     This PURCHASE AGREEMENT (the “Agreement”) dated as of September 14, 2006 is by and between PENSKE CORPORATION, a Delaware corporation (the “Purchaser” or “Penske”), and [Seller], having an address on the signature page (the “Seller”).

RECITALS

     WHEREAS, the Seller desires to sell to the Purchaser, and the Purchaser desires to purchase from the Seller, one-half of the shares of Common Stock, par value $0.0001 per share, of United Auto Group, Inc., a Delaware corporation (the “Company”) (the “Shares) that are to be distributed to Seller in Seller’s capacity as a member of Penske Associates, LLC, a Delaware limited liability company (“Associates”) in September, 2006 (the “Distribution”), for a purchase price determined in accordance with this Agreement;

     NOW, THEREFORE, in consideration of the mutual promises and of the mutual covenants, representations and warranties and obligations hereinafter set forth, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows:

ARTICLE I

SALE AND PURCHASE OF SECURITIES

     Section 1.1 The Purchase. At the Closing, subject to the terms and conditions hereof, the Purchaser shall purchase from the Seller, and the Seller shall sell to Purchaser one-half of the shares of Common Stock of the Company received by the Seller in the Distribution (the “Securities”) at a purchase price per share and an aggregate purchase price determined in accordance with Section 1.2 (the “Purchase Price”) payable at the Closing (the “Purchase”).

     Section 1.2 Purchase Price. The purchase price of each Share shall be the average of the daily closing sales prices of the Common Stock of the Company for the twenty (20) consecutive trading days as reported on the New York Stock Exchange immediately preceding September 12, 2006 (the “Current Market Value”). The aggregate purchase price shall be the amount determined by multiplying the number of shares of Common Stock of the Company being sold to the Purchaser by the Current Market Value (the “Aggregate Purchase Price”).

     Section 1.3 The Closing. The closing of the sale and purchase of the Securities (the “Closing”) shall take place at the offices of Penske Corporation, ▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇, at 9:00 a.m., New York time, as soon as practicable, but in any event not earlier than September 12, 2006 nor later than five Business Days thereafter, and, in any event, only upon the satisfaction or waiver of the conditions contained in Article IV, unless the parties otherwise agree in writing (the “Closing Date”).

     Section 1.4 Payment and Payment Instructions. The Seller shall receive the Purchase Price from the Purchaser at the Closing in the form of that number of shares of Penske Corporation Class C Non-voting common stock ($.01 par value) (the “Stock”) resulting from the following fraction:

Aggregate Purchase Price
Fair Market Price of a share of the Stock

     No fractional shares of the Stock shall be issued. The Seller shall receive in cash the value of the fractional share of the Stock based upon the Fair Market Price of a single share of the Stock.

     Section 1.5 Actions at the Closing. At the Closing, the following actions shall occur (the “Closing Actions”):

     (a) The Seller shall deliver to the Purchaser the Securities, free and clear of liens and encumbrances thereon.

     (b) The Purchaser shall pay the Aggregate Purchase Price to the Seller by good check and the shares of the Stock determined in accordance with Section 1.4 within three (3) Business Days of the Closing.

     Section 1.6 Legend.

     (a) The parties hereby acknowledge and agree that each of the certificates representing the Securities and the Stock shall include the following legend and any other legend required by law:

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) AND MAY BE OFFERED OR SOLD ONLY IF REGISTERED UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

     (b) The requirement that the above securities legend be placed upon certificates evidencing shares of the Stock shall cease and terminate upon the earliest of the following events: (i) when such shares are transferred in an underwritten public offering, (ii) when such shares are transferred pursuant to

Rule 144 in compliance with the Securities Act or (iii) when such shares are transferred in any other transaction if the seller delivers to Penske, if applicable, an opinion of its counsel, which counsel and opinion shall be reasonably satisfactory to the Company, or a “no-action” letter from the staff of the Securities and Exchange Commission, in either case to the effect that such legend is no longer necessary in order to protect Penske, if applicable, against a violation by it of the Securities Act upon any sale or other disposition of such shares without registration thereunder. Upon the consummation of any event requiring the removal of a legend hereunder, Penske, if applicable, upon the surrender of certificates containing such legend, shall, at its own expense, deliver to the holder of any such shares as to which the requirement for such legend shall have terminated, one or more new certificates evidencing such shares not bearing such legend.

ARTICLE II

REPRESENTATIONS & WARRANTIES CONCERNING THE SELLER

     The Seller hereby represents and warrants to the Purchaser as follows as of the date hereof and as of the Closing Date:

     Section 2.1 Power and Authority. The Seller has the power and authority to enter and deliver this Agreement, to perform his/her obligations hereunder and carry out the transactions contemplated by the Agreement.

     Section 2.2 Enforceability of the Agreement. The Agreement constitutes a legal, valid and binding obligation of the Seller, enforceable against the Seller, in accordance with its terms, except to the extent that enforceability may be limited by bankruptcy, insolvency or other similar laws affecting creditors’ rights generally.

     Section 2.3 No Conflict. The execution, delivery and performance by the Seller of the Agreement and the consummation by the Seller of the transactions contemplated hereby and thereby, and the sale and delivery by the Seller of the Securities will not (a) violate any provision of law, statute, rule or regulation (including stock exchange rules), or any ruling, writ, injunction, order, judgment or decree of any court, administrative agency or other governmental body applicable to the Seller or any of its properties or assets, or (b) conflict with or result in any breach of any of the terms, conditions or provisions of, or constitute (with due notice or lapse of time, or both) a default (or give rise to any right of termination, cancellation or acceleration) under any agreement of the Seller, or result in the creation of any mortgage, lien, security interest, loan, charge or encumbrance, upon any of the properties or assets of the Seller.

     Section 2.4 Consents. No permit, authorization, consent or approval of or by, or any notification of or filing of the Seller with any person (governmental or private) is required in connection with the execution and delivery by the Seller of the Agreement or any documentation relating thereto, the consummation by the Seller of the transactions contemplated hereby or thereby, or the sale or delivery of the Securities.

     Section 2.5 Title to Shares. Upon delivery of the Securities as provided in Section 1.4, the Securities will be duly authorized and validly issued, and the Purchaser will acquire good and valid title to the Securities, free and clear of any encumbrances and liens. The Securities shall be fully paid and non-assessable.

     Section 2.6 Stock. The Seller is acquiring the Stock for his/her own account, for investment and not with a view to the distribution thereof within the meaning of the Securities Act and the Seller has no contract, understanding, agreement or arrangement with any person to transfer to such person or any other person any of the Stock, and the Seller has no present intention to enter into any such contract, understanding, agreement or arrangement. The Seller understands that (i) the Stock has not been registered under the Securities Act or any state securities laws, (ii) the Stock may not be sold unless such disposition is registered under the Securities Act and applicable state securities law or is exempt from registration and/or regulation thereunder as the case may be and (iii) that the availability of the exemptions relied upon by Penske in issuing the Stock is dependent, in part, upon the truth of the representations and warranties made by the Seller in this Agreement. The Seller is an “Accredited Investor” (as defined in Rule 501(a) under the Securities Act).

     The Seller (1) is thoroughly familiar with the business of Penske, (2) is knowledgeable and experienced with respect to the financial, tax and business aspects relating to the ownership of the Stock, (3) is familiar with the risks associated with the business and operations of Penske, (4) has made all investigations that the Seller deems necessary or desirable in connection with its investment, (5) has had an opportunity to discuss Penske’s business, management, and financial projections with representatives of Penske and to ask questions of and receive answers regarding the terms and conditions of the transactions contemplated hereby, (6) has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of its investment in Penske, and (7) has the ability to bear the economic risks of its investment in Penske for an indefinite period of time, including the risk of a complete loss of its investment.

     The Seller understands that that the shares of Stock are “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to these laws, the Seller must hold the shares of Stock indefinitely unless they are registered with the Securities and Exchange Commission and qualified by the state authorities (unless an exemption from such registration and qualification requirements is available) and Penske is under no obligation (and has no intention) to register the Stock under any circumstances or to attempt to make available any exemption from registration under the Act or any applicable state securities law, at the Seller’s expense or otherwise.

     The Seller acknowledges that (1) if an exemption from registration or qualification is available, it may be conditioned on various requirements, including but not limited to the availability of current public information about Penske, the time and manner of the sale, and on requirements relating to Penske that are outside of the Seller’s control; and (2) Penske is not presently subject, and may never be subject, to the reporting requirements of the Securities Exchange Act of 1934, as amended, to the extent required to enable the Seller to sell its shares of Stock pursuant to Rule 144 under the Act.

     The Seller understands that no public market now exists for any of the securities issued by Penske, and that Penske has made no assurances that a public market will ever exist for the Stock.

     The Seller is relying solely on its own conclusions or the advice of its own counsel or advisors with respect to the tax aspects of its investment in Penske.
