Edmunds True Market Value (TMV), also known as Edmunds Suggested Price, is a pricing system that helps you determine the average transaction price — or what others are paying — for new or used vehicles in your area so that you can begin your negotiations with a fair price in mind. For customers appraising their vehicles for sale, Edmunds TMV helps you understand how much you might expect to receive when you sell.
We determine those prices based on a variety of factors, including actual transaction data from dealers. CarMax is one of the dealers from which Edmunds obtains transaction data.
Edmunds has been a wholly owned subsidiary of CarMax, Inc. since June 2021. However, other than the incorporation of CarMax's transaction data by Edmunds into TMV calculations, CarMax does not participate in or otherwise influence the manner in which Edmunds computes those values. Learn more
