Always, ALWAYS, get the "out the door" price. Ed and I have a used-car lot in Michigan, where all dealers are limited to a $195 "Doc Fee" by the State (of course, many can find other things to charge fees for). Not every state does this - we were shocked to recently learn of a car dealer who is charging a $395.00 Doc Fee plus a $995 "Dealer Fee" in Florida. Granted, these steep fees can let the dealer show competitive prices in their advertising, but when they are done adding fees, it can drastically affect the actual selling price.
