EXHIBIT 24

LIMITED POWER OF ATTORNEY FOR
SECTION 16 REPORTING OBLIGATIONS

      KNOW ALL BY THESE PRESENTS, that the undersigned, Gillian
A. Hobson (the "Reporting Person"), hereby constitutes and
appoints Brandon Brunet and Ann Cowper as the Reporting Person's
true and lawful attorneys-in-fact (each an "Attorney-in-Fact"
and, collectively, the "Attorneys-in-Fact"), each, individually
or jointly, to have full power to act in my name, place and
stead and on my behalf to do and execute all or any of the
following acts, deeds and things:

      (1)	prepare, execute in the Reporting Person's name and on
the Reporting Person's behalf, and submit to the United States
Securities and Exchange Commission (the "SEC") a Form ID,
including amendments thereto, and any other documents necessary
or appropriate to obtain codes, passwords, and passphrases
enabling the Reporting Person to make electronic filings with
the SEC of reports required by Section 16(a) of the Securities
Exchange Act of 1934 or any rule or regulation of the SEC;

      (2)	execute for and on behalf of the Reporting Person in
the Reporting Person's capacity as an officer or director of
Group 1 Automotive, Inc. (the "Company"), Forms 3, 4 and 5 in
accordance with Section 16(a) of the Securities Exchange Act of
1934, as amended (the "Exchange Act"), and the rules thereunder;

      (3)	do and perform any and all acts for and on behalf of
the Reporting Person which may be necessary or desirable to
complete and execute any such Form 3, 4 or 5 and timely file
such form with the SEC and any stock exchange or similar
authority; and

      (4)	take any other action of any type whatsoever in
connection with the foregoing which, in the opinion of such
attorney-in-fact, may be of benefit to, and in the best interest
of, or legally required by, the Reporting Person.

	The Reporting Person hereby grants to each such attorney-
in-fact full power and authority to do and perform any and every
act and thing whatsoever requisite, necessary or proper to be
done in the exercise of any of the rights and powers herein
granted, as fully to all intents and purposes as the Reporting
Person might or could do if personally present, with full power
of Substitution or revocation, hereby ratifying and confirming
all that such attorney-in-fact, or such attorney-in-fact's
substitute or substitutes, shall lawfully do or cause to be done
by the virtue of this power of attorney and the rights and
powers herein granted. The Reporting Person acknowledges that
the foregoing attorneys-in-fact, in serving in such capacity at
the request of the Reporting Person, are not assuming, nor is
the Company assuming, any of the Reporting Person's
responsibilities to comply with Section 16 of the Exchange Act.

	This Power of Attorney supersedes any power of attorney
previously executed by the Reporting Person and shall remain in
full force and effect until the Reporting Person is no longer
required to file Forms 3, 4 and 5 with respect to the Reporting
Person's holdings of, and transactions in, securities issued by
the Company, unless earlier revoked by the Reporting Person in a
signed writing delivered to the foregoing attorney-in-fact.

	IN WITNESS WHEREOF, the Reporting Person has caused this
Limited Power of Attorney to be executed this 28th day of
December 2023.
