i've got a couple of questions about trade ins, and if i'm thinking right there's a couple of you who work for carmax, so i was was wondering if you could help me out. i've been wanting to trade my 99gt in for a 97+ gtp, but i still have approx 2 grand in payments left. would it be better to finish paying it off, or how would i go about with a trade in with still having payments left? would they just deduct the amount that i still owe from the trade in, or is it more complicated than that? thanks in advance for the help.
