This Amendment No. 29 (this “Amendment”) amends and supplements the amended Schedule 13D filed on behalf of Penske Corporation, a Delaware corporation, and Roger S. Penske with the Securities and Exchange Commission on September 8, 2016 (the “Schedule 13D”), relating to the voting common stock, par value $0.0001 per share (the “Voting Common Stock”), of Penske Automotive Group, Inc., a Delaware corporation (the “Company”).  Penske Corporation and Roger S. Penske are the current reporting persons under the Schedule 13D (the “Reporting Persons”). Information reported in the Schedule 13D remains in effect to the extent that is amended, restated or superseded by information contained in this Amendment or a prior amendment.  Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Schedule 13D.

This Amendment is being filed to reflect the following transaction:

·                  On October 20, 2017, Penske Corporation, through its wholly owned subsidiary, Penske Automotive Holdings Corp., as Purchaser, and Mitsui, as Sellers, entered into a Purchase Agreement, which provided for the sale of 1,103,996 shares of Voting Common Stock owned by Mitsui to Purchaser for a cash purchase price of $45.29 per share (the “Mitsui Purchase Agreement”), which is filed as an exhibit to this Amendment and is incorporated by reference herein.  Additionally, on October 20, 2017, Penske Corporation and Mitsui entered into a Letter Agreement, pursuant to which the parties amended certain provisions of the Stockholders Agreement to, among other things, increase the number of shares of Voting Common Stock exempt from the tag-along rights of Mitsui from 1,992,408 to 3,096,404.  All other provisions of the Stockholders Agreement remain in full force and effect.

Item 2.  Identity and Background.

Item 2 of the Schedule 13D is hereby amended and supplemented as follows:

Information with respect to the directors and executive officers of the Reporting Persons set forth in Annex A to the Schedule 13D is hereby amended and restated in its entirety as set forth in Annex A to this Amendment and is incorporated herein by reference.

Item 3.  Source and Amount of Funds or Other Consideration.

The total amount of funds used to purchase the 1,103,996 shares of Voting Common Stock acquired by Penske Corporation as described in Item 5 below was approximately $50,000,000.  Such funds were obtained from the working capital of Penske Corporation.

Item 4.  Purpose of Transaction.

Item 4 of the Schedule 13D is hereby amended and supplemented as follows:  The Voting Common Stock to be purchased by Penske Corporation pursuant to the Mitsui Purchase Agreement was purchased for investment purposes.  Upon the closing of the transaction, Penske Corporation and Mitsui entered into a Letter Agreement, pursuant to which the parties amended certain provisions of the Stockholders Agreement to, among other things, increase the number of shares of Common Stock exempt from the tag-along rights of Mitsui from 1,992,408 to 3,096,404.  All other provisions of the Stockholders Agreement remain in full force and effect. A copy of the Mitsui Purchase Agreement and the Letter Agreement are filed with this Amendment as Exhibits 20 and 21 and are incorporated herein by reference.

Item 5.  Interest in Securities of the Issuer.

Based on information provided by the Company, as of October 18, 2017, there were 85,768,120 shares of Voting Common Stock outstanding.  Based on this amount of shares of Voting Common Stock outstanding:

(a)         As of October 20, 2017:

4

·                  Penske Corporation beneficially owned 35,218,820 shares of Voting Common Stock, representing 41.1% of the Voting Common Stock outstanding.  These figures reflect the beneficial ownership of shares of Voting Common Stock by Roger S. Penske and Penske Corporation as a group.  The number of shares of Voting Common Stock beneficially owned by Penske Corporation without regard to such group status is 34,181,121 shares, representing 39.9% of the outstanding Voting Common Stock.  See Annex A for beneficial ownership information with respect to directors and executive officers of Penske Corporation.

·                  Roger S. Penske beneficially owned 35,218,820 shares of Voting Common Stock, representing 41.1% of the Voting Common Stock outstanding.

The parties to the Stockholders Agreement (as defined in Item 6 in Amendment 26 to the Schedule 13D) may be deemed to constitute a “group” within the meaning of Section 13(d) of the Exchange Act and, as a party to the Stockholders Agreement, as amended, each of Penske Corporation and Roger S. Penske may be deemed to share beneficial ownership of the shares of Voting Common Stock owned by Mitsui.  Penske Corporation and Roger S. Penske expressly disclaim beneficial ownership of any shares of Voting Common Stock held by Mitsui. In Amendment 8 to Schedule 13D filed on October 23, 2017 by Mitsui, Mitsui reported beneficial ownership of 14,455,221 shares of Voting Common Stock. Including the shares reported by Mitsui under its Schedule 13D, Penske Corporation and Roger S. Penske would beneficially own 49,674,041 shares of Voting Common Stock, representing 57.9% of the Voting Common Stock outstanding.

(b)         As of October 20, 2017:

Penske Corporation shared power to direct the vote of 34,181,121 shares of Voting Common Stock and shared power to direct the disposition of 34,181,121 shares of Voting Common Stock.  See Annex A for information with respect to directors and executive officers of Penske Corporation.

Roger S. Penske had the sole power to direct the vote of 583,338 shares of Voting Common Stock, shared power to direct the vote of 34,635,482 shares of Voting Common Stock, had the sole power to direct the disposition of 583,338 shares of Voting Common Stock and shared power to direct the disposition of 34,635,482 shares of Voting Common Stock.

Item 6.  Contracts, Arrangements, Undertakings or Relationships with Respect to Securities of the Issuer.

Credit Agreement

On May 11, 2016, Penske Corporation entered into a Credit Agreement for a $700 million credit facility maturing on May 11, 2021 (the “Credit Agreement”), replacing its existing $550 million credit facility. In connection with the Credit Agreement, Penske Corporation entered into a Guarantee and Collateral Agreement (the “Collateral Agreement”) pursuant to which Penske Corporation granted, for the benefit of the lenders under the Credit Agreement, a security interest in substantially all of Penske Corporation’s property, including 34,181,121 shares of Voting Common Stock beneficially owned by Penske Corporation (the “Pledged Stock”).

Under the Credit Agreement, subject to certain exceptions, Penske Corporation may not dispose of Pledged Stock, unless it obtains the consent of the required lenders under the Credit Agreement.

In the absence of an event of default under the Credit Agreement, Penske Corporation is entitled to receive all cash dividends paid by the Company in respect of the Pledged Stock in the normal course of business and exercise voting and corporate rights with respect to the Pledged Stock. If an event of default occurs and is continuing under the Credit Agreement, the administrative agent under the Credit Agreement (the “Administrative Agent”) will be entitled to (i) receive any cash dividends payable in respect of the Pledged Stock, (ii) exercise all voting and corporate and other rights with respect to the Pledged Stock and (iii) exercise all remedies under the New York Uniform Commercial Code granted to secured parties, including the sale of all or a portion of the Pledged Stock. Under the Credit Agreement, an event of default will occur only after any requirement for the giving of notice, the lapse of time, or both, shall have been satisfied.

5

If, upon an event of default, the Administrative Agent exercises its right to sell the Pledged Stock, and in so doing deems it advisable to have the Pledged Stock registered under the Securities Act of 1933, Penske Corporation must, to the extent permitted by law and to the extent Penske Corporation can contractually do so, cause the Company to register the Pledged Stock under the Securities Act of 1933.
