Private Party Value (Private Party Value is what a buyer can expect to pay when buying a used car from a private party.)
Suggested Retail Value (The Kelley Blue Book Suggested Retail Value is representative of dealers' asking prices and is the starting point for negotiation between a consumer and a dealer.)
