The Fair Market Range is Kelley Blue Book’s estimate of what a consumer can reasonably expect to pay this week in their area for a particular year, make and model vehicle configured with their selected options, excluding taxes, title and fees and any rebates and incentives, when buying from a dealer. The Fair Market Range for Used Cars also considers the car’s mileage. Prices in the Fair Market Range are determined from our process of collecting hundreds of thousands of vehicle transactions each week and updating our pricing with that information. The Kelley Blue Book Price Advisor displays a Fair Market Range where the majority of vehicle transactions happen for that particular configuration.
