Dealer asking price vs. trade-in vs. private sale
The prices on this page are what US dealers are asking for a GMC Sierra 1500 AT4 today, before negotiation, taxes and fees. A dealer's trade-in offer for the same car is usually well below its asking price, because the dealer has to recondition it, carry it and still make a margin.
