Black Book is a dealer-exclusive publication specializing in wholesale valuation of used cars and trucks. Black Book values used vehicles in categories such as "extra clean," "clean," "average" and "rough."
Black Book sends weekly data to dealers who subscribe to its service. Each week, Black Book collects auction data on used vehicles and provides valuation estimates to dealerships. This helps dealers assess a vehicle's trade-in value and how much the potential trade-in could sell for at auction. Dealers also use this information to decide if the trade-in vehicle is profitable.
Black Book is similar to Kelley Blue Book. Kelley Blue Book also collects auction data and publishes value guides. These guides are available to the public online. Kelley Blue Book is largely used by consumers to value their vehicle's worth as part of a private sale.
