Independent Accountants’ Report

on Applying Agreed-Upon Procedures

Ladies and Gentlemen:

We have performed the procedures described below, which were agreed to by Santander Consumer USA Inc. (the “Company”) and Citigroup Global Markets Inc. (the “Other Specified Party” and, together with the Company, the “Specified Parties”) related to their evaluation of certain information with respect to a portfolio of automobile receivables in connection with the proposed offering of Chrysler Capital Auto Receivables Trust 2016-B (the “Transaction”).

This agreed-upon procedures engagement was conducted in accordance with attestation standards established by the American Institute of Certified Public Accountants. The sufficiency of these procedures is solely the responsibility of the Specified Parties of this report. Consequently, we make no representations regarding the sufficiency of the procedures described below either for the purpose for which this report has been requested or for any other purpose.

Agreed-Upon Procedures

At the instruction of the Company, we accessed the “Company Website” (https://portal.santanderpartners.com) on October 3, 2016 and obtained a computer-generated automobile loan data file and related record layout as of September 30, 2016 with respect to 36,280 automobile receivables (the “Statistical Loan File”).

At the instruction of the Company, we randomly selected (i) 145 automobile receivables (the “Non-Commercial Sample Receivables”) from the Statistical Loan File that were not noted as “Chrysler Commercial” and (ii) 30 automobile receivables (the “Commercial Sample Receivables” and, together with the Non-Commercial Sample Receivables, the “Sample Receivables”) from the Statistical Loan File that were noted as “Chrysler Commercial” and performed certain comparisons and recomputations for each of the Sample Receivables relating to the automobile loan characteristics (the “Characteristics”) set forth on the Statistical Loan File and indicated below.

Characteristics

1.   Vehicle identification number (“VIN”) 2.   Origination date 3.   Original amount financed 4.   Original term to maturity 5.   Model type (new/used) 6.   Original monthly P&I payment 7.   Original annual percentage rate 8.   Current monthly P&I payment 9.   Current annual percentage rate 10. FICO score 11. Custom score

We compared Characteristics 1. through 7. to the corresponding information set forth on or derived from an Installment Sales Contract (the “Contract”).

We compared Characteristics 1. through 5., 8. and 9. to the Company’s loan servicing system (the “Servicing System”).

We compared Characteristics 10. and 11. to a query (the “FICO and Custom Score Query”), provided to us by the Company on October 5, 2016 from the Company’s credit system (the “Credit System”).

Further, we compared Characteristic 1. to the Title Certificate, Application for Title or Guarantee of Title, Notice of Lien, Lien Entry Form, Confirmation of Lien Perfection, Vehicle Ownership Registration Form, Electronic Verification of Title, Vehicles Dealer Temporary Permit, Dealer Rebuilder or Lessor’s Report of Sale or Lease, Department of Financing & Administration Direct Lien Filling, Application for Assignment for “E” Dealers, Lien Receipt, Notice of Security Interest, Lien and Title Information Title Report, Affidavit & Notification of Sale of Motor Vehicle or other related correspondence (collectively, the “Title Certificate”).

At your instruction, for purposes of such comparisons:

• with respect to Characteristic 2., differences of thirty days or less are noted to be “in agreement;”

• with respect to Characteristic 4., differences of one month or less are noted to be “in agreement;”

• with respect to Characteristic 5., for those Sample Receivables where the model type was not indicated on the Contract, we were instructed by the Company to perform our comparison to the model type set forth on or derived from the “Purchase Contract” or Title Certificate. Further, a model type of (i) “refinance,” as set forth on the Contract, is noted to be in agreement with “used,” as set forth on the Statistical Loan File and (ii) “demo,” as set forth on the Contract, is noted to be in agreement with “new,” as set forth on the Statistical Loan File;

• with respect to Characteristic 7., in those instances where we observed two original annual percentage rates on the Contract, we were instructed by representatives of the Company to compare the lower value original annual percentage rate to the original annual percentage rate set forth on the Statistical Loan File;

• with respect to Characteristic 10., a FICO score of “0” as indicated on the FICO and Custom Score Query is noted to be “in agreement” with a “blank” FICO score as indicated on the Statistical Loan File; and

• with respect to Characteristic 11., a custom score of “NULL” as indicated on the FICO and Custom Score Query is noted to be “in agreement” with a “blank” custom score as indicated on the Statistical Loan File.

In addition to the procedures described above, for each of the Sample Receivables, we looked for the existence of the following:

• a Title Certificate (as defined above);

• the security interest of the Company or “Chrysler Capital” (or an Originating Affiliate, as represented to us by the Company) is indicated on a Title Certificate;

• a Credit Application, a Credit Application Status Report (from the Servicing System) or an Application for Financing (collectively, the “Application”);

• a Credit Bureau Report (from the Credit System),;

• a Truth-in-Lending Disclosure Statement; and

• the Agreement to Provide Insurance, Gap Waiver Addendum or other related documentation denoting the borrower’s current insurance status (collectively, the “Agreement to Provide Insurance”) for those Sample Receivables with insurance verifications not system generated, as indicated by representatives of the Company.

The automobile receivable documents described above, including any information obtained from the indicated systems and the FICO and Custom Score Query, and any other related documents used in support of the Characteristics were provided to us by representatives of the Company and are collectively referred to hereinafter as the “Receivable Documents.” We were not requested to perform, and we did not perform, any procedures with respect to the preparation or verification of any of the information set forth on the Receivable Documents and we make no representations concerning the accuracy or completeness of any of the information contained therein. In certain instances, our comparisons and recomputations were performed using data imaged facsimiles or photocopies of the Receivable Documents. In addition, we make no representations as to whether the Receivable Documents are comprehensive or valid instruments or reflect the current prevailing terms with respect to the corresponding Sample Receivables.

Agreed-Upon Procedures’ Findings

The results of the foregoing procedures indicated that the Characteristics set forth on the Statistical Loan File were found to be in agreement with the above mentioned Receivable Documents.
