Kelley Blue Book

For over 90 years, Kelley Blue Book has been The Trusted Resource for used car values, helping car owners understand what their used car is worth. The Kelley Blue Book Trade-In Value shows what a consumer can expect to receive for their car this week when trading it in at a dealer. The Kelley Blue Book Private Party Value reports on a fair price when selling the car to an individual instead of doing a dealer trade-in.
