The Instant Market Value (IMV) of a vehicle is CarGurus’ estimated fair retail price for a vehicle based on a detailed analysis of comparable current and previously sold car listings in your local market. Our analysis takes into account specific details including make, model, trim, year, mileage, options and vehicle history. CarGurus uses IMV to determine whether each listed car is a Great, Good, Fair or High priced deal. CarGurus strives to provide full transparency to your car shopping experience so you'll know whether you're getting a good deal.
