We have performed the procedures enumerated below, which were agreed to by the Board of Directors and Management of Credit Acceptance Corporation and Wells Fargo Securities, LLC(collectively, the “specified parties”), in their evaluation of certain information with respect to attributes of the electronic file of information for the population of vehicle loans to be pooled for securitization related to the Class A, Class B, and Class C Asset-Backed Notes to be issued by the Credit Acceptance Auto Loan Trust 2020-1. The sufficiency of these procedures is solely the responsibility of the parties specified in this report. Consequently, we make no representation regarding the sufficiency of the procedures enumerated below either for the purpose for which this report has been requested or for any other purpose.

The procedures we performed and our findings are as follows.

1. The Company provided an electronic file (the “Data File”) with information for certain vehicle loans which the Company represented was as of the close of business of December 31, 2019.

2. Grant Thornton selected one hundred vehicle loans on a random basis from the Data File. The sample of loans are listed in Exhibit A. For each of the selected loans we compared the following information, designated by Wells Fargo Securities, LLC, to the related retail installment contract and in instances where consumers changed their address subsequent to the origination of their loan, we agreed the state of the consumer to other Company records.

a. Loan number

b. Original amount financed

c. First payment date (scheduled)

d. Original term to maturity

e. Monthly payment

f. Interest rate

g. State

h. Compared the Vehicle Identification Number (“VIN”) on the contract to the VIN on the title document (actual title, title application or VINtek, as applicable)

GT.COM Grant Thornton LLP is the U.S. member firm of Grant Thornton International Ltd (GTIL). GTIL and each of its member firms are separate legal entities and are not a worldwide partnership.

We defined the term “compare” as meaning we compared to the information shown in the Data File and found it to be in agreement. Such information was deemed to be in agreement if differences were attributable to rounding. The term “rounding” was defined as meaning amounts and percentages that were within $1 and 0.1%, respectively. We noted no exceptions.

This agreed-upon procedures engagement was conducted in accordance with attestation standards established by the American Institute of Certified Public Accountants. We were not engaged to and did not conduct an examination or review, the objective of which would be the expression of an opinion or conclusion, respectively, on certain information with respect to attributes of the electronic file of information for the population of vehicle loans to be pooled for securitization related to the Class A, Class B, and Class C Asset-Backed Notes to be issued by the Credit Acceptance Auto Loan Trust 2020-1. Accordingly, we do not express such an opinion or conclusion. Had we performed additional procedures, other matters might have come to our attention that would have been reported to you.

Our agreed-upon procedures engagement was not conducted for the purpose of the following:

• Addressing the conformity of the origination of the assets to stated underwriting or credit extension guidelines, standards, criteria, or other requirements

• Addressing the value of collateral securing any such assets being securitized

• Addressing the compliance of the originator of the assets with federal, state, and local laws and regulations

• Satisfying any criteria for due diligence published by a nationally recognized statistical rating organization

• Addressing any other factor or characteristic of the assets that would be material to the likelihood that the issuer of the asset-backed security will pay interest and principal in accordance with applicable terms and conditions

• Forming any conclusion

• Any other terms or requirements of the transaction that do not appear in this report.

This report is intended solely for the information and use of the specified parties. It is not intended to be, and should not be, used by anyone other than these specified parties, including investors and rating agencies, who are not identified as specified parties but who may have access to this report as required by law or regulation.
