            This Amendment No. 6 (this "Amendment") amends the Statement on
Schedule 13D originally filed on January 22, 2008 (the "Original Schedule") by
the Reporting Persons, which Original Schedule was subsequently amended (the
Original Schedule as amended by Amendments No. 1 through 6, is referred to as
the "Schedule 13D") by the Reporting Persons and is filed by and on behalf of
the Reporting Persons with respect to the common stock, $0.01 par value per
share (the "Common Stock"), of AmeriCredit Corp., a Texas corporation (the
"Company"). Unless otherwise indicated, all capitalized terms used herein have
the meaning ascribed to them in the Schedule 13D.

ITEM 4.     PURPOSE OF TRANSACTION.

Item 4 of the Schedule 13D is hereby supplemented, with effect from the date of
this Amendment, by adding the following:

            On March 4, 2008, Leucadia and the Company entered into a standstill
agreement, which is described in Item 6 of this Amendment and incorporated
herein by reference.

            On March 4, 2008, the Company announced that two Leucadia designees
were elected to the Company's Board of Directors (the "Board"), as further
described in Item 6 of this Amendment and incorporated herein by reference.

ITEM 6.     CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH
            RESPECT TO SECURITIES OF THE ISSUER.

Item 6 of the Schedule 13D is hereby supplemented, with effect from the date of
this Amendment, by adding the following:

            On March 4, 2008, Leucadia and the Company entered into a two year
standstill agreement (the "Standstill Agreement") providing for, among other
matters, a cap of 29.9% ownership for the Reporting Persons (subject to certain
provisions), representation for Leucadia on the Board (with Leucadia having the
right to designate two of the Company's nine directors and the Company agreeing
not to increase the size of the Board above nine directorships without the
consent of both Leucadia's designees to the Board and a majority of the Board
unaffiliated with Leucadia), Leucadia's agreement to vote for the Board's
director nominees, certain restrictions on proposals that may be made by the
Reporting Persons (including as to the composition of the Board) without
approval of the Board, and the Company's agreement to enter into a registration
rights agreement covering all shares of the Company's common stock owned by
Leucadia, all on the terms and conditions set forth in the Standstill Agreement.
The restrictions under the Standstill Agreement will terminate early if the
Reporting Persons own less than 5% of the Common Stock. The Standstill Agreement
is attached hereto as Exhibit 1 and is incorporated in its entirety herein by
reference.

            Pursuant to the Standstill Agreement, on March 4, 2008, the Company
filed a Current Report on Form 8-K with the Securities and Exchange Commission
announcing, among other things, that the Board had created two new director
positions and elected Ian M. Cumming, Leucadia's Chairman, and Justin R.
Wheeler, a Vice President of Leucadia, to fill those positions.


ITEM 7.     MATERIAL TO BE FILED AS EXHIBITS.

EXHIBIT 1         Standstill Agreement, dated March 4, 2008, between Leucadia
                  National Corporation and AmeriCredit Corp.
