We make no representation regarding the validity, enforceability, or authenticity of the information in the Receivable File.

·	The term “Provided Information” means the Instructions, Vehicle Model Mapping, Acceptable Company Names, and Receivable File.

The procedures we were instructed by the Company to perform and the associated findings are as follows:

A.	We randomly selected a sample of 150 Receivables from the Data File (the “Sample Receivables”). A listing of the Sample Receivables is attached hereto as Exhibit A. For purposes of this procedure, the Company did not inform us of the basis they used to determine the number of Receivables we were instructed to randomly select from the Data File.

B.	For each Sample Receivable, we compared the specified attributes in the Data File listed below to or using the corresponding information included in the Receivable File, utilizing the Instructions, as applicable. The Specified Parties indicated that the absence of any of the information in the Receivable File or the inability to agree the specified attributes from the Data File to the Receivable File, utilizing the Instructions, as applicable, constituted an exception. The Receivable File documents are listed in the order of priority.

	Attribute	Receivable File / Instructions

	Obligor’s First Name and Last Name	Installment Sale Contract, Federal Truth in Lending Disclosure Statement, Credit Application

	Contract Date	Installment Sale Contract, Federal Truth in Lending Disclosure Statement

	Original Term	Installment Sale Contract, Federal Truth in Lending Disclosure Statement

	Original Amount Financed	Installment Sale Contract, Federal Truth in Lending Disclosure Statement

	Scheduled Monthly Payment Amount	Installment Sale Contract, Federal Truth in Lending Disclosure Statement, Retail Installment Sale Contract Simple Interest Finance Charge letter

	Attribute	Receivable File / Instructions

	Annual Percentage Rate (“APR”)	Installment Sale Contract, Federal Truth in Lending Disclosure Statement, Retail Installment Sale Contract Simple Interest Finance Charge letter

	Vehicle Type (New or Used)	Installment Sale Contract, Federal Truth in Lending Disclosure Statement. Consider an entry of “C” in the Data File to be a Used vehicle.

	Vehicle Make	Installment Sale Contract, Federal Truth in Lending Disclosure Statement, Vehicle Model Mapping

	Vehicle Model	Installment Sale Contract, Federal Truth in Lending Disclosure Statement, Vehicle Model Mapping, Insurance Document

We found such information to be in agreement except as listed in Exhibit B.

C.	For each Sample Receivable, we observed the presence of the following in the Receivable File:

	1.	Title Document. We were instructed by the Company to observe that one of the Acceptable Company Names appeared on the Title Document as the Lien Holder, Owner, Security Interest Holder, or Secured Party.

	2.	Proof of Insurance. The Company instructed us to consider an Insurance Document to be acceptable proof of insurance. The Company further instructed us that no insurance document was required for Sample Receivables with the characteristics listed below because its underwriting policy does not require proof of insurance for these receivable types:

	(i)	Stip Tier 1 (Type “ST01” on the Analysis 1 screen in the Company’s servicing system)

	(ii)	Stip Tier 2 (Type “ST02” on the Analysis 1 screen in the Company’s servicing system) or Stip Tier 3 (Type “ST03” on the Analysis 1 screen in the Company’s servicing system) for which:

	a.	the Loan Application Update screen in the Company's servicing system indicates that the signed contract was received prior to April 1, 2024, or

	b.	the Credit Report Inquiry screen in the Company’s servicing system indicates the customer had an open automobile or mortgage loan and the Program in the Data File was “Pref.”

As such, the absence of an insurance document for Sample Receivables with these receivable types should not be considered an exception.

Signed Credit Application (not applicable to direct loans). We make no representation regarding the authenticity of the obligor’s signature(s).

We found such information to be present as required.

We were engaged by the Company to perform this agreed-upon procedures engagement and conducted our engagement in accordance with attestation standards established by the American Institute of Certified Public Accountants, which involves us performing the specific procedures agreed to and acknowledged above and reporting on findings based on performing those procedures. 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 the specified attributes in the Data File. 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.

We are required to be independent of the Company and to meet our other ethical responsibilities, in accordance with the relevant ethical requirements related to our agreed-upon procedures engagement.

The procedures performed were applied based on the information included in the Data File and Provided Information, without verification or evaluation of such information by us; therefore, we express no opinion or any other form of assurance regarding (i) the reasonableness of the information provided to us by the Company, (ii) the physical existence of the Receivables, (iii) the reliability or accuracy of the Provided Information which was used in our procedures, or (iv) matters of legal interpretation.

The procedures performed were not intended to address, nor did they address: (i) the conformity of the origination of the Receivables to stated underwriting or credit extension guidelines, standards, criteria or other requirements, (ii) the value of collateral securing any such Receivables being securitized, (iii) the compliance of the originator of the Receivables with federal, state, and local laws and regulations, or (iv) any other factor or characteristic of the Receivables 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. The procedures performed were not intended to satisfy any criteria for due diligence published by the nationally recognized statistical rating organizations (“NRSROs”).

The terms of our engagement are such that we have no responsibility to update this report because of events and circumstances that may subsequently occur.

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 any other person or entity, including investors or the NRSROs, who are not identified in the report as the Specified Parties but may have access to this report as required by law or regulation.
