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

A. We randomly selected a sample of 125 Receivables from the Initial Data File (the “Sample Receivables”). A listing of the Sample Receivables was provided to the Company. 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 Initial Data File.

B. For each Sample Receivable, we compared or recomputed the specified attributes in the Data Files listed below (all attributes are per the Initial Data File unless otherwise stated) 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 Files to the Receivable File, utilizing the Instructions as applicable, constituted an exception. The Receivable File information is listed in the order of priority.

Attribute	Receivable File/Instructions
Obligor’s State	Retail Installment Contract. If the Obligor’s State does not agree, compare to a servicing system screen print documenting an address change after the inception of the Sample Receivable.
Original Principal Amount	Retail Installment Contract
Monthly Payment Amount	Retail Installment Contract

Attribute	Receivable File/Instructions
Original Term to Maturity	Retail Installment Contract. If the Original Term to Maturity does not agree, compare to a servicing system screen print documenting an extension was granted to the obligor and the Original Term to Maturity increased as a result.
Origination Date	Retail Installment Contract
First Payment Date	Retail Installment Contract. If the First Payment Date does not agree, compare to a servicing system screen print documenting a first payment due date change was granted after the inception of the Sample Receivable.
Contract Annual Percentage Rate	Retail Installment Contract
Vehicle Make	Retail Installment Contract
Vehicle Model	Retail Installment Contract
Vehicle Model Year	Retail Installment Contract
Vehicle Identification Number	Retail Installment Contract
New or Used	Retail Installment Contract
Lienholder	Title Document. Consider variations due to spelling, abbreviation or truncation of the full legal name to be acceptable, to the extent such variation refers to “CarMax.” For Sample Receivables #47, #66, and #78, there was no Title Document available. The Company informed us this was because the vehicle was returned to the Company, and therefore the vehicle titling process has been cancelled after the Cutoff Date. These were not considered exceptions. The Company further informed us that, because Sample Receivables #47, #66, and #78 were closed after the vehicle was returned, they would not be included as collateral in the offering of the Transaction. As such, no further procedures were performed.
Sales Price of Vehicle	Retail Installment Contract
Existence of a Co-Obligor (per Co-Obligor File)	Retail Installment Contract Consider there to be a co-obligor if the “CoApp_Flag” field in the Co-Obligor File is “1,” and consider there to be no co-obligor if the “CoApp_Flag” field in the Co-Obligor File is “0.”

Obligor Payment-to-Income Ratio

Recompute the Obligor Payment-to-Income Ratio by dividing the Monthly Payment Amount stated in the Retail Installment Contract by the sum of the Obligor’s monthly income, the co-obligor’s monthly income, and additional income (excluding temporary income with codes “UUI,” “UNI,” or “STD” for Sample Receivables with an application date between June 16, 2020, and December 8, 2020), as applicable, stated in the Credit Application, and round the result to the 4th decimal place.

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 not intended to satisfy any criteria for due diligence published by the nationally recognized statistical rating organizations (“NRSROs”).
