SUBSTITUTE INFORMATION INCLUDED IN ACCORDANCE WITH GENERAL INSTRUCTION J
TO FORM 10-K:

ITEM 1112(b) OF REGULATION AB. (SIGNIFICANT OBLIGORS OF POOL ASSETS)

There is no single obligor that represents more than 10% of the pool assets.



---

ITEM 1114(b)(2) OF REGULATION AB. (CREDIT ENHANCEMENT AND OTHER SUPPORT, EXCEPT FOR CERTAIN DERIVATIVES
INSTRUMENTS (FINANCIAL INFORMATION))

There is no external credit enhancement or other support provider that is liable to provide payments supporting
any notes or certificates issued by the Issuing Entity.

ITEM 1115(b) OF REGULATION AB. (CERTAIN DERIVATIVE INFORMATION (FINANCIAL INFORMATION))

No entity provides any derivative instruments that are used to alter the payment characteristics of the cash flows from the Issuing Entity.

ITEM 1117 OF REGULATION AB. (LEGAL PROCEEDINGS)

No
legal proceedings are pending against the Sponsor, Depositor, Trustee, Issuing Entity, or any Servicer that would be material to the security holders of the Notes or Certificates.

ITEM 1119 OF REGULATION AB. (AFFILIATIONS AND CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS)

AmeriCredit Financial Services Inc., the Sponsor and the servicer, is a Delaware corporation and is the originator of 100% of the automobile loan contracts.
The Sponsor purchases automobile loan contracts that are originated and assigned to it by automobile dealers and, to a lesser extent, third-party lenders and also originates automobile loan contracts directly with consumers, either directly or
through a wholly owned subsidiary. The Sponsor services all automobile loan contracts that it purchases or originates on behalf of the Issuing Entity, AmeriCredit Automobile Receivables Trust 2013-1, a Delaware statutory trust.

The Sponsor sold and assigned the pool of initial automobile loan contracts to AFS SenSub Corp., the Depositor, a Nevada corporation. The Depositor then sold
the pool of sub-prime automobile loan contracts to the Issuing Entity and is the sole-owner of the certificate of the Issuing Entity.

General Motors Financial of Canada, Ltd., or GMF of Canada, is a wholly owned subsidiary of the Sponsor. GMF of Canada services a
portion of the automobile loan contracts in the United States on behalf of the Issuing Entity through its service center in Peterborough, Ontario. GMF of Canada utilizes the Sponsors standardized servicing policies and procedures and operates
on the same single, unified and interconnected software platform that the Sponsors other servicing centers utilize. GMF of Canada is managed by the same executive officers of the Sponsor that oversee the rest of the Sponsors operations,
including servicing through its other servicing centers. GMF of Canada is operated as a separate legal entity from the Sponsor due solely to the location of its servicing center in a foreign jurisdiction, despite being operated identically to the
Sponsors other servicing centers and not as a stand-alone entity (other than as is required for regulatory and corporate governance purposes).
