The Kelley Blue Book® Trade-in Value is Kelley Blue Book's estimate of what a consumer can expect to receive from a dealer for a trade-in vehicle assuming an accurate appraisal of condition. This value will likely be less than the Kelley Blue Book® Private Party Value because the reselling dealer incurs the cost of safety inspections, reconditioning and other costs of doing business.
