Don't forget that the KBB has 3 values: retail, private party, and trade-in/wholesale. I think everyone here is talking about the private party value. However this is probably based on the retail and trade-in values which are dealer-based. At least here in Nevada, the DMV doesn't care about what you paid for a private party car so I don't see how KBB could get a hold of the selling prices on the private market.
