	DESCRIPTION OF BUSINESS
	We are one of the largest automotive retailers in the United States, operating 100 franchises (80 dealership locations) in 18 metropolitan markets within 10 states as of December 31, 2013. We offer an extensive range of automotive products and services, including new and used vehicles; vehicle maintenance, replacement parts and collision repair services; and financing, insurance and service contracts. As of December 31, 2013, we offered 29 domestic and foreign brands of new vehicles. Our current brand mix is weighted 86% towards luxury and mid-line import brands, with the remaining 14% consisting of domestic brands. We also operate 24 collision repair centers that serve customers in our local markets.
	Our retail network is made up of dealerships operating primarily under the following locally-branded dealership groups:
	•	Coggin dealerships, operating primarily in Jacksonville, Fort Pierce and Orlando, Florida;
	•	Courtesy dealerships operating in Tampa, Florida;
	•	Crown dealerships operating in New Jersey, North Carolina, South Carolina and Virginia;
	•	Nalley dealerships operating in metropolitan Atlanta, Georgia;
	•	McDavid dealerships operating in Austin, Dallas and Houston, Texas;
	•	North Point dealerships operating in the Little Rock, Arkansas area;
	•	Plaza dealerships operating in metropolitan St. Louis, Missouri; and
	•	Gray-Daniels dealerships operating in the Jackson, Mississippi area.
	Our operating results are generally subject to changes in the economic environment as well as seasonal variations. Historically, we have generated more revenue and operating income in the second and third quarters than in the first and fourth quarters of the calendar year. Generally, the seasonal variations in our operations are caused by factors related to weather conditions, changes in manufacturer incentive programs, model changeovers and consumer buying patterns, among other things.

Summary of Significant Accounting Policies	12 Months Ended

Accounting Policies [Abstract]	'
Summary of Significant Accounting Policies	'
	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation
	The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”), and reflect the consolidated accounts of Asbury Automotive Group, Inc. and our wholly owned subsidiaries. All intercompany transactions have been eliminated in consolidation. In addition, certain reclassifications of amounts previously reported have been made to the accompanying Consolidated Financial Statements in order to conform to current presentation.
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the periods presented. Actual results could differ materially from these estimates. Estimates and assumptions are reviewed quarterly and the effects of any revisions are reflected in the consolidated financial statements in the period they are determined to be necessary. Significant estimates made in the accompanying consolidated financial statements include, but are not limited to, those relating to inventory valuation reserves, reserves for chargebacks against revenue recognized from the sale of finance and insurance products, certain assumptions related to intangible and long-lived assets, reserves for insurance programs, reserves for certain legal or similar proceedings relating to our business operations, realization of deferred tax assets and reserves for estimated tax liabilities.
	Cash and Cash Equivalents
	Cash and cash equivalents include investments in money market accounts and short-term certificates of deposit which have maturity dates of less than 90 days when purchased.
	Contracts-In-Transit
	Contracts-in-transit represent receivables from third-party finance companies for the portion of new and used vehicle purchase price financed by customers through sources arranged by us. Amounts due from contracts-in-transit are generally collected within two weeks following the date of sale of the related vehicle.
	Inventories
	Inventories are stated at the lower of cost or market. We use the specific identification method to value vehicle inventories and the “first-in, first-out” method (“FIFO”) to account for our parts inventories. We maintain a reserve for specific used vehicles where cost basis exceeds market value. Our new vehicle sales histories have indicated that the vast majority of the new vehicles we sell are sold for, or in excess of, our cost to purchase those vehicles. Therefore, we generally do not maintain a reserve for specific new vehicle inventory. In assessing lower of cost or market for used vehicles, we consider (i) the aging of our used vehicles, (ii) historical sales experience of used vehicles and (iii) current market conditions and trends for used vehicles. We also review and consider the following metrics related to used vehicle sales (both on a recent and longer-term historical basis): (a) days of supply in our used vehicle inventory, (b) used vehicle units sold at less than original cost as a percentage of total used vehicles sold and (c) average vehicle selling price of used vehicle units sold at less than original cost. We then determine the appropriate level of reserve required to reduce our used vehicle inventory to the lower of cost or market, and record the resulting adjustment in the period in which we determine a loss has occurred. The level of reserve determined to be appropriate for each reporting period is considered to be a permanent inventory write-down and therefore is only released upon the sale of the related inventory.
	We receive assistance from certain automobile manufacturers in the form of advertising and interest credits. Manufacturer advertising credits that are reimbursements of costs associated with specific advertising programs are recognized as a reduction of advertising expense in the period they are earned. All other manufacturer advertising and interest credits are accounted for as purchase discounts and are recorded as a reduction of inventory and recognized as a reduction to New Vehicle Cost of Sales in the accompanying Consolidated Statements of Income in the period the related vehicle is sold.
	Property and Equipment
	Property and equipment are recorded at cost and depreciated using the straight-line method over their estimated useful lives. Depreciation is included in Depreciation and Amortization and Discontinued Operations, net of tax, on the accompanying Consolidated Statements of Income. Leasehold improvements are capitalized and amortized over the lesser of the life of the lease or the useful life of the related asset. The ranges of estimated useful lives are as follows (in years):
	Buildings and improvements	Oct-40
	Machinery and equipment	10-May
	Furniture and fixtures	10-Mar
	Company vehicles	5-Mar
	Expenditures for major additions or improvements, which extend the useful lives of assets, are capitalized. Minor replacements, maintenance and repairs, which do not improve or extend the lives of such assets, are expensed as incurred.
	We review property and equipment for impairment whenever events or changes in circumstances indicate the carrying value may not be recoverable. When we test our long-lived assets for impairment, we first compare the carrying amount of the underlying assets to their net recoverable value by reviewing the undiscounted cash flows expected to result from the use and eventual disposition of the underlying assets. If the carrying amount of the underlying assets is less than their net recoverable value, then we calculate an impairment equal to the excess of the carrying amount over the fair market value, and the impairment loss would be charged to operations in the period identified. As a result of impairment tests conducted in 2013, 2012 and 2011, we recorded only immaterial impairments of certain of our property and equipment in those periods.
	We capitalize interest on borrowings during the active construction period of capital projects. Capitalized interest is added to the cost of the assets and is depreciated over the estimated useful lives of the assets.
	Acquisitions
	Acquisitions are accounted for under the purchase method of accounting and the assets acquired and liabilities assumed are recorded at their fair value as of the acquisition dates. The operations of acquired dealerships are included in the accompanying Consolidated Statements of Income commencing on the date of acquisition.
	Goodwill and Other Intangible Assets
	Goodwill represents the excess cost of the businesses acquired over the fair market value of the identifiable net assets. We have determined that, based on how we integrate acquisitions into our business, how the components of our business share resources and interact with one another, and the fact that all components are economically similar, we qualify as a single reporting unit for purposes of testing goodwill for impairment.
	Our only significant identifiable intangible assets, other than goodwill, are rights under franchise agreements with manufacturers, which are recorded at an individual dealership level. The fair market value of our manufacturer franchise rights, which are included in Other Long Term Assets on the accompanying Consolidated Balance Sheets, is determined at the acquisition date through discounting the projected cash flows specific to each franchise. We have determined that manufacturer franchise rights have an indefinite life as there are no economic, contractual or other factors that limit their useful lives and they are expected to generate cash flows indefinitely due to the historically long lives of the manufacturers’ brand names. Furthermore, to the extent that any agreements evidencing our manufacturer franchise rights would expire, we expect that we would be able to renew those agreements in the ordinary course of business.
	We do not amortize goodwill and other intangible assets that are deemed to have indefinite lives. We review goodwill and manufacturer franchise rights for impairment annually as of October 1st of each year, or more often if events or circumstances indicate that impairment may have occurred. We are subject to financial statement risk to the extent that manufacturer franchise rights become impaired due to decreases in fair market value of our individual franchises or to the extent that goodwill becomes impaired due to decreases in the fair market value of our automotive retail business.
	We completed our annual intangible impairment tests as of October 1, 2013, and no impairment of goodwill or other intangible assets was recognized as a result of such tests.
	Debt Issuance Costs
	Debt issuance costs are capitalized and included in Other Current Assets and Other Long-Term Assets in the accompanying Consolidated Balance Sheets. Debt issuance costs are amortized to Other Interest Expense, net and Floor Plan Interest Expense in the accompanying Consolidated Statements of Income through maturity using either the effective interest method or straight line method.
	Derivative Instruments and Hedging Activities
	From time to time, we utilize derivative financial instruments to manage our capital structure and interest rate risk. The types of risks hedged are those relating to the variability of cash flows and changes in the fair value of our financial instruments caused by movements in interest rates. We document our risk management strategy and assess hedge effectiveness at the inception and during the term of each hedge. Derivatives are reported at fair value on the accompanying Consolidated Balance Sheets.
	The effective portion of the gain or loss on our cash flow hedges is reported as a component of Accumulated Other Comprehensive Loss on the accompanying Consolidated Balance Sheets and reclassified to Swap Interest Expense in the accompanying Consolidated Statements of Income in the same period during which the hedged transaction affects earnings.
	Measurements of hedge effectiveness are based on comparisons between the gains or losses of the actual interest rate swaps and the gains or losses of hypothetical interest rate swaps, which have the same critical terms of the defined hedged items. Ineffective portions of these interest rate swaps are reported as a component of interest expense in the accompanying Consolidated Statements of Income.
	Insurance
	We are self insured for employee medical claims and maintain stop loss insurance for large-dollar individual claims. We have large deductible insurance programs for workers compensation, property and general liability claims. We maintain and review our claim and loss history to assist in assessing our expected future liability for these claims. We also use professional service providers, such as account administrators and actuaries, to help us accumulate and assess this information.
	Revenue Recognition
	Revenue from the sale of new and used vehicles (which excludes sales tax) is recognized upon the latest of delivery, passage of title, signing of the sales contract or approval of financing. Revenue from the sale of parts, service and collision repair work (which excludes sales tax) is recognized upon delivery of parts to the customer or at the time vehicle service or repair work is completed, as applicable. Manufacturer incentives and rebates, including manufacturer holdbacks, floor plan interest assistance and certain advertising assistance, are recognized as a reduction of new vehicle cost of sales at the time the related vehicles are sold.
	We receive commissions from third-party lending and insurance institutions for arranging customer financing and from the sale of vehicle service contracts, credit life insurance and disability insurance, and other insurance, to customers (collectively “F&I”). We may be charged back (“chargebacks”) for F&I commissions in the event a contract is prepaid, defaulted upon or terminated. F&I commissions are recorded at the time a vehicle is sold and a reserve for future chargebacks is established based on historical chargeback experience and the termination provisions of the applicable contract. F&I commissions, net of estimated future chargebacks, are included in Finance and Insurance, net in the accompanying Consolidated Statements of Income.
	Internal Profit
	Revenues and expenses associated with the internal work performed by our parts and service departments on new and used vehicle inventory are eliminated in consolidation. The gross profit earned by our parts and service departments for internal work performed is included as a reduction of Parts and Service Cost of Sales on the accompanying Consolidated Statements of Income. The costs incurred by our new and used vehicle departments for work performed by our parts and service departments is included in either New Vehicle Cost of Sales or Used Vehicle Cost of Sales on the accompanying Consolidated Statements of Income, depending on the classification of the vehicle serviced. We maintain a reserve to eliminate the internal profit on vehicles that have not been sold.
	Share-Based Compensation
	We record share-based compensation expense under the fair value method on a straight-line basis over the vesting period, unless the awards are subject to performance conditions, in which case we recognize the expense over the requisite service period of each separate vesting tranche.
	Earnings per Common Share
	Basic earnings per common share is computed by dividing net income by the weighted-average common shares outstanding during the period. Diluted earnings per common share is computed by dividing net income by the weighted-average common shares and common share equivalents outstanding during the period. For all periods presented, there were no adjustments to the numerator necessary to compute diluted earnings per share.
	Advertising
	We expense costs of advertising as incurred and production costs when the advertising initially takes place, net of certain advertising credits and other discounts. Advertising expense from continuing operations totaled $32.8 million, $27.8 million and $25.3 million for the years ended December 31, 2013, 2012 and 2011, net of earned advertising credits and volume discounts of $13.5 million, $11.8 million and $9.5 million, respectively, and is included in Selling, General and Administrative expense in the accompanying Consolidated Statements of Income.
	Income Taxes
	We use the liability method to account for income taxes. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax basis using currently enacted tax rates. The effect on deferred assets and liabilities of a change in tax rates is recognized in income in the period when the change is enacted. Deferred tax assets are reduced by a valuation allowance when it is more likely than not that some portion or all the deferred tax assets will not be realized.
	Discontinued Operations
	Certain amounts reflected in the accompanying Consolidated Balance Sheets have been classified as Assets Held for Sale or Liabilities Associated with Assets Held for Sale, with such classification beginning on the date that the assets and associated liabilities were first considered held for sale.
	We report franchises and ancillary businesses as discontinued operations when it is evident that the operations and cash flows of a franchise or ancillary business being actively marketed for sale will be eliminated from our on-going operations and that we will not have any significant continuing involvement in its operations. We do not classify franchises as discontinued operations if we believe that the cash flows generated by the franchise will be replaced by expanded operations of our remaining franchises within the respective local market area.
	Amounts in the accompanying Consolidated Statements of Income for the years ended December 31, 2012 and December 31, 2011 have been reclassified to reflect the results of franchises sold or closed during 2013 as if we had classified those franchises as discontinued operations for all years presented.
	Statements of Cash Flows
	Borrowings and repayments of floor plan notes payable to a lender unaffiliated with the manufacturer from which we purchase a particular new vehicle ("Non-Trade"), and all floor plan notes payable relating to pre-owned vehicles (together referred to as "Floor Plan Notes Payable-Non-Trade"), are classified as financing activities on the accompanying Consolidated Statements of Cash Flows, with borrowings reflected separately from repayments. The net change in floor plan notes payable to a lender affiliated with the manufacturer from which we purchase a particular new vehicle (collectively referred to as “Floor Plan Notes Payable - Trade”) is classified as an operating activity on the accompanying Consolidated Statements of Cash Flows. Borrowings of floor plan notes payable associated with inventory acquired in connection with all acquisitions are classified as a financing activity. Cash flows related to floor plan notes payable included in operating activities differ from cash flows related to floor plan notes payable included in financing activities only to the extent that the former are payable to a lender affiliated with the manufacturer from which we purchased the related inventory, while the latter are payable to a lender not affiliated with the manufacturer from which we purchased the related inventory. Repayments of Floor Plan Notes Payable - Trade associated with divestitures are classified as an operating activity. Repayments of Floor Plan Notes Payable - Non-Trade associated with divestitures are classified as a financing activity.
	Loaner vehicles account for a significant portion of Other Current Assets. We acquire loaner vehicles either with available cash or through borrowings from manufacturer affiliated lenders. Loaner vehicles are initially used by our service department for only a short period of time (typically six to twelve months) before we seek to sell them. Therefore, we classify the acquisition of loaner vehicles and the related borrowings and repayments as operating activities in the accompanying Consolidated Statements of Cash Flows. The cash outflow to acquire loaner vehicles is presented in Other Current Assets in the accompanying Consolidated Statements of Cash Flows. Borrowings and repayments of loaner vehicle notes payable are presented in Accounts Payable and Accrued Liabilities in the accompanying Consolidated Statements of Cash Flows. When loaner vehicles are taken out of loaner status they are transferred to used vehicle inventory, which is reflected as a non-cash transfer in the accompanying Consolidated Statements of Cash Flows. The cash inflow from the sale of loaner vehicles is reflected in Inventories in the accompanying Consolidated Statements of Cash Flows.
	Business and Credit Concentration Risk
	Financial instruments, which potentially subject us to concentration of credit risk, consist principally of cash deposits. We maintain cash balances at financial institutions with strong credit ratings. Generally, amounts invested with financial institutions are in excess of FDIC insurance limits.
	We have substantial debt service obligations. As of December 31, 2013, we had total debt of $554.4 million, excluding floor plan notes payable on our accompanying Consolidated Balance Sheet. In addition, we and our subsidiaries have the ability to obtain additional debt from time to time to finance acquisitions, real property purchases, capital expenditures or for other purposes, although such borrowings are subject to the restrictions contained in the credit agreement governing our senior secured credit facilities and the indenture governing our 8.375% Senior Subordinated Notes due 2020 (the "8.375% Notes"). We will have substantial debt service obligations, consisting of required cash payments of principal and interest, for the foreseeable future.
	We are subject to operating and financial restrictions and covenants in certain of our leases and in our debt instruments, including the credit agreement governing our senior secured credit facilities, the 8.375% Notes indenture and the credit agreements covering our mortgage obligations. These agreements contain restrictions on, among other things, our ability to incur additional indebtedness, to create liens or other encumbrances, and to make certain payments (including dividends and repurchases of our shares and investments). These agreements may also require us to maintain compliance with certain financial and other ratios. Our failure to comply with any of these covenants in the future would constitute a default under the relevant agreement, which would, depending on the relevant agreement, (i) entitle the creditors under such agreement to terminate our ability to borrow under the relevant agreement and accelerate our obligations to repay outstanding borrowings; (ii) require us to apply our available cash to repay these borrowings; (iii) entitle the creditors under such agreement to foreclose on the property securing the relevant indebtedness; and/or (iv) prevent us from making debt service payments on certain of our other indebtedness, any of which would have a material adverse effect on our business, financial condition or results of operations. In many cases, a default under one of our debt or mortgage, agreements could trigger cross default provisions in one or more of our other debt or mortgages.
	A number of our dealerships are located on properties that we lease. Each of the leases governing such properties has certain covenants with which we must comply. If we fail to comply with the covenants under our leases, the respective landlords could terminate the leases and seek damages from us.
	Concentrations of credit risk with respect to contracts-in-transit and accounts receivable are limited primarily to automotive manufacturers and financial institutions. Credit risk arising from receivables from commercial customers is minimal due to the large number of customers comprising our customer base.
	A significant portion of our new vehicle sales are derived from a limited number of automotive manufacturers. For the year ended December 31, 2013, brands representing 5% or more of our revenues from new vehicle sales were as follows:
	Brand	% of Total
New
Vehicle Revenues
Honda	20	%
Nissan	13	%
Toyota	11	%
BMW	9	%
Ford	7	%
Mercedes-Benz	7	%
Lexus	7	%
Acura	5	%
No other brand accounted for more than 5% of our total new vehicle revenue for the year ended December 31, 2013.
Segment Reporting
We have determined that as a result of how we internally view our business, regularly review our financial data and operating metrics and allocate resources that we operate in one segment, automotive retail. Our Chief Operating Decision Maker is our Chief Executive Officer who manages the business, regularly reviews financial information and allocates resources on a consolidated basis. Our dealerships are components of our automotive retail segment and, therefore, are not segments themselves.
Recent Accounting Pronouncements
During the first quarter of 2013, we adopted an accounting standard regarding the presentation of comprehensive income. This update was issued to improve the reporting of reclassifications out of Accumulated Other Comprehensive Income ("AOCI"). The update requires that significant items reclassified out of AOCI be presented in one place in the consolidated financial statements. The adoption of this standard update did not have a significant impact on our consolidated financial statements.

	ACQUISITIONS
	Results of acquired dealerships are included in our accompanying Consolidated Statements of Income commencing on the date of acquisition. Our acquisitions are accounted for using the acquisition method of accounting, which requires, among other things, that the assets acquired and liabilities assumed be recognized at their acquisition date fair values, with any excess of the purchase price over the estimated fair values of the identifiable net assets acquired recorded as a combination of goodwill and manufacturer franchise rights.
	In July 2013, we acquired three franchises (three dealership locations) for an aggregate purchase price of $61.8 million. We financed these acquisitions with $50.5 million of cash and $11.3 million of floor plan borrowings for the purchase of the related new vehicle inventory
	In the fourth quarter of 2012, we acquired two franchises (two dealership locations) for an aggregate purchase price of $34.7 million. We financed the acquisitions with $26.9 million of cash and $7.8 million of floor plan borrowings for the purchase of the related new vehicle inventory
	Below is the allocation of purchase price for acquisitions completed during 2013 and 2012. The $29.6 million and $11.6 million of goodwill and manufacturer franchise rights associated with our 2013 and 2012 acquisitions will be deductible for federal and state income taxes ratably over a 15 year period.

The impairment tests indicated an impairment of certain of our property and equipment. Accordingly, we recognized impairment expenses of $2.3 million and $1.1 million during 2012 and 2011, respectively, based on market approaches using Level 2 fair value inputs.

	FLOOR PLAN NOTES PAYABLE
	In August 2013, the Company and certain of its subsidiaries entered into an amended and restated senior secured credit agreement with Bank of America, N.A. (“Bank of America”), as administrative agent, and the other agents and lenders party thereto (the “Restated Credit Agreement”). The Restated Credit Agreement amended and restated in its entirety the Company’s pre-existing senior secured credit agreement, dated as of October 14, 2011, by and among the Company and certain of its subsidiaries and Bank of America, as administrative agent, and the other agents and lenders party thereto (the “Prior Credit Agreement”). The Prior Credit Agreement had provided for our senior secured credit facilities, consisting of (i) a $175.0 million revolving credit facility with a $50.0 million sublimit for letters of credit (discussed further below under our “Long Term Debt” footnote), (ii) a $625.0 million new vehicle revolving floor plan facility, and (iii) a $100.0 million used vehicle revolving floor plan facility, in each case subject to limitations on borrowing availability as set out in the Prior Credit Agreement.
	The terms of the Restated Credit Agreement provide that:
	•	the new vehicle inventory floor plan facility thereunder was increased by $200.0 million to $825.0 million;
	•	the interest rates on borrowings under the new vehicle and used vehicle floor plan facilities thereunder each decreased by 25 basis points to the one-month London Interbank Offered Rate ("LIBOR") plus 1.25% and one-month LIBOR plus 1.50%, respectively, in each case as compared to the terms of the Prior Credit Agreement; and
	•	the maturity date of the Prior Credit Agreement was extended from October 2016 until August 2018.
	Except as described above, the terms of the Restated Credit Agreement did not materially change the terms of the Prior Credit Agreement. Subject to the compliance with certain conditions, the Restated Credit Agreement provides that we and our dealership subsidiaries that are borrowers under the senior secured credit facilities (collectively, the “Borrowers”) have the ability, at their option and subject to the receipt of additional commitments from existing or new lenders, to increase the size of the new vehicle floor plan facility or the used vehicle floor plan facility by up to $250.0 million in the aggregate without lender consent.
	In addition to the payment of interest on borrowings outstanding under the senior secured credit facilities, the Borrowers are required to pay a commitment fee on the total commitments under the senior secured credit facilities. The fees for commitments under the new vehicle revolving floor plan facility and the used vehicle revolving floor plan facility are 0.20% per annum and 0.25% per annum, respectively, and are payable on a quarterly basis.
	We consider floor plan notes payable to a party that is affiliated with the entity from which we purchase our new vehicle inventory “Floor plan notes payable—trade” and all other floor plan notes payable “Floor plan notes payable—non-trade.” The majority of our floor plan notes are payable to parties unaffiliated with the entities from which we purchase our new vehicle inventory, with the exception of floor plan notes payable relating to the financing of new Ford and Lincoln vehicles, and certain loaner vehicles. As of December 31, 2013, we had $74.7 million of floor plan notes payable—trade and $534.8 million of floor plan notes payable—non-trade outstanding.
	As of December 31, 2013 and 2012, we had a total of $609.5 million and $562.1 million of floor plan notes payable outstanding, respectively, including $5.4 million classified as Liabilities Associated with Assets Held for Sale as of December 31, 2012.
	In connection with our vehicle floor plan facility described above, we have established an account with Bank of America that allows us to transfer cash to an account as an offset to floor plan notes payable (a “floor plan offset account”). These transfers reduce the amount of outstanding new vehicle floor plan notes payable that would otherwise accrue interest, while retaining the ability to transfer amounts from the floor plan offset account into our operating cash accounts within one to two days. As of December 31, 2013 and 2012 we had $44.3 million and $12.6 million, respectively in this floor plan offset account.
	The representations and covenants contained in the Restated Credit Agreement are customary for financing transactions of this nature including, among others, a requirement to comply with a minimum consolidated current ratio and consolidated fixed charge coverage ratio (each as defined in the Credit Agreement) and a maximum consolidated total lease adjusted leverage ratio, in each case as set out in the Credit Agreement. In addition, certain other covenants could restrict the Company's ability to incur additional debt, pay dividends or acquire or dispose of assets. See the “Covenants” section below under our "Long Term Debt" footnote.
	The Restated Credit Agreement also provides for events of default that are customary for financing transactions of this nature, including cross-defaults to other material indebtedness. In certain instances, an event of default under either the revolving credit facility or the used vehicle revolving floor plan facility could be, or result in, an event of default under the new vehicle revolving floor plan facility, and vice versa. Upon the occurrence of an event of default, the Company could be required to immediately repay all amounts outstanding under the applicable facility.
	The senior secured credit facilities are guaranteed by each existing, and will be guaranteed by each future, direct and indirect domestic subsidiary of the Company, other than, at our option, any immaterial subsidiary. The new vehicle revolving floor plan facility and the used vehicle revolving floor plan facility are each also guaranteed by the Company. The obligations under each of the revolving credit facility and the used vehicle revolving floor plan facility are collateralized by liens on substantially all of the present and future assets, other than real property, of the Company and the guarantors. The obligations under the new vehicle revolving floor plan facility are collateralized by liens on substantially all of the present and future assets, other than real property, of the borrowers under the new vehicle revolving floor plan facility.

	(a)	Does not include $9.2 million of unamortized premium that increases the book value of our 8.375% Notes ($1.1 million of which was classified within Current Portion of Long Term Debt as of December 31, 2013).
	8.375% Senior Subordinated Notes Add-On Issuance
	In June 2013, the Company completed an add-on issuance of $100.0 million aggregate principal amount of 8.375% Senior Subordinated Notes due 2020 (the “8.375% Notes”) at a price of 109.75% of par, plus accrued interest from May 15, 2013 (the "June 2013 Offering"). After deducting the initial purchasers' discounts and expenses of $2.3 million, we received net proceeds of approximately $108.3 million from this offering. The $9.8 million premium paid by the initial purchasers of the 8.375% Notes was recorded as a component of long-term debt on our Consolidated Balance Sheet and is being amortized as a reduction of interest expense over the remaining term of the 8.375% Notes. The capitalized costs associated with the issuance and sale of the 8.375% Notes are being amortized as an addition to interest expense over the remaining term of the 8.375% Notes. Including the amortization of the $9.8 million premium, and assuming the 8.375% Notes are outstanding until their maturity in November 2020, the effective interest rate on the 8.375% Notes issued in the June 2013 Offering will be 6.725%.
	Restated Credit Agreement
	As discussed above under our “Floor Plan Notes Payable” footnote, the Restated Credit Agreement includes a $175.0 million revolving credit facility with a $50.0 million sublimit for letters of credit. Under the revolving credit facility, subject to a borrowing base, we may (i) borrow up to $175.0 million, which amount may be expanded to up to $225.0 million in total credit availability upon satisfaction of certain conditions and (ii) request Bank of America to issue letters of credit on our behalf up to $50.0 million. Availability under the revolving credit facility is, in part, a function of our borrowing base. Availability is reduced on a dollar-for-dollar basis by the aggregate face amount of any outstanding letters of credit. Based on the borrowing base calculation and the $14.6 million of outstanding letters of credit as of December 31, 2013, our available borrowings were limited to $160.4 million as of December 31, 2013. As of December 31, 2013, we did not have any borrowings outstanding under the revolving credit facility. Proceeds from borrowings from time to time under the revolving credit facility may be used for, among other things, acquisitions, working capital and capital expenditures.
	Borrowings under the revolving credit facility bear interest, at our option, based on LIBOR plus 1.75% to 2.75% or the Base Rate plus 0.75% to 1.75%, in each case based on our total lease adjusted leverage ratio. The Base Rate is the highest of the (i) Bank of America, N.A. prime rate, (ii) Federal Funds rate plus 0.50%, and (iii) one month LIBOR plus 1.0%.
	In addition to the payment of interest on borrowings outstanding under the senior secured credit facilities, the Borrowers are required to pay a commitment fee on the total commitments under the senior secured credit facilities. The fees for commitments under the new vehicle revolving floor plan facility and the used vehicle revolving floor plan facility are 0.20% per annum and 0.25% per annum, respectively, and are payable on a quarterly basis.
	The representations and covenants contained in the Restated Credit Agreement are customary for financing transactions of this nature including, among others, a requirement to comply with a minimum consolidated current ratio and consolidated fixed charge coverage ratio (each as defined in the Restated Credit Agreement) and a maximum consolidated total lease adjusted leverage ratio, in each case as set out in the Restated Credit Agreement. In addition, certain other covenants could restrict the Company's ability to incur additional debt, pay dividends or acquire or dispose of assets. See “Covenants” below.
	Redemption of 7.625% Senior Subordinated Notes due 2017
	In September 2013, the Company redeemed all of the $143.2 million of its outstanding 7.625% Senior Subordinated Notes due 2017 (the "7.625% Notes"), using proceeds from the June 2013 Offering and borrowings under a real estate term loan credit agreement (the “Real Estate Credit Agreement”). In connection with the redemption, we recognized a $6.8 million loss, which is included in Loss on Extinguishment of Long-Term Debt on the accompanying Consolidated Statements of Income and consisted of (i) $3.6 million of premiums paid pursuant to the terms of the redemption, (ii) a $3.1 million write-off of unamortized debt issuance costs associated with the 7.625% Notes and (iii) $0.1 million of third-party costs associated with the redemption of the 7.625% Notes.
	Real Estate Credit Agreement
	In September 2013, the Company and certain of its subsidiaries entered into the Real Estate Credit Agreement with Bank of America, as lender. The Real Estate Credit Agreement provides for term loans to certain of the Company’s subsidiaries that are borrowers under the Real Estate Credit Agreement in an aggregate amount not to exceed $75.0 million, subject to customary terms and conditions. In September 2013 and October 2013, the Company borrowed aggregate amounts of $57.3 million and $17.7 million, respectively, under the Real Estate Credit Agreement. As described above, a portion of the proceeds from borrowings under the Real Estate Credit Agreement were used to pay a portion of the redemption price in connection with our redemption of the 7.625% Notes.
	Term loans under the Real Estate Credit Agreement bear interest, at the option of the Company, based on the LIBOR plus 2.50% or the Base Rate (as described below) plus 1.50%. The Base Rate is the highest of (i) the Federal Funds rate plus 0.50%, (ii) the Bank of America prime rate, and (iii) one month LIBOR plus 1.0%. The Company is required to make quarterly principal payments of 1.25% of the initial amount of each loan on a twenty year repayment schedule, with a balloon repayment of the outstanding principal amount of loans due in September 2023, subject to an earlier maturity if the Company’s existing senior secured credit facility matures or is not otherwise refinanced by certain dates. The Company can voluntarily prepay any loan in whole or in part any time without premium or penalty.
	The representations and covenants contained in the Real Estate Credit Agreement are customary for financing transactions of this nature, including, among others, a requirement to comply with a minimum consolidated current ratio, minimum consolidated fixed charge coverage ratio and maximum consolidated total lease adjusted leverage ratio, in each case as set out in the Real Estate Credit Agreement. In addition, certain other covenants could restrict the Company’s ability to incur additional debt, pay dividends or acquire or dispose of assets.
	The Real Estate Credit Agreement also contains events of default that are customary for financing transactions of this nature, including cross-defaults to other material indebtedness. Upon the occurrence of an event of default, the Company could be required to immediately repay all amounts outstanding under the Real Estate Credit Agreement.
	Borrowings under the Real Estate Credit Agreement are guaranteed by each operating dealership subsidiary of the Company whose real estate is financed under the Real Estate Credit Agreement, and collateralized by first priority liens, subject to certain permitted exceptions, on all of the real property financed thereunder.
	Mortgage Financing
	During the year ended December 31, 2013, we also entered into five fixed rate mortgage notes payable, which were collateralized by the related real estate at five of our owned dealership locations. The total initial principal amount of the mortgage notes payable was $52.5 million. In connection with our entrance into these mortgage notes payable, we paid approximately $0.5 million in debt issuance costs, which were capitalized and are being amortized to Other Interest Expense over the terms of the related mortgage notes payable. All five mortgages were financed by the captive finance companies affiliated with two of our manufacturing partners, and are classified as "Captive Mortgages" in the table below.
	We have a master loan agreement with Wells Fargo Bank, N.A. (“Wells Fargo”, and the master loan agreement being referred to as the “Master Loan Agreement”). As of December 31, 2013, our obligation under the Master Loan Agreement consists of a single mortgage for certain of our properties in St. Louis, Missouri.
	The Master Loan Agreement also contains customary representations and warranties and the guarantees under such agreements contain negative covenants, including, among other things, covenants not to, with permitted exceptions, (i) incur any additional debt; (ii) create any additional liens on the Property (as defined in the Master Loan Agreement); and (iii) enter into any sale-leaseback transactions in connection with the underlying properties.
	Below is a summary of our outstanding mortgage notes payable, the carrying values of the related collateralized real estate, and years of maturity as of December 31, 2013 and 2012:
			As of December 31, 2013						As of December 31, 2012

	Total		$	241.5		$	361.4		$	118.9	$	152.4
	Subordinated Note Repurchases
	Our board of directors has authorized us, from time to time, to repurchase various of our senior subordinated notes in open market purchases or privately negotiated transactions. The decision to repurchase our senior subordinated notes is dependent upon prevailing market conditions, our liquidity position, applicable limitations in any agreements to which we are a party, and other factors. Currently, the Restated Credit Agreement allows us to purchase at least $50.0 million of our debt securities per calendar year, subject to increase based on availability under our senior secured credit facilities. During 2013, we did not repurchase any of our senior subordinated notes.
	As of December 31, 2013, we had $300.0 million of our 8.375% subordinated notes outstanding.
	Stock Repurchase and Dividend Restrictions
	Pursuant to the indentures governing our 8.375% Notes and the agreements governing our senior secured credit facilities, our ability to repurchase shares of our common stock and pay cash dividends is limited to $88.3 million as of December 31, 2013, with an additional $10.0 million available to repurchase common stock only.
	Covenants
	We are subject to a number of covenants in our various debt and lease agreements, including those described below. We were in compliance with all of our covenants throughout 2013. Failure to comply with any of our debt covenants would constitute a default under the relevant debt agreements, which would entitle the lenders under such agreements to terminate our ability to borrow under the relevant agreements and accelerate our obligations to repay outstanding borrowings, if any, unless compliance with the covenants is waived. In many cases, defaults under one of our agreements could trigger cross default provisions in our other agreements. If we are unable to remain in compliance with our financial or other covenants, we would be required to seek waivers or modifications of our covenants from our lenders, or we would need to raise debt and/or equity financing or sell assets to generate proceeds sufficient to repay such debt. We cannot give any assurance that we would be able to successfully take any of these actions on terms, or at times, that may be necessary or desirable.
	The representations and covenants contained in the Restated Credit Agreement are customary for financing transactions of this nature including, among others, a requirement to comply with a minimum consolidated current ratio and consolidated fixed charge coverage ratio (each as defined in the Restated Credit Agreement) and a maximum consolidated total lease adjusted leverage ratio, in each case as set out in the Restated Credit Agreement. In addition, certain other covenants could restrict our ability to incur additional debt, pay dividends or acquire or dispose of assets.
	The Restated Credit Agreement also provides for events of default that are customary for financing transactions of this nature, including cross-defaults to other material indebtedness. In certain instances, an event of default under either the revolving credit facility or the used vehicle revolving floor plan facility could be, or result in, an event of default under the new vehicle floor plan facility, and vice versa. Upon the occurrence of an event of default, we could be required to immediately repay all amounts outstanding under the applicable facility.
	Our guarantees under the Master Loan Agreement also require compliance with certain financial covenants, including a consolidated current ratio, consolidated fixed charge coverage ratio and an adjusted net worth calculation.
	Certain of our lease agreements also require compliance with various financial covenants and incorporate by reference the
financial covenants set forth in the Restated Credit Agreement. A breach of any of these covenants could immediately give rise to certain landlord remedies under our various lease agreements, the most severe of which include the following: (a) termination of the applicable lease and/or other leases with the same or an affiliated landlord under a cross-default provision, (b) eviction from the premises; and (c) the landlord having a claim for various damages.
Asbury Automotive Group, Inc. is a holding company with no independent assets or operations. For all periods presented, our 8.375% Notes and our 7.625% Notes have been fully and unconditionally guaranteed, on a joint and several basis, by substantially all of our subsidiaries. Any subsidiaries which have not guaranteed such notes are “minor” (as defined in Rule 3-10(h) of Regulation S-X). As of December 31, 2013, there were no significant restrictions on the ability of our subsidiaries to distribute cash to us or our guarantor subsidiaries.

FINANCIAL INSTRUMENTS AND FAIR VALUE

In determining fair value, we use various valuation approaches, including market, income and/or cost approaches. Accounting standards establish a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the reliability of inputs as follows:

Level 1-Valuations based on quoted prices in active markets for identical assets or liabilities that we have the ability to access.

Level 2-Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly. Assets and liabilities utilizing Level 2 inputs include cash flow swap instruments and exchange-traded debt securities that are not actively traded or do not have a high trading volume.

Level 3-Valuations based on inputs that are unobservable and significant to the overall fair value measurement. Asset and liability measurements utilizing Level 3 inputs include those used in estimating fair value of non-financial assets and non-financial liabilities in purchase acquisitions and those used in assessing impairment of manufacturer franchise rights.

The availability of observable inputs can vary and is affected by a wide variety of factors. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment required to determine fair value is greatest for instruments categorized in Level 3. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is disclosed is determined based on the lowest level input that is significant to the fair value measurement.

Fair value is a market-based measure considered from the perspective of a market participant who holds the asset or owes the liability rather than an entity-specific measure. Therefore, even when market assumptions are not readily available, our assumptions are set to reflect those that market participants would use in pricing the asset or liability at the measurement date. We use inputs that are current as of the measurement date, including during periods of significant market fluctuations.

Financial instruments consist primarily of cash and cash equivalents, contracts-in-transit, accounts receivable, cash surrender value of corporate-owned life insurance policies, accounts payable, floor plan notes payable, subordinated long-term debt, mortgage notes payable and interest rate swap agreements. The carrying values of our financial instruments, with the exception of subordinated long-term debt, approximate fair value due to (i) their short-term nature, (ii) recently completed market transactions or (iii) existence of variable interest rates, which approximate market rates. The fair market value of our subordinated long-term debt is based on reported market prices which reflect Level 2 inputs. Level 2 inputs are valuations based on quoted market prices in markets that are not active or do not have a high trading volume. A summary of the carrying values and fair values of our 8.375% Notes and our 7.625% Notes is as follows:

In November 2013, we entered into an interest rate swap agreement with a notional principal amount of $75.0 million. This swap was designed to provide a hedge against changes in variable rate cash flows through maturity in September 2023. The notional value of this swap is reducing over its remaining term to $38.7 million at maturity.

We are also party to an interest rate swap agreement that had a notional principal amount of $18.4 million as of December 31, 2013. This swap is designed to provide a hedge against changes in variable interest rate cash flows through maturity in October 2015. The notional value of this swap is reducing over the remaining term to $16.1 million at maturity.

Both of our interest rate swaps qualify for cash flow hedge accounting treatment and do not, and will not, contain any ineffectiveness.

Valuation Techniques

The fair value of cash flow swaps is calculated as the present value of expected future cash flows, determined on the basis of forward interest rates and present value factors. As such, the carrying amounts for these swaps are designated to be Level 2 fair values and totaled $0.3 million and $(0.6) million as of December 31, 2013 and 2012, respectively. The carrying value of these swaps is included in Other Long-Term Liabilities, Other Long-Term Assets and Other Current Liabilities on the accompanying Consolidated Balance Sheet as of December 31, 2013.

The fair value of assets held for sale used to determine the impairment expenses we incurred in 2012 and 2011 were determined with the assistance of third-party broker opinions of value and third-party desktop appraisals and are designated to be Level 2 fair values.

Other Financial Instruments

In connection with the sale of our 3% Convertible Notes in March 2007, we entered into separate warrant transactions whereby we sold to Goldman, Sachs & Co. and Deutsche Bank AG, London Branch (collectively, the “Counterparties”) warrants to acquire, subject to customary anti-dilution adjustments, shares of our common stock at an initial strike price of $45.09 per share, which was a 62.50% premium over the market price of our common stock at the time of pricing. As of March 31, 2013, the strike price was $44.74 as a result of certain dividend payments. These warrants expired in a series of tranches through April 2013.

	During the years ended December 31, 2013, 2012 and 2011, we made interest payments, including amounts capitalized, totaling $52.4 million, $46.1 million and $52.3 million, respectively. Included in these interest payments are $12.2 million, $10.5 million and $11.0 million, of floor plan interest payments for the years ended December 31, 2013, 2012 and 2011, respectively.
	During the years ended December 31, 2013, 2012 and 2011, we made income tax payments, net of refunds received, totaling $60.1 million, $32.8 million and $15.4 million, respectively.
	During the years ended December 31, 2013, 2012 and 2011, we sold $13.8 million, $18.7 million and $22.6 million, respectively, of trade receivables, at a total discount of $0.3 million, $0.4 million and $0.6 million, respectively.

	Until February 2012, we sponsored the Asbury Automotive Wealth Accumulation Plan (the “Deferred Compensation Plan”) wherein eligible employees, generally those at senior levels, could elect to defer a portion of their annual compensation. In February 2012, our Board of Directors elected to terminate the Deferred Compensation Plan. During the year ended December 31, 2013, we (i) received a $7.8 million lump sum distribution as a result of the termination of the Deferred Compensation Plan and (ii) used these proceeds to relieve our corresponding $7.8 million total liability to the Deferred Compensation Plan's participants.

Leases Obligations	'
	LEASE OBLIGATIONS
	We lease various facilities, real estate and equipment primarily under operating lease agreements, most of which have remaining terms from one to twenty years. Certain of our leases contain renewal options and rent escalation clauses. We record rent expense on a straight-line basis over the life of the lease for lease agreements where the rent escalates at fixed rates over time. Rent expense from continuing operations totaled $32.9 million, $35.5 million and $36.3 million for the years ended December 31, 2013, 2012 and 2011, respectively. As of December 31, 2013, we had one significant capital lease obligation totaling approximately $3.7 million. This lease was entered into in 2011, and is being amortized over 20 years.
	During the year ended December 31, 2013, we entered into four transactions in which we purchased various previously leased real estate for a total purchase price of $35.7 million. These transactions included the termination of the related lease obligations, resulting in losses of $5.5 million, which is included in Other Operating Expense, net in our Consolidated Statement of Income for the year ended December 31, 2013.
	During the year ended December 31, 2012, we entered into four transactions in which we purchased various previously
	leased real estate for a total purchase price of $17.5 million. These transactions included the termination of the related lease
	obligations, resulting in losses of $1.8 million, which is included in Other Operating Expense, net on our Consolidated Statement of Income for year ended December 31, 2012.
	During the year ended December 31, 2011, we entered into two transactions in which we purchased various previously leased real estate for a total purchase price of $30.3 million. One of the transactions included a termination of a lease obligation for property not currently used in our operations, resulting in a loss of $1.0 million, which is included in Other Operating Expense, net on our Consolidated Statement of Income for year ended December 31, 2011.
	Future minimum payments under long-term, non-cancellable operating leases as of December 31, 2013, are as follows:
		Total
		(In millions)
	2014	$	31.3
	2015	29.3

	Total minimum lease payments	$	230.8
	Certain of our lease agreements include financial covenants and incorporate by reference the financial covenants set forth in the Restated Credit Agreement. A breach of any of these covenants could immediately give rise to certain landlord remedies under our various lease agreements, the most severe of which include the following: (a) termination of the applicable lease and/or other leases with the same or an affiliated landlord under a cross-default provision, (b) eviction from the premises; and (c) the landlord having a claim for various damages.

	COMMITMENTS AND CONTINGENCIES
	Our dealerships are party to dealer and framework agreements with applicable vehicle manufacturers.  In accordance with these agreements, each dealership has certain rights and is subject to restrictions typical in the industry. The ability of these manufacturers to influence the operations of the dealerships or the loss of any of these agreements could have a materially negative impact on our operating results.
	In some instances, manufacturers may have the right, and may direct us, to implement costly capital improvements to dealerships as a condition to entering into, renewing or extending franchise agreements with them. Manufacturers also typically require that their franchises meet specific standards of appearance. These factors, either alone or in combination, could cause us to use our financial resources on capital projects that we might not have planned for or otherwise determined to undertake.
	From time to time, we and our dealerships are or may become involved in various claims relating to, and arising out of, our business and our operations.  These claims may involve, but not be limited to, financial and other audits by vehicle manufacturers, lenders and certain federal, state and local government authorities, which have historically related primarily to (a) incentive and warranty payments received from vehicle manufacturers, or allegations of violations of manufacturer agreements or policies, (b) compliance with lender rules and covenants and (c) payments made to government authorities relating to federal, state and local taxes, as well as compliance with other government regulations. Claims may also arise through litigation, government proceedings and other dispute resolution processes.  Such claims, including class actions, could relate to, but may not be limited to, the practice of charging administrative fees and other fees and commissions, employment-related matters, truth-in-lending and other dealer assisted financing obligations, contractual disputes, actions brought by governmental authorities and other matters. We evaluate pending and threatened claims and establish loss contingency reserves based upon outcomes we currently believe to be probable and reasonably estimable.
	We believe we have adequately accrued for the potential impact of loss contingencies that are probable and reasonably estimable.  Based on our review of the various types of claims currently known to us, there is no indication of material reasonably possible losses in excess of amounts accrued in the aggregate.  We currently do not anticipate that any known claim will materially adversely affect our financial condition, liquidity or results of operations.  However, the outcome of any matter cannot be predicted with certainty, and an unfavorable resolution of one or more matters presently known or arising in the future could have a material adverse effect on our financial condition, liquidity or results of operations.
	A significant portion of our business involves the sale of vehicles, parts or vehicles composed of parts that are manufactured outside the United States. As a result, our operations are subject to customary risks of importing merchandise, including fluctuations in the relative values of currencies, import duties, exchange controls, trade restrictions, work stoppages and general political and socio-economic conditions in foreign countries. The United States or the countries from which our products are imported may, from time to time, impose new quotas, duties, tariffs or other restrictions, or adjust presently prevailing quotas, duties or tariffs, which may affect our operations and our ability to purchase imported vehicles and/or parts at reasonable prices.
	Substantially all of our facilities are subject to federal, state and local provisions regarding the discharge of materials into the environment. Compliance with these provisions has not had, nor do we expect such compliance to have, any material effect upon our capital expenditures, net earnings, financial condition, liquidity or competitive position. We believe that our current practices and procedures for the control and disposition of such materials comply with applicable federal, state and local requirements. No assurances can be provided, however, that future laws or regulations, or changes in existing laws or regulations, would not require us to expend significant resources in order to comply therewith.
	We had $14.6 million of letters of credit outstanding as of December 31, 2013, which are required by certain of our insurance providers. In addition, as of December 31, 2013, we maintained a $5.0 million surety bond line in the ordinary course of our business. Our letters of credit and surety bond line are considered to be off balance sheet arrangements.
	Our other material commitments include (i) floor plan notes payable, (ii) operating leases, (iii) long-term debt and (iv) interest on long-term debt, as described elsewhere herein.

	During the years ended December 31, 2013, 2012 and 2011, we were party to certain agreements with a former member of our board of directors and a current member of our management team. These agreements primarily involved long−term operating leases of dealership facilities. We believe that the rental transactions related to these agreements were on terms comparable to those that could be obtained from unaffiliated third parties. For the years ended December 31, 2013, 2012 and 2011, we made rental payments totaling $2.2 million, $2.2 million and $2.3 million, respectively, to these individuals or entities controlled by these individuals.

Share-based Compensation and Employee Benefit Plans	'
	SHARE-BASED COMPENSATION AND EMPLOYEE BENEFIT PLANS
	We have established three share-based compensation plans (the “Plans”) under which we have historically granted non-qualified stock options, performance share units, restricted share units and shares of restricted stock to our directors, officers and employees at fair market value on the date of the grant. Stock options generally vest ratably over three years from the date of grant and expire ten years from the date of grant. Performance share units vest after three years or ratably over three years from the date of grant for performance share units granted to date. The actual number of shares earned by a holder of performance share units may range from 0% to 150% of the target number of shares to be granted to the holder, depending on the achievement of certain performance criteria over a defined period of time. Restricted stock provides the holder voting and forfeitable dividend rights prior to vesting. Restricted stock grants to our officers and employees vest ratably over three years from the date of grant, while restricted stock grants to members of our board of directors vest immediately upon the date of grant. Restricted share units vest ratably over three years from the date of grant. We have granted a total of 5.8 million non-qualified stock options, 1.6 million performance share units, 1.3 million shares of restricted stock and 0.1 million of restricted share units. In addition, there were approximately 1.3 million share-based awards available for grant under our share-based compensation plans as of December 31, 2013.
	We issue new shares of our common stock upon the exercise of stock options or vesting of performance share units, restricted stock or restricted share units. In addition, in connection with the vesting of performance share units, restricted stock or restricted share units, we expect to repurchase a portion of the shares issued equal to the amount of employee income tax withholding.
	The fair value of each option award was estimated on the date of grant using the Black Scholes option valuation model. The fair value of each performance share unit and restricted stock award was calculated using the closing market price of our common stock on the date of grant. Expected volatilities are based on the historical volatility of our common stock. We use historical data to estimate the rate of option exercises and employee turnover within the valuation model. The expected term of options granted represents the period of time that the related options are expected to be outstanding. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant.
	We have recognized $9.0 million ($3.5 million tax benefit), $7.1 million ($2.7 million tax benefit) and $8.8 million ($3.4 million tax benefit) in stock-based compensation expense for the years ended December 31, 2013, 2012 and 2011, respectively. As of December 31, 2013, there was $9.6 million of total unrecognized share-based compensation expense related to non-vested share-based awards granted under the Plans, and we expect to recognize $5.2 million of this expense in 2014, $2.5 million in 2015 and $1.7 million in 2016.
	A summary of options outstanding and exercisable under the Plans as of December 31, 2013, changes during the year then ended and changes during the years ended December 31, 2012 and 2011 is presented below:

Employee Retirement Plan
We sponsor the Asbury Automotive Retirement Savings Plan (the “Retirement Savings Plan”), a 401(k) plan, for eligible employees. Employees are eligible to participate in the Retirement Savings Plan on or after 90 days of service to the Company. Employees electing to participate in the Retirement Savings Plan may contribute up to 75% of their annual eligible  compensation. IRS rules limited total participant contributions during 2013 to $17,500 or $23,000 if age 50 or more; however, we limit participant contributions for employees considered Highly Compensated Employees with an annual salary or base salary equal to or greater than $115,000 to $10,000 per year or $15,500 if age 50 or more. After one year of employment, we match 37.5% of employees' contributions up to 4% of their  eligible compensation, with a maximum match of $1,725 per participant. Beginning on January 1, 2009, we suspended our matching contributions for Highly Compensated Employees with an annual salary equal to or greater than $115,000. Employer contributions vest by graded schedule over four years after the date of hire. Expenses from continuing operations related to employer matching contributions totaled $1.1 million, $0.5 million and $1.0 million for the years ended December 31, 2013, 2012 and 2011, respectively.
Deferred Compensation Plan
We have historically sponsored the Deferred Compensation Plan wherein eligible employees, generally those at senior levels, may elect to defer a portion of their annual compensation. In February 2012, our Board of Directors elected to terminate the Deferred Compensation Plan. During 2013, we (i) received a $7.8 million lump sum distribution as a result of the termination of the Deferred Compensation Plan and (ii) used these proceeds to relieve our corresponding $7.8 million total liability to the Deferred Compensation Plan's participants.

Segment Reporting, Policy [Policy Text Block]	'
	Segment Reporting
	We have determined that as a result of how we internally view our business, regularly review our financial data and operating metrics and allocate resources that we operate in one segment, automotive retail. Our Chief Operating Decision Maker is our Chief Executive Officer who manages the business, regularly reviews financial information and allocates resources on a consolidated basis. Our dealerships are components of our automotive retail segment and, therefore, are not segments themselves.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	'
	Business and Credit Concentration Risk
	Financial instruments, which potentially subject us to concentration of credit risk, consist principally of cash deposits. We maintain cash balances at financial institutions with strong credit ratings. Generally, amounts invested with financial institutions are in excess of FDIC insurance limits.
	We have substantial debt service obligations. As of December 31, 2013, we had total debt of $554.4 million, excluding floor plan notes payable on our accompanying Consolidated Balance Sheet. In addition, we and our subsidiaries have the ability to obtain additional debt from time to time to finance acquisitions, real property purchases, capital expenditures or for other purposes, although such borrowings are subject to the restrictions contained in the credit agreement governing our senior secured credit facilities and the indenture governing our 8.375% Senior Subordinated Notes due 2020 (the "8.375% Notes"). We will have substantial debt service obligations, consisting of required cash payments of principal and interest, for the foreseeable future.
	We are subject to operating and financial restrictions and covenants in certain of our leases and in our debt instruments, including the credit agreement governing our senior secured credit facilities, the 8.375% Notes indenture and the credit agreements covering our mortgage obligations. These agreements contain restrictions on, among other things, our ability to incur additional indebtedness, to create liens or other encumbrances, and to make certain payments (including dividends and repurchases of our shares and investments). These agreements may also require us to maintain compliance with certain financial and other ratios. Our failure to comply with any of these covenants in the future would constitute a default under the relevant agreement, which would, depending on the relevant agreement, (i) entitle the creditors under such agreement to terminate our ability to borrow under the relevant agreement and accelerate our obligations to repay outstanding borrowings; (ii) require us to apply our available cash to repay these borrowings; (iii) entitle the creditors under such agreement to foreclose on the property securing the relevant indebtedness; and/or (iv) prevent us from making debt service payments on certain of our other indebtedness, any of which would have a material adverse effect on our business, financial condition or results of operations. In many cases, a default under one of our debt or mortgage, agreements could trigger cross default provisions in one or more of our other debt or mortgages.
	A number of our dealerships are located on properties that we lease. Each of the leases governing such properties has certain covenants with which we must comply. If we fail to comply with the covenants under our leases, the respective landlords could terminate the leases and seek damages from us.
	Concentrations of credit risk with respect to contracts-in-transit and accounts receivable are limited primarily to automotive manufacturers and financial institutions. Credit risk arising from receivables from commercial customers is minimal due to the large number of customers comprising our customer base.
	A significant portion of our new vehicle sales are derived from a l
Income Tax, Policy [Policy Text Block]	'
	Income Taxes
	We use the liability method to account for income taxes. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax basis using currently enacted tax rates. The effect on deferred assets and liabilities of a change in tax rates is recognized in income in the period when the change is enacted. Deferred tax assets are reduced by a valuation allowance when it is more likely than not that some portion or all the deferred tax assets will not be realized.
Business Combinations Policy [Policy Text Block]	'
	Acquisitions
	Acquisitions are accounted for under the purchase method of accounting and the assets acquired and liabilities assumed are recorded at their fair value as of the acquisition dates. The operations of acquired dealerships are included in the accompanying Consolidated Statements of Income commencing on the date of acquisition.
Basis of Presentation	'
	Basis of Presentation
	The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”), and reflect the consolidated accounts of Asbury Automotive Group, Inc. and our wholly owned subsidiaries. All intercompany transactions have been eliminated in consolidation. In addition, certain reclassifications of amounts previously reported have been made to the accompanying Consolidated Financial Statements in order to conform to current presentation.
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the periods presented. Actual results could differ materially from these estimates. Estimates and assumptions are reviewed quarterly and the effects of any revisions are reflected in the consolidated financial statements in the period they are determined to be necessary. Significant estimates made in the accompanying consolidated financial statements include, but are not limited to, those relating to inventory valuation reserves, reserves for chargebacks against revenue recognized from the sale of finance and insurance products, certain assumptions related to intangible and long-lived assets, reserves for insurance programs, reserves for certain legal or similar proceedings relating to our business operations, realization of deferred tax assets and reserves for estimated tax liabilities.

	Contracts-In-Transit
	Contracts-in-transit represent receivables from third-party finance companies for the portion of new and used vehicle purchase price financed by customers through sources arranged by us. Amounts due from contracts-in-transit are generally collected within two weeks following the date of sale of the related vehicle.
Revenue Recognition	'
	Revenue Recognition
	Revenue from the sale of new and used vehicles (which excludes sales tax) is recognized upon the latest of delivery, passage of title, signing of the sales contract or approval of financing. Revenue from the sale of parts, service and collision repair work (which excludes sales tax) is recognized upon delivery of parts to the customer or at the time vehicle service or repair work is completed, as applicable. Manufacturer incentives and rebates, including manufacturer holdbacks, floor plan interest assistance and certain advertising assistance, are recognized as a reduction of new vehicle cost of sales at the time the related vehicles are sold.
	We receive commissions from third-party lending and insurance institutions for arranging customer financing and from the sale of vehicle service contracts, credit life insurance and disability insurance, and other insurance, to customers (collectively “F&I”). We may be charged back (“chargebacks”) for F&I commissions in the event a contract is prepaid, defaulted upon or terminated. F&I commissions are recorded at the time a vehicle is sold and a reserve for future chargebacks is established based on historical chargeback experience and the termination provisions of the applicable contract. F&I commissions, net of estimated future chargebacks, are included in Finance and Insurance, net in the accompanying Consolidated Statements of Income.
Earnings per Common Share	'
	Earnings per Common Share
	Basic earnings per common share is computed by dividing net income by the weighted-average common shares outstanding during the period. Diluted earnings per common share is computed by dividing net income by the weighted-average common shares and common share equivalents outstanding during the period. For all periods presented, there were no adjustments to the numerator necessary to compute diluted earnings per share.
Discontinued Operations	'
	Discontinued Operations
	Certain amounts reflected in the accompanying Consolidated Balance Sheets have been classified as Assets Held for Sale or Liabilities Associated with Assets Held for Sale, with such classification beginning on the date that the assets and associated liabilities were first considered held for sale.
	We report franchises and ancillary businesses as discontinued operations when it is evident that the operations and cash flows of a franchise or ancillary business being actively marketed for sale will be eliminated from our on-going operations and that we will not have any significant continuing involvement in its operations. We do not classify franchises as discontinued operations if we believe that the cash flows generated by the franchise will be replaced by expanded operations of our remaining franchises within the respective local market area.
	Amounts in the accompanying Consolidated Statements of Income for the years ended December 31, 2012 and December 31, 2011 have been reclassified to reflect the results of franchises sold or closed during 2013 as if we had classified those franchises as discontinued operations for all years presented.
Statements of Cash Flows	'
	Statements of Cash Flows
	Borrowings and repayments of floor plan notes payable to a lender unaffiliated with the manufacturer from which we purchase a particular new vehicle ("Non-Trade"), and all floor plan notes payable relating to pre-owned vehicles (together referred to as "Floor Plan Notes Payable-Non-Trade"), are classified as financing activities on the accompanying Consolidated Statements of Cash Flows, with borrowings reflected separately from repayments. The net change in floor plan notes payable to a lender affiliated with the manufacturer from which we purchase a particular new vehicle (collectively referred to as “Floor Plan Notes Payable - Trade”) is classified as an operating activity on the accompanying Consolidated Statements of Cash Flows. Borrowings of floor plan notes payable associated with inventory acquired in connection with all acquisitions are classified as a financing activity. Cash flows related to floor plan notes payable included in operating activities differ from cash flows related to floor plan notes payable included in financing activities only to the extent that the former are payable to a lender affiliated with the manufacturer from which we purchased the related inventory, while the latter are payable to a lender not affiliated with the manufacturer from which we purchased the related inventory. Repayments of Floor Plan Notes Payable - Trade associated with divestitures are classified as an operating activity. Repayments of Floor Plan Notes Payable - Non-Trade associated with divestitures are classified as a financing activity.
	Loaner vehicles account for a significant portion of Other Current Assets. We acquire loaner vehicles either with available cash or through borrowings from manufacturer affiliated lenders. Loaner vehicles are initially used by our service department for only a short period of time (typically six to twelve months) before we seek to sell them. Therefore, we classify the acquisition of loaner vehicles and the related borrowings and repayments as operating activities in the accompanying Consolidated Statements of Cash Flows. The cash outflow to acquire loaner vehicles is presented in Other Current Assets in the accompanying Consolidated Statements of Cash Flows. Borrowings and repayments of loaner vehicle notes payable are presented in Accounts Payable and Accrued Liabilities in the accompanying Consolidated Statements of Cash Flows. When loaner vehicles are taken out of loaner status they are transferred to used vehicle inventory, which is reflected as a non-cash transfer in the accompanying Consolidated Statements of Cash Flows. The cash inflow from the sale of loaner vehicles is reflected in Inventories in the accompanying Consolidated Statements of Cash Flows.
Inventory, Policy [Policy Text Block]	'
	Inventories
	Inventories are stated at the lower of cost or market. We use the specific identification method to value vehicle inventories and the “first-in, first-out” method (“FIFO”) to account for our parts inventories. We maintain a reserve for specific used vehicles where cost basis exceeds market value. Our new vehicle sales histories have indicated that the vast majority of the new vehicles we sell are sold for, or in excess of, our cost to purchase those vehicles. Therefore, we generally do not maintain a reserve for specific new vehicle inventory. In assessing lower of cost or market for used vehicles, we consider (i) the aging of our used vehicles, (ii) historical sales experience of used vehicles and (iii) current market conditions and trends for used vehicles. We also review and consider the following metrics related to used vehicle sales (both on a recent and longer-term historical basis): (a) days of supply in our used vehicle inventory, (b) used vehicle units sold at less than original cost as a percentage of total used vehicles sold and (c) average vehicle selling price of used vehicle units sold at less than original cost. We then determine the appropriate level of reserve required to reduce our used vehicle inventory to the lower of cost or market, and record the resulting adjustment in the period in which we determine a loss has occurred. The level of reserve determined to be appropriate for each reporting period is considered to be a permanent inventory write-down and therefore is only released upon the sale of the related inventory.
	We receive assistance from certain automobile manufacturers in the form of advertising and interest credits. Manufacturer advertising credits that are reimbursements of costs associated with specific advertising programs are recognized as a reduction of advertising expense in the period they are earned. All other manufacturer advertising and interest credits are accounted for as purchase discounts and are recorded as a reduction of inventory and recognized as a reduction to New Vehicle Cost of Sales in the accompanying Consolidated Statements of Income in the period the related vehicle is sold.
Property, Plant and Equipment, Policy [Policy Text Block]	'
	Property and Equipment
	Property and equipment are recorded at cost and depreciated using the straight-line method over their estimated useful lives. Depreciation is included in Depreciation and Amortization and Discontinued Operations, net of tax, on the accompanying Consolidated Statements of Income. Leasehold improvements are capitalized and amortized over the lesser of the life of the lease or the useful life of the related asset. The ranges of estimated useful lives are as follows (in years):
	Buildings and improvements	Oct-40
	Machinery and equipment	10-May
	Furniture and fixtures	10-Mar
	Company vehicles	5-Mar
	Expenditures for major additions or improvements, which extend the useful lives of assets, are capitalized. Minor replacements, maintenance and repairs, which do not improve or extend the lives of such assets, are expensed as incurred.
	We review property and equipment for impairment whenever events or changes in circumstances indicate the carrying value may not be recoverable. When we test our long-lived assets for impairment, we first compare the carrying amount of the underlying assets to their net recoverable value by reviewing the undiscounted cash flows expected to result from the use and eventual disposition of the underlying assets. If the carrying amount of the underlying assets is less than their net recoverable value, then we calculate an impairment equal to the excess of the carrying amount over the fair market value, and the impairment loss would be charged to operations in the period identified. As a result of impairment tests conducted in 2013, 2012 and 2011, we recorded only immaterial impairments of certain of our property and equipment in those periods.
	We capitalize interest on borrowings during the active construction period of capital projects. Capitalized interest is added to the cost of the assets and is depreciated over the estimated useful lives of the assets.
Goodwill and Intangible Assets, Policy [Policy Text Block]	'
	Goodwill and Other Intangible Assets
	Goodwill represents the excess cost of the businesses acquired over the fair market value of the identifiable net assets. We have determined that, based on how we integrate acquisitions into our business, how the components of our business share resources and interact with one another, and the fact that all components are economically similar, we qualify as a single reporting unit for purposes of testing goodwill for impairment.
	Our only significant identifiable intangible assets, other than goodwill, are rights under franchise agreements with manufacturers, which are recorded at an individual dealership level. The fair market value of our manufacturer franchise rights, which are included in Other Long Term Assets on the accompanying Consolidated Balance Sheets, is determined at the acquisition date through discounting the projected cash flows specific to each franchise. We have determined that manufacturer franchise rights have an indefinite life as there are no economic, contractual or other factors that limit their useful lives and they are expected to generate cash flows indefinitely due to the historically long lives of the manufacturers’ brand names. Furthermore, to the extent that any agreements evidencing our manufacturer franchise rights would expire, we expect that we would be able to renew those agreements in the ordinary course of business.
	We do not amortize goodwill and other intangible assets that are deemed to have indefinite lives. We review goodwill and manufacturer franchise rights for impairment annually as of October 1st of each year, or more often if events or circumstances indicate that impairment may have occurred. We are subject to financial statement risk to the extent that manufacturer franchise rights become impaired due to decreases in fair market value of our individual franchises or to the extent that goodwill becomes impaired due to decreases in the fair market value of our automotive retail business.
	We completed our annual intangible impairment tests as of October 1, 2013, and no impairment of goodwill or other intangible assets was recognized as a result of such tests.
Deferred Charges, Policy [Policy Text Block]	'
	Debt Issuance Costs
	Debt issuance costs are capitalized and included in Other Current Assets and Other Long-Term Assets in the accompanying Consolidated Balance Sheets. Debt issuance costs are amortized to Other Interest Expense, net and Floor Plan Interest Expense in the accompanying Consolidated Statements of Income through maturity using either the effective interest method or straight line method.
Derivatives, Policy [Policy Text Block]	'
	Derivative Instruments and Hedging Activities
	From time to time, we utilize derivative financial instruments to manage our capital structure and interest rate risk. The types of risks hedged are those relating to the variability of cash flows and changes in the fair value of our financial instruments caused by movements in interest rates. We document our risk management strategy and assess hedge effectiveness at the inception and during the term of each hedge. Derivatives are reported at fair value on the accompanying Consolidated Balance Sheets.
	The effective portion of the gain or loss on our cash flow hedges is reported as a component of Accumulated Other Comprehensive Loss on the accompanying Consolidated Balance Sheets and reclassified to Swap Interest Expense in the accompanying Consolidated Statements of Income in the same period during which the hedged transaction affects earnings.
	Measurements of hedge effectiveness are based on comparisons between the gains or losses of the actual interest rate swaps and the gains or losses of hypothetical interest rate swaps, which have the same critical terms of the defined hedged items. Ineffective portions of these interest rate swaps are reported as a component of interest expense in the accompanying Consolidated Statements of Income.
Self Insurance, Policy [Policy Text Block]	'
	Insurance
	We are self insured for employee medical claims and maintain stop loss insurance for large-dollar individual claims. We have large deductible insurance programs for workers compensation, property and general liability claims. We maintain and review our claim and loss history to assist in assessing our expected future liability for these claims. We also use professional service providers, such as account administrators and actuaries, to help us accumulate and assess this information.
Consolidation, Policy [Policy Text Block]	'
	Internal Profit
	Revenues and expenses associated with the internal work performed by our parts and service departments on new and used vehicle inventory are eliminated in consolidation. The gross profit earned by our parts and service departments for internal work performed is included as a reduction of Parts and Service Cost of Sales on the accompanying Consolidated Statements of Income. The costs incurred by our new and used vehicle departments for work performed by our parts and service departments is included in either New Vehicle Cost of Sales or Used Vehicle Cost of Sales on the accompanying Consolidated Statements of Income, depending on the classification of the vehicle serviced. We maintain a reserve to eliminate the internal profit on vehicles that have not been sold.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	'
	Share-Based Compensation
	We record share-based compensation expense under the fair value method on a straight-line basis over the vesting period, unless the awards are subject to performance conditions, in which case we recognize the expense over the requisite service period of each separate vesting tranche.
Advertising Costs, Policy [Policy Text Block]	'
	Advertising
	We expense costs of advertising as incurred and production costs when the advertising initially takes place, net of certain advertising credits and other discounts. Advertising expense from continuing operations totaled $32.8 million, $27.8 million and $25.3 million for the years ended December 31, 2013, 2012 and 2011, net of earned advertising credits and volume discounts of $13.5 million, $11.8 million and $9.5 million, respectively, and is included in Selling, General and Administrative expense in the accompanying Consolidated Statements of Income.
