 Basic earnings per common share $ 1.43 $ 1.65 $ 4.85 $ 5.23 Diluted: Net Income $ 29,881 $ 35,366 $ 102,953 $ 116,237 Less: Earnings allocated to participating securities 1,023 1,426 3,659 4,651 Earnings available to diluted common shares $ 28,858 $ 33,940 $ 99,294 $ 111,586 Diluted earnings per common share $ 1.43 $ 1.65 $ 4.85 $ 5.22

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company is subject to U.S. federal income taxes and income taxes in numerous U.S. states. In addition, the Company is subject to income tax in the U.K. and Brazil relative to its foreign subsidiaries. The Company's effective income tax rate of 36.6% for the three months ended September 30, 2017 was more than the U.S. federal statutory rate of 35.0% , due primarily to the taxes provided for in U.S. state jurisdictions, valuation allowances provided for net operating losses and other deferred tax assets in certain U.S. states and in Brazil and unrecognized tax benefits with respect to uncertain tax positions, partially offset by income generated in the U.K., which is taxed at a lower statutory rate. The Company's effective income tax rate of 35.7% of pretax income for the nine months ended September 30, 2017 , was more than the U.S. federal statutory rate of 35.0% , as taxes provided for in the U.S. state jurisdictions and valuation allowances provided for net operating losses and other deferred tax assets in certain U.S. states and in Brazil and unrecognized tax benefits with respect to uncertain tax positions, were substantially offset by (a) income generated in the U.K., which is taxed at a lower statutory rate, (b) the tax impact of dealership dispositions in Brazil, and (c) excess tax deductions for restricted stock resulting from the adoption of ASU 2016-09 during the nine months ended September 30, 2017 . For the three and nine months ended September 30, 2017 , the Company's effective tax rate increased to 36.6% and 35.7% , respectively, as compared to 36.5% and 35.0% for the three and nine months ended September 30, 2016 , respectively. This increase was primarily due to the mix effect resulting from taxes provided for in foreign jurisdictions, changes to valuation allowances provided for net operating losses and other deferred tax assets in certain U.S. states and in Brazil and unrecognized tax benefits with respect to uncertain tax positions during the three and nine months ended September 30, 2017, partially offset by excess tax deductions for restricted stock resulting from the adoption of ASU 2016-09 during the nine months ended September 30, 2017 , as well as the tax impact of dealership dispositions in Brazil during the nine months ended September 30, 2016 . As of September 30, 2017 , the Company recorded $1.2 million unrecognized tax benefits, including $0.2 million of related interest and penalty. As of December 31, 2016 , the Company had no unrecognized tax benefits with respect to uncertain tax positions and did not incur any interest and penalties. Consistent with prior treatment of tax related assessments, the Company recognizes interest and penalties related to uncertain tax positions in income tax expense. The Company's taxable years 2013 and subsequent remain open for examination in the U.S. The Company's taxable years 2015 and subsequent remain open in the U.K. and taxable years 2012 and subsequent remain open in Brazil.

Credit Facilities

Credit Facilities	9 Months Ended

Line of Credit Facility [Abstract]
CREDIT FACILITIES	CREDIT FACILITIES In the U.S., the Company has a $1.8 billion revolving syndicated credit arrangement that matures on June 17, 2021 and is comprised of 24 financial institutions, including six manufacturer-affiliated finance companies (“Revolving Credit Facility”). The Company also has a $300.0 million floorplan financing arrangement (“FMCC Facility”) with Ford Motor Credit Company (“FMCC”) for financing of new Ford vehicles in the U.S. and other floorplan financing arrangements with several other automobile manufacturers for financing of a portion of its U.S. rental vehicle inventory. In the U.K., the Company has financing arrangements with BMW Financial Services NA, LLC ("BMWFS"), Volkswagen Finance, Toyota Motor Credit Corporation, FMCC and a third-party financial institution for financing of its new, used and rental vehicles. In Brazil, the Company has financing arrangements for new, used, and rental vehicles with several financial institutions, most of which are manufacturer affiliated. Within the Company's Consolidated Balance Sheets, Floorplan notes payable - credit facility and other primarily reflects amounts payable for the purchase of specific new, used and rental vehicle inventory (with the exception of new and rental vehicle purchases financed through lenders affiliated with the respective manufacturer) whereby financing is provided by the Revolving Credit Facility. Floorplan notes payable - manufacturer affiliates reflects amounts related to the purchase of vehicles whereby financing is provided by the FMCC Facility, the financing of a portion of the Company's rental vehicles in the U.S., as well as the financing of new, used, and rental vehicles with manufacturer affiliates in both the U.K. and Brazil. Payments on the floorplan notes payable are generally due as the vehicles are sold. As a result, these obligations are reflected in the accompanying Consolidated Balance Sheets as current liabilities. Revolving Credit Facility The Company's Revolving Credit Facility provides a total borrowing capacity of $1.8 billion and expires on June 17, 2021 . The Revolving Credit Facility consists of two tranches, providing a maximum of $1.75 billion for U.S. vehicle inventory floorplan financing (“Floorplan Line”), as well as a maximum of $360.0 million and a minimum of $50.0 million for working capital and general corporate purposes, including acquisitions (“Acquisition Line”). The capacity under these two tranches can be re-designated within the overall $1.8 billion commitment, subject to the aforementioned limits. Up to $125.0 million of the Acquisition Line can be borrowed in either euros or British pound sterling. The Revolving Credit Facility can be expanded to a maximum commitment of $2.1 billion , subject to participating lender approval. The Floorplan Line bears interest at rates equal to the LIBOR plus 125 basis points for new vehicle inventory and the LIBOR plus 150 basis points for used vehicle inventory. The Acquisition Line bears interest at the LIBOR plus 150 basis points plus a margin that ranges from zero to 100 basis points , depending on the Company's total adjusted leverage ratio, for borrowings in U.S. dollars and a LIBOR equivalent plus 125 to 250 basis points , depending on the Company's total adjusted leverage ratio, on borrowings in euros or British pound sterling. The Floorplan Line requires a commitment fee of 0.15% per annum on the unused portion. Amounts borrowed by the Company under the Floorplan Line for specific vehicle inventory are to be repaid upon the sale of the vehicle financed, and in no case is a borrowing for a vehicle to remain outstanding for greater than one year . The Acquisition Line also requires a commitment fee ranging from 0.20% to 0.45% per annum, depending on the Company’s total adjusted leverage ratio, based on a minimum commitment of $50.0 million less outstanding borrowings. In conjunction with the Revolving Credit Facility, the Company has $4.5 million of related unamortized costs as of September 30, 2017 , which are included in Prepaid expenses and other current assets and Other Assets on the accompanying Consolidated Balance Sheets and amortized over the term of the facility. After considering the outstanding balance of $1,017.2 million at September 30, 2017 , the Company had $422.8 million of available floorplan borrowing capacity under the Floorplan Line. Included in the $422.8 million available borrowings under the Floorplan Line was $46.2 million of immediately available funds. The weighted average interest rate on the Floorplan Line was 2.5% and 2.0% as of September 30, 2017 and December 31, 2016 , respectively, excluding the impact of the Company’s interest rate derivative instruments. With regards to the Acquisition Line, there were $33.5 million borrowings outstanding as of September 30, 2017 and no borrowings outstanding as of December 31, 2016 . After considering $29.3 million of outstanding letters of credit and other factors included in the Company’s available borrowing base calculation, there was $297.1 million of available borrowing capacity under the Acquisition Line as of September 30, 2017 . The amount of available borrowing capacity under the Acquisition Line is limited from time to time based upon certain debt covenants. All of the U.S. dealership-owning subsidiaries are co-borrowers under the Revolving Credit Facility. The Company’s obligations under the Revolving Credit Facility are secured by essentially all of the Company's U.S. personal property (other than equity interests in dealership-owning subsidiaries), including all motor vehicle inventory and proceeds from the disposition of dealership-owning subsidiaries, excluding inventory financed directly with manufacturer-affiliates and other third-party financing institutions. The Revolving Credit Facility contains a number of significant covenants that, among other things, restrict the Company’s ability to make disbursements outside of the ordinary course of business, dispose of assets, incur additional indebtedness, create liens on assets, make investments and engage in mergers or consolidations. The Company is also required to comply with specified financial tests and ratios defined in the Revolving Credit Facility, such as the fixed charge coverage and total adjusted leverage ratios. Further, the Revolving Credit Facility restricts the Company’s ability to make certain payments, such as dividends or other distributions of assets, properties, cash, rights, obligations or securities (“Restricted Payments”). The Restricted Payments cannot exceed the sum of $208.5 million plus (or minus if negative) (a) one-half of the aggregate consolidated net income for the period beginning on April 1, 2014 and ending on the date of determination and (b) the amount of net cash proceeds received from the sale of capital stock after June 2, 2014 and ending on the date of determination less (c) cash dividends and share repurchases after June 2, 2014 (“Credit Facility Restricted Payment Basket”). For purposes of the calculation of the Credit Facility Restricted Payment Basket, net income represents such amounts per the Consolidated Financial Statements adjusted to exclude the Company’s foreign operations, non-cash interest expense, non-cash asset impairment charges, and non-cash stock-based compensation. As of September 30, 2017 , the Credit Facility Restricted Payment Basket totaled $134.4 million . The Company was in compliance with all applicable covenants and ratios under the Revolving Credit Facility as of September 30, 2017 . Ford Motor Credit Company Facility The FMCC Facility provides for the financing of, and is collateralized by, the Company’s Ford new vehicle inventory in the U.S., including affiliated brands. This arrangement provides for $300.0 million of floorplan financing and is an evergreen arrangement that may be canceled with 30 days ' notice by either party. As of September 30, 2017 , the Company had an outstanding balance of $131.7 million under the FMCC Facility with an available floorplan borrowing capacity of $168.3 million . Included in the $168.3 million available borrowings under the FMCC Facility was $22.0 million of immediately available funds. This facility bears interest at a rate of Prime plus 150 basis points minus certain incentives. The interest rate on the FMCC Facility was 5.75% before considering the applicable incentives as of September 30, 2017 . Other Credit Facilities The Company has credit facilities with BMWFS, Volkswagen Finance, Toyota Motor Credit Corporation, FMCC and a third-party financial institution for the financing of new, used and rental vehicle inventories related to its U.K. operations. These facilities are denominated in British pound sterling and are evergreen arrangements that may be canceled with notice by either party and bear interest at a base rate, plus a surcharge that varies based upon the type of vehicle being financed. As of September 30, 2017 , borrowings outstanding under these facilities totaled $123.1 million , with annual interest rates charged on borrowings outstanding under these facilities, after the grace period of zero to 30 days, ranging from 1.25% to 3.95% . The Company has credit facilities with financial institutions in Brazil, most of which are affiliated with the manufacturers, for the financing of new, used and rental vehicle inventories related to its Brazilian operations. These facilities are denominated in Brazilian real and have renewal terms ranging from one month to twelve months. They may be canceled with notice by either party and bear interest at a benchmark rate, plus a surcharge that varies based upon the type of vehicle being financed. As of September 30, 2017 , borrowings outstanding under these facilities totaled $22.5 million , with annual interest rates charged on borrowings outstanding under these facilities, after the grace period of zero to 90 days, ranging from 12.67% to 18.86% . Excluding rental vehicles financed through the Revolving Credit Facility, financing for U.S. rental vehicles is typically obtained directly from the automobile manufacturers. These financing arrangements generally require small monthly payments and mature in varying amounts over a period of two years. Rental vehicles are typically transferred to used vehicle inventory when they are removed from service and repayment of the borrowing is required at that time. As of September 30, 2017 , borrowings outstanding under these rental vehicle facilities totaled $114.3 million , with interest rates that vary up to 5.75% .

Real Estate Related and Other Long-Term Debt The Company, as well as certain of its wholly-owned subsidiaries, has entered into separate term mortgage loans in the U.S. with three of its manufacturer-affiliated finance partners, Toyota Motor Credit Corporation, BMWFS and FMCC, as well as several third-party financial institutions. These mortgage loans may be expanded for borrowings related to specific buildings and/or properties and are guaranteed by the Company. Each mortgage loan was made in connection with, and is secured by mortgage liens on, the real property owned by the Company that is mortgaged under the loans. The mortgage loans bear interest at fixed rates between 3.00% and 4.69% , and at variable indexed rates plus a spread between 1.50% and 2.50% per annum. The mortgage loans consist of 56 term loans for an aggregate principal amount of $371.8 million . As of September 30, 2017 , borrowings outstanding under these mortgage loans totaled $318.5 million , with $29.4 million classified as a current maturity of long-term debt. For the nine months ended September 30, 2017 , the Company made additional net borrowings and principal payments of $10.2 million and $13.7 million , respectively. These mortgage loans are presented net of unamortized underwriters' fees, discount and debt issuance costs, which are being amortized over the terms of the mortgage loans, of $0.6 million as of September 30, 2017 . The agreements provide for monthly payments based on 15 or 20 -year amortization schedules and mature between November 2017 and December 2024 . These mortgage loans are cross-collateralized and cross-defaulted with the mortgages of each respective financial institution. The Company has entered into 16 separate term mortgage loans in the U.K. with other third-party financial institutions which are secured by the Company’s U.K. properties. These mortgage loans (collectively, “U.K. Notes”) are denominated in British pound sterling and are being repaid in monthly installments that will mature by September 2034 . As of September 30, 2017 , borrowings under the U.K. Notes totaled $80.4 million , with $7.4 million classified as a current maturity of long-term debt in the accompanying Consolidated Balance Sheets. For the nine months ended September 30, 2017 , the Company made additional borrowings and principal payments of $28.9 million and $3.9 million , respectively, associated with the U.K. Notes. In addition to the real estate related and other long-term debt, the Company also has two short-term revolving working capital loan agreements and an unsecured loan agreement with third-party financial institutions in the U.K. and U.S., respectively. As of September 30, 2017 , short-term borrowings under the U.K. and U.S. third-party loans totaled $13.2 million and $ 25.1 million , respectively, and are included in current maturities of long-term debt and short-term financing in the Company's Consolidated Balance Sheets. For the nine months ended September 30, 2017 , the Company made additional borrowings of $5.1 million and $25.1 million under the U.K. and U.S. third-party loans, respectively, and no principal payments. The Company has a separate term mortgage loan in Brazil with a third-party financial institution (the "Brazil Note"). The Brazil Note is denominated in Brazilian real and is secured by one of the Company’s Brazilian properties, as well as a guarantee from the Company. The Brazil Note is being repaid in monthly installments that will mature by April 2025 . As of September 30, 2017 , borrowings under the Brazil Note totaled $3.6 million , with $0.3 million classified as a current maturity of long-term debt in the accompanying Consolidated Balance Sheets. For the nine months ended September 30, 2017 , the Company made no additional borrowings and made principal payments of $0.4 million associated with the Brazil Note. The Company also has a working capital loan agreement with a third-party financial institution in Brazil. The principal balance on this loan is due by February 2020 with interest only payments being made quarterly until the due date. As of September 30, 2017 , borrowings outstanding under the Brazilian third-party loan totaled $7.0 million , which are classified as long-term debt in the accompanying Consolidated Balance Sheets. For the nine months ended September 30, 2017 , the Company made no additional borrowings or principal payments. Fair Value of Long-Term Debt The Company's outstanding 5.00% Notes had a fair value of $570.5 million and $548.4 million as of September 30, 2017 and December 31, 2016 , respectively. The Company's outstanding 5.25% Notes had a fair value of $304.4 million and $297.0 million as of September 30, 2017 and December 31, 2016 , respectively. The Company's fixed interest rate borrowings included in real estate related and other long-term debt totaled $88.4 million and $93.9 million as of September 30, 2017 and December 31, 2016 , respectively. The fair value of such fixed interest rate borrowings was $88.6 million and $94.5 million as of September 30, 2017 and December 31, 2016 , respectively. The fair value estimates are based on Level 2 inputs of the fair value hierarchy available as of September 30, 2017 and December 31, 2016 . The Company determined the estimated fair value of its long-term debt using available market information and commonly accepted valuation methodologies. Considerable judgment is required in interpreting market data to develop the estimates of fair value. Accordingly, these estimates are not necessarily indicative of the amounts that the Company, or holders of the instruments, could realize in a current market exchange. The use of different assumptions and/or estimation methodologies could have a material effect on estimated fair values. The carrying value of the Company’s variable rate debt approximates fair value due to the short-term nature of the interest rates.

Fair Value Measurements

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS ASC 820 defines fair value as the price that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date; requires disclosure of the extent to which fair value is used to measure financial and non-financial assets and liabilities, the inputs utilized in calculating valuation measurements, and the effect of the measurement of significant unobservable inputs on earnings, or changes in net assets, as of the measurement date; and establishes a three-level valuation hierarchy based upon the transparency of inputs utilized in the measurement and valuation of financial assets or liabilities as of the measurement date: • Level 1 — unadjusted, quoted prices for identical assets or liabilities in active markets; • Level 2 — quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs other than quoted market prices that are observable or that can be corroborated by observable market data by correlation; and • Level 3 — unobservable inputs based upon the reporting entity’s internally developed assumptions that market participants would use in pricing the asset or liability. The Company’s financial instruments consist primarily of cash and cash equivalents, contracts-in-transit and vehicle receivables, accounts and notes receivable, investments in debt and equity securities, accounts payable, credit facilities, long-term debt and interest rate derivative instruments. The fair values of cash and cash equivalents, contracts-in-transit and vehicle receivables, accounts and notes receivable, accounts payable, and credit facilities approximate their carrying values due to the short-term nature of these instruments and/or the existence of variable interest rates. The Company evaluated its assets and liabilities for those that met the criteria of the disclosure requirements and fair value framework of ASC 820 and identified demand obligations, interest rate derivative instruments, and investment balances in certain financial institutions as having met such criteria. The Company periodically invests in unsecured, corporate demand obligations with manufacturer-affiliated finance companies, which bear interest at a variable rate and are redeemable on demand by the Company. Therefore, the Company has classified these demand obligations as cash and cash equivalents in the accompanying Consolidated Balance Sheets. The Company determined that the valuation measurement inputs of these instruments include inputs other than quoted market prices, that are observable or that can be corroborated by observable data by correlation. Accordingly, the Company has classified these instruments within Level 2 of the hierarchy framework. In addition, the Company maintains an investment balance with certain of the financial institutions in Brazil that provide credit facilities for the financing of new, used and rental vehicle inventories. The investment balances bear interest at a variable rate and are redeemable by the Company in the future under certain conditions. The Company has classified these investment balances as long-term assets in the accompanying Consolidated Balance Sheets. The Company determined that the valuation measurement inputs of these instruments include inputs other than quoted market prices, that are observable or that can be corroborated by observable data by correlation. Accordingly, the Company has classified these instruments within Level 2 of the hierarchy framework. The Company's derivative financial instruments are recorded at fair market value. See Note 3, "Derivative Instruments and Risk Management Activities" for further details regarding the Company's derivative financial instruments. See Note 9, "Long-term Debt" for details regarding the fair value of the Company's long-term debt. Assets and liabilities recorded at fair value, within Level 2 of the hierarchy framework, in the accompanying balance sheets as of September 30, 2017 and December 31, 2016 , respectively, were as follows: As of September 30, 2017 As of December 31, 2016 (In thousands) Assets: Investments $ 708 $ 3,254 Demand obligations 13 12 Interest rate derivative financial instruments 7,701 9,484 Total $ 8,422 $ 12,750 Liabilities: Interest rate derivative financial instruments $ 16,979 $ 24,411 Total $ 16,979 $ 24,411

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES From time to time, the Company’s dealerships are named in various types of litigation involving customer claims, employment matters, class action claims, purported class action claims, as well as claims involving the manufacturer of automobiles, contractual disputes and other matters arising in the ordinary course of business. Due to the nature of the automotive retailing business, the Company may be involved in legal proceedings or suffer losses that could have a material adverse effect on the Company’s business. In the normal course of business, the Company is required to respond to customer, employee and other third-party complaints. Amounts that have been accrued or paid related to the settlement of litigation are included in selling, general and administrative expenses in the Company’s Consolidated Statements of Operations. In addition, the manufacturers of the vehicles that the Company sells and services have audit rights allowing them to review the validity of amounts claimed for incentive, rebate or warranty-related items and charge the Company back for amounts determined to be invalid payments under the manufacturers’ programs, subject to the Company’s right to appeal any such decision. Amounts that have been accrued or paid related to the settlement of manufacturer chargebacks of recognized incentives and rebates are included in cost of sales in the Company’s Consolidated Statements of Operations, while such amounts for manufacturer chargebacks of recognized warranty-related items are included as a reduction of Revenues in the Company’s Consolidated Statements of Operations. Legal Proceedings In late June 2016, Volkswagen agreed to pay up to an aggregate of $14.7 billion to settle claims stemming from the diesel emissions scandal, including claims from customers and automotive dealers. In October 2016 , the Company received notification from Volkswagen that it is entitled to receive, in the aggregate, approximately $13.2 million in connection with the Company's current and prior ownership of seven Volkswagen dealerships in the U.S. The Company accepted and executed the offer in the fourth quarter of 2016 and received half of the compensation in a lump sum amount in January 2017 with the remaining amount to be paid over 18 months. The Company has received eight of the remaining 18 monthly installments as of September 30, 2017 . The Company recognized the entire settlement as an offset to Selling, General and Administrative Expenses ("SG&A") in the Consolidated Statements of Operations for the year ended December 31, 2016 . Also, in conjunction with the Volkswagen diesel emissions scandal, Volkswagen agreed in March 2017 to settle allegations of damages by the Company relative to its three Audi branded dealerships. The Company received the cash and recognized the settlement as an offset to SG&A in the accompanying Consolidated Statements of Operations for the nine months ended September 30, 2017 . Currently, the Company is not party to any legal proceedings that, individually or in the aggregate, are reasonably expected to have a material adverse effect on the Company's results of operations, financial condition, or cash flows, including class action lawsuits. However, the results of current, or future, matters cannot be predicted with certainty, and an unfavorable resolution of one or more of such matters could have a material adverse effect on the Company's results of operations, financial condition, or cash flows. Other Matters The Company, acting through its subsidiaries, is the lessee under many real estate leases that provide for the use by the Company’s subsidiaries of their respective dealership premises. Pursuant to these leases, the Company’s subsidiaries generally agree to indemnify the lessor and other parties from certain liabilities arising as a result of the use of the leased premises, including environmental liabilities, or a breach of the lease by the lessee. Additionally, from time to time, the Company enters into agreements in connection with the sale of assets or businesses in which it agrees to indemnify the purchaser, or other parties, from certain liabilities or costs arising in connection with the assets or business. Also, in the ordinary course of business in connection with purchases or sales of goods and services, the Company enters into agreements that may contain indemnification provisions. In the event that an indemnification claim is asserted, liability would be limited by the terms of the applicable agreement. From time to time, primarily in connection with dealership dispositions, the Company’s subsidiaries sublet to the dealership purchaser the subsidiaries’ interests in any real property leases associated with such dealerships and continue to be primarily obligated on the lease. In these situations, the Company’s subsidiaries retain primary responsibility for the performance of certain obligations under such leases. To the extent that the Company remains primarily responsible under such leases, a quantification of such lease obligations is included in the Company's disclosure of future minimum lease payments for non-cancelable operating leases in Note 18, "Operating Leases" to "Item 8. Financial Statements and Supplementary Data" of the 2016 Form 10-K. In certain instances, also in connection with dealership dispositions, the Company’s subsidiaries assign to the dealership purchaser the subsidiaries’ interests in any real property leases associated with such dealerships. The Company’s subsidiaries may retain secondary responsibility for the performance of certain obligations under such leases to the extent that the assignee does not perform, if such performance is required following the assignment of the lease. Additionally, the Company and its subsidiaries may remain subject to the terms of a guaranty made by the Company and its subsidiaries in connection with such leases. In these circumstances, the Company generally has indemnification rights against the assignee in the event of non-performance under these leases, as well as certain defenses. The Company and its subsidiaries also may be called on to perform other obligations under these leases, such as environmental remediation of the leased premises or repair of the leased premises upon termination of the lease. However, potential environmental liabilities are generally known at the time of the sale of the dealership if not previously remediated. The Company does not have any known material environmental commitments or contingencies and presently has no reason to believe that it or its subsidiaries will be called on to so perform. Although not estimated to be material, the Company’s exposure under these leases is difficult to estimate and there can be no assurance that any performance of the Company or its subsidiaries required under these leases would not have a material adverse effect on the Company’s business, financial condition, or cash flows.

The Company evaluates intangible franchise rights and goodwill assets for impairment annually or more frequently if events or circumstances indicate possible impairment. During the three months ended September 30, 2017 , the Company identified circumstances indicating possible impairment of some individual franchise rights, requiring a quantitative assessment. The Company did not identify any such circumstances relative to the goodwill for each of its reporting units. Based on the results of the Company's assessment, the Company determined that the fair value of the franchise rights on one of its U.S. dealerships was below its respective carrying value, resulting in franchise asset impairment charges of $9.5 million . This was recognized as an asset impairment in the Company's Consolidated Statements of Operations during the three months ended September 30, 2017 .

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION As of September 30, 2017 , the Company had three reportable segments: (1) the U.S., (2) the U.K., and (3) Brazil.

The Company adopted ASU 2015-11 during the first quarter of 2017. The adoption of this ASU did not materially impact its consolidated financial statements or results of operations. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amendment addresses several aspects of the accounting for share-based payment award transactions, including: income tax consequences; classification of awards as either equity or liabilities; and classification on the statement of cash flows. The Company adopted ASU 2016-09 during the first quarter of 2017. The adoption of this ASU did not materially impact its consolidated financial statements or results of operations. Recently Issued Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) that amends the accounting guidance on revenue recognition. The amendments in this ASU are intended to provide a framework for addressing revenue issues, improve comparability of revenue recognition practices, and improve disclosure requirements. This ASU sets forth a five-step model for determining when and how revenue is recognized. Under the model, an entity will be required to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. The amendments in this accounting standard update are effective for interim and annual reporting periods beginning after December 15, 2017. The standard can be adopted either retrospectively to each reporting period presented or as a cumulative effect adjustment as of the date of adoption. To assess the impact of the ASU, the Company established an internal implementation team to review its current accounting policies and practices, identify all material revenue streams, assess the impact of the ASU on its material revenue streams and identify potential differences with current policies and practices. The team has identified the Company’s material revenue streams to be the sale of new and used vehicles; arrangement of associated vehicle financing; the sale of service and insurance contracts; the performance of vehicle maintenance and repair services; and the sale of vehicle parts. The team has reviewed a sample of contracts and other related documents associated with each revenue stream. The team does not anticipate any changes to the timing of revenue recognition for the sale of new and used vehicles. The team is currently evaluating the constraint factors for a portion of the transaction price for certain service and insurance contracts. The new standard requires that an estimate of variable consideration, subject to a constraint, be included in the transaction price and recognized when or as the performance obligation is satisfied. In the event variable consideration is considered fully constrained, recognition will occur once the uncertainties associated with the constraint are determined to be resolved. However, in the event the team's evaluation determines the variable consideration is not fully constrained, revenue would be subject to accelerated recognition under the new standard. As it relates to vehicle maintenance and repair services, the Company currently recognizes revenue once the repair service is completed. The team is currently assessing whether revenue will be recognized over time as the services are performed, under the new standard. The Company’s implementation team is in the final stages of evaluating the additional disclosure requirements of the ASU, as well as the change, if any, to the Company’s underlying accounting and financial reporting systems and processes necessary to support the recognition and disclosure requirements. The Company expects to identify and implement the necessary changes, if any, during the fourth quarter of 2017. At this time, based on this review, the Company does not expect the adoption to materially impact its consolidated financial statements. The Company will adopt the amendments of this ASU during the first fiscal quarter of 2018, using the modified retrospective approach with a cumulative effect adjustment as of the date of adoption. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The amendments in this ASU relate to the accounting for leasing transactions. This standard requires a lessee to record on the balance sheet the assets and liabilities for the rights and obligations created by leases with lease terms of more than 12 months. In addition, this standard requires both lessees and lessors to disclose certain key information about lease transactions. This standard will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is in the process of evaluating the impact that adoption will have on its consolidated balance sheet and statement of income. However, the Company expects that the adoption of the provisions of the ASU will have a significant impact on its consolidated balance sheet, as currently approximately half of its real estate is rented, not owned, via operating leases. Adoption of this ASU is required to be done using a modified retrospective approach. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments . The amendment replaces the current incurred loss impairment methodology of recognizing credit losses when a loss is probable, with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to assess credit loss estimates. The standard will be effective for fiscal years beginning after December 15, 2019, with early adoption permitted for periods after December 15, 2018. The Company is currently evaluating the impact that the adoption of the provisions of the ASU will have on its consolidated financial statements or results of operations, but does not expect the amendments in this ASU to materially impact its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The amendment addresses several specific cash flow issues with the objective of reducing the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The standard will be effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of the provisions of the ASU will have on its consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, a consensus of the FASB Emerging Issues Task Force ("EITF") . The amendments require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this ASU do not provide a definition of restricted cash or restricted cash equivalents. The standard will be effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of the provisions of the ASU will have on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business . The amendments in this update clarify the definition of a business in order to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in this ASU should be applied prospectively and are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact on its consolidated financial statements as it will depend on the facts and circumstances of any specific future transactions. In January 2017, the FASB issued ASU 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments-Equity Method and Joint Ventures (Topic 323): Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 17, 2016 EITF Meetings . The amendments in this update require the disclosure of the impact that a recently issued ASU will have on the financial statements of a registrant when such standards are to be adopted in a future period. The SEC staff views that a registrant should evaluate ASU's that have not yet been adopted to determine the appropriate financial statement disclosures about the potential material effects of those ASU's on the financial statements when adopted. The Company does not expect the amendments in this ASU to materially impact its consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . The amendment eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit's carrying amount over its fair value. The amendments in this update should be applied prospectively and are effective for interim and annual periods beginning after December 15, 2019. Earlier application is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact that the adoption of the provisions of the ASU will have on its consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting . The amendments in this update provide clarity and reduce both diversity in practice and cost and complexity when applying the guidance of Topic 718 to a change to the terms or conditions of a share-based payment award. Under the new guidance, an entity will not apply modification accounting to a share-based payment award if all of the following are the same immediately before and after the change: 1) the award's fair value (or calculated value or intrinsic value, if those measurement methods are used), 2) the award's vesting conditions, and 3) the award's classification as an equity or liability instrument. The amendments in this ASU should be applied prospectively and are effective for fiscal years beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the impact on its consolidated financial statements as it will depend on the facts and circumstances of any specific future transactions. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 715): Targeted Improvements to Accounting for Hedging Activities. The amendments in this update better align an entity's risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The guidance also eases the administrative burden of hedge documentation requirements and assessing hedge effectiveness. The amendments to cash flow and net investment hedge relationships should be applied using a modified retrospective approach while the presentation and disclosure requirements are applied prospectively, effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact that the adoption of the provisions of the ASU will have on its consolidated financial statements.
Basis of Presentation [Text Block]	Basis of Presentation The accompanying unaudited condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the U.S. ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments of a normal and recurring nature considered necessary for a fair presentation have been included in the accompanying unaudited condensed Consolidated Financial Statements. Due to seasonality and other factors, the results of operations for the interim period are not necessarily indicative of the results that will be realized for any other interim period or for the entire fiscal year. For further information, refer to the Consolidated Financial Statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 (“ 2016 Form 10-K”). All business acquisitions completed during the periods presented have been accounted for using the purchase method of accounting, and their results of operations are included from the effective dates of the closings of the acquisitions. The allocations of purchase price to the assets acquired and liabilities assumed are assigned and recorded based on estimates of fair value and are subject to change within the purchase price allocation period (generally one year from the respective acquisition date). All intercompany balances and transactions have been eliminated in consolidation.
Segment Reporting Disclosure [Text Block]	Business Segment Information The Company has three reportable segments: the U.S., which includes the activities of the Company's corporate office, the U.K. and Brazil. The reportable segments are the business activities of the Company for which discrete financial information is available and for which operating results are regularly reviewed by its chief operating decision maker to allocate resources and assess performance. The Company's chief operating decision maker is its Chief Executive Officer.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives, Policy [Policy Text Block]	The periodic interest rates of the Revolving Credit Facility (as defined in Note 8, “Credit Facilities”) and certain variable-rate real estate related borrowings in the U.S. are indexed to the one-month London Inter Bank Offered Rate (“LIBOR”), plus an associated company credit risk rate. In order to minimize the earnings variability related to fluctuations in these periodic interest rates, the Company employs an interest rate hedging strategy, whereby it enters into arrangements with various financial institutional counterparties with investment grade credit ratings, swapping its variable interest rate exposure for a fixed interest rate over terms not to exceed the related variable-rate debt. The Company presents the fair value of all interest rate derivative instruments on its Consolidated Balance Sheets. The Company measures the fair value of its interest rate derivative instruments utilizing an income approach valuation technique, converting future amounts of cash flows to a single present value in order to obtain a transfer exit price within the bid and ask spread that is most representative of the fair value of its derivative instruments. In measuring fair value, the Company utilizes the option-pricing Black-Scholes present value technique for all of its derivative instruments. This option-pricing technique utilizes a one-month LIBOR forward yield curve, obtained from an independent external service provider, matched to the identical maturity term of the instrument being measured. Observable inputs utilized in the income approach valuation technique incorporate identical contractual notional amounts, fixed coupon rates, periodic terms for interest payments and contract maturity. The fair value estimate of the interest rate derivative instruments also considers the credit risk of the Company for instruments in a liability position or the counterparty for instruments in an asset position. The credit risk is calculated by using the spread between the one-month LIBOR yield curve and the relevant average 10 and 20-year rate according to Standard and Poor’s. The Company has determined the valuation measurement inputs of these derivative instruments to maximize the use of observable inputs that market participants would use in pricing similar or identical instruments and market data obtained from independent sources, which is readily observable or can be corroborated by observable market data for substantially the full term of the derivative instrument. Further, the valuation measurement inputs minimize the use of unobservable inputs. Accordingly, the Company has classified the derivatives within Level 2 of the hierarchy framework as described by Accounting Standards Codification ("ASC") 820, Fair Value Measurement . The related gains or losses on these interest rate derivative instruments are deferred in stockholders’ equity as a component of accumulated other comprehensive loss. These deferred gains and losses are recognized in income in the period in which the related items being hedged are recognized in expense. However, to the extent that the change in value of a derivative contract does not perfectly offset the change in the value of the items being hedged, that ineffective portion is immediately recognized in other income or expense. Monthly contractual settlements of these swap positions are recognized as floorplan or other interest expense in the Company’s accompanying Consolidated Statements of Operations. All of the Company’s interest rate derivative instruments are designated as cash flow hedges.

Fair Value Disclosures [Abstract]
Fair Value of Assets Acquired and Liabilities Assumed [Policy Text Block]	ASC 820 defines fair value as the price that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date; requires disclosure of the extent to which fair value is used to measure financial and non-financial assets and liabilities, the inputs utilized in calculating valuation measurements, and the effect of the measurement of significant unobservable inputs on earnings, or changes in net assets, as of the measurement date; and establishes a three-level valuation hierarchy based upon the transparency of inputs utilized in the measurement and valuation of financial assets or liabilities as of the measurement date: • Level 1 — unadjusted, quoted prices for identical assets or liabilities in active markets; • Level 2 — quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs other than quoted market prices that are observable or that can be corroborated by observable market data by correlation; and • Level 3 — unobservable inputs based upon the reporting entity’s internally developed assumptions that market participants would use in pricing the asset or liability. The Company’s financial instruments consist primarily of cash and cash equivalents, contracts-in-transit and vehicle receivables, accounts and notes receivable, investments in debt and equity securities, accounts payable, credit facilities, long-term debt and interest rate derivative instruments. The fair values of cash and cash equivalents, contracts-in-transit and vehicle receivables, accounts and notes receivable, accounts payable, and credit facilities approximate their carrying values due to the short-term nature of these instruments and/or the existence of variable interest rates. The Company evaluated its assets and liabilities for those that met the criteria of the disclosure requirements and fair value framework of ASC 820 and identified demand obligations, interest rate derivative instruments, and investment balances in certain financial institutions as having met such criteria. The Company periodically invests in unsecured, corporate demand obligations with manufacturer-affiliated finance companies, which bear interest at a variable rate and are redeemable on demand by the Company. Therefore, the Company has classified these demand obligations as cash and cash equivalents in the accompanying Consolidated Balance Sheets. The Company determined that the valuation measurement inputs of these instruments include inputs other than quoted market prices, that are observable or that can be corroborated by observable data by correlation. Accordingly, the Company has classified these instruments within Level 2 of the hierarchy framework. In addition, the Company maintains an investment balance with certain of the financial institutions in Brazil that provide credit facilities for the financing of new, used and rental vehicle inventories. The investment balances bear interest at a variable rate and are redeemable by the Company in the future under certain conditions. The Company has classified these investment balances as long-term assets in the accompanying Consolidated Balance Sheets. The Company determined that the valuation measurement inputs of these instruments include inputs other than quoted market prices, that are observable or that can be corroborated by observable data by correlation. Accordingly, the Company has classified these instruments within Level 2 of the hierarchy framework. The Company's derivative financial instruments are recorded at fair market value.

The Company did not identify any such circumstances relative to the goodwill for each of its reporting units. Based on the results of the Company's assessment, the Company determined that the fair value of the franchise rights on one of its U.S. dealerships was below its respective carrying value, resulting in franchise asset impairment charges of $9.5 million . This was recognized as an asset impairment in the Company's Consolidated Statements of Operations during the three months ended September 30, 2017 .

Segment Reporting Information [Line Items]
Income Tax Disclosure [Text Block]			INCOME TAXES The Company is subject to U.S. federal income taxes and income taxes in numerous U.S. states. In addition, the Company is subject to income tax in the U.K. and Brazil relative to its foreign subsidiaries. The Company's effective income tax rate of 36.6% for the three months ended September 30, 2017 was more than the U.S. federal statutory rate of 35.0% , due primarily to the taxes provided for in U.S. state jurisdictions, valuation allowances provided for net operating losses and other deferred tax assets in certain U.S. states and in Brazil and unrecognized tax benefits with respect to uncertain tax positions, partially offset by income generated in the U.K., which is taxed at a lower statutory rate. The Company's effective income tax rate of 35.7% of pretax income for the nine months ended September 30, 2017 , was more than the U.S. federal statutory rate of 35.0% , as taxes provided for in the U.S. state jurisdictions and valuation allowances provided for net operating losses and other deferred tax assets in certain U.S. states and in Brazil and unrecognized tax benefits with respect to uncertain tax positions, were substantially offset by (a) income generated in the U.K., which is taxed at a lower statutory rate, (b) the tax impact of dealership dispositions in Brazil, and (c) excess tax deductions for restricted stock resulting from the adoption of ASU 2016-09 during the nine months ended September 30, 2017 . For the three and nine months ended September 30, 2017 , the Company's effective tax rate increased to 36.6% and 35.7% , respectively, as compared to 36.5% and 35.0% for the three and nine months ended September 30, 2016 , respectively. This increase was primarily due to the mix effect resulting from taxes provided for in foreign jurisdictions, changes to valuation allowances provided for net operating losses and other deferred tax assets in certain U.S. states and in Brazil and unrecognized tax benefits with respect to uncertain tax positions during the three and nine months ended September 30, 2017, partially offset by excess tax deductions for restricted stock resulting from the adoption of ASU 2016-09 during the nine months ended September 30, 2017 , as well as the tax impact of dealership dispositions in Brazil during the nine months ended September 30, 2016 . As of September 30, 2017 , the Company recorded $1.2 million unrecognized tax benefits, including $0.2 million of related interest and penalty. As of December 31, 2016 , the Company had no unrecognized tax benefits with respect to uncertain tax positions and did not incur any interest and penalties. Consistent with prior treatment of tax related assessments, the Company recognizes interest and penalties related to uncertain tax positions in income tax expense. The Company's taxable years 2013 and subsequent remain open for examination in the U.S. The Company's taxable years 2015 and subsequent remain open in the U.K. and taxable years 2012 and subsequent remain open in Brazil.

[1]	1) Net of accumulated impairment of $97.8 million.The Company evaluates intangible franchise rights and goodwill assets for impairment annually or more frequently if events or circumstances indicate possible impairment. During the three months ended September 30, 2017, the Company identified circumstances indicating possible impairment of some individual franchise rights, requiring a quantitative assessment. The Company did not identify any such circumstances relative to the goodwill for each of its reporting units. Based on the results of the Company's assessment, the Company determined that the fair value of the franchise rights on one of its U.S. dealerships was below its respective carrying value, resulting in franchise asset impairment charges of $9.5 million. This was recognized as an asset impairment in the Company's Consolidated Statements of Operations during the three months ended September 30, 2017.

[1]	1) Net of accumulated impairment of $97.8 million.The Company evaluates intangible franchise rights and goodwill assets for impairment annually or more frequently if events or circumstances indicate possible impairment. During the three months ended September 30, 2017, the Company identified circumstances indicating possible impairment of some individual franchise rights, requiring a quantitative assessment. The Company did not identify any such circumstances relative to the goodwill for each of its reporting units. Based on the results of the Company's assessment, the Company determined that the fair value of the franchise rights on one of its U.S. dealerships was below its respective carrying value, resulting in franchise asset impairment charges of $9.5 million. This was recognized as an asset impairment in the Company's Consolidated Statements of Operations during the three months ended September 30, 2017.
