S.L.
I haven't sold mine yet and it's not brand new, got it in 2009, but the dealer told me for a trade in they will pay it off plus maybe a little ( but I'd doubt it would be any really over ) and another dealer told me they would take it on a trade if the other dealer said they would ( they are a different make of car dealer ). I don't know if this works if you buy less, and my car is a car sought after right now so maybe why they are more willing to do that. It's worth talking with a dealer about at least. I wouldn't buy a used car that is not paid off first.
