I don't trust KBB anymore as there estimates for selling to a Private party are always too close to the what the dealer trader in will be. When I sell a car on AutoTrader, I will see how much the same vehicle is advertised as used from dealers. People are willing to pay that price as they know real value of the car. KBB used to be more reliable, in my opinion, the car companies and KBB are working together. I just did KBB on my 2014 Sierra Denali with 2,000 miles on it, the estimate was $42K. give me a break. That reminds me, I need to get GM to buy this truck sooner than later.
