Debt Disclosure [Abstract]
Floor Plan Notes Payable	FLOOR PLAN NOTES PAYABLE We and certain of our subsidiaries are party to a credit agreement with Bank of America, N.A. (“Bank of America”), as administrative agent, and the lenders party thereto (the “Credit Agreement”). The Credit Agreement provides 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 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 Credit Agreement. Subject to the compliance with certain conditions, the 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 $225.0 million in the aggregate without lender consent and also subject to the compliance with certain conditions. The senior secured credit facilities mature, and all amounts outstanding thereunder will be due and payable, on October 14, 2016. Borrowings under our new vehicle floor plan facility bear interest, at our option, based on LIBOR plus 1.5% or the Base Rate plus 0.50%. Borrowings under the used vehicle revolving floor plan facility bear interest, at our option, based on LIBOR plus 1.75% or the Base Rate plus 0.75%. 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.” Upon our entrance into the Credit Agreement, 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, 2012, we had $55.1 million of floor plan notes payable—trade and $507.0 million of floor plan notes payable—non-trade outstanding, including amounts classified as Liabilities Associated with Assets Held for Sale. As of December 31, 2012 and 2011, we had a total of $562.1 million and $434.0 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 new 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, 2012, we had $12.6 million in this floor plan offset account. The representations and covenants contained in the 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 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.
