Trade in

You will lose a lot of money that way. You probably owe more than you can sell it for.

Even if it's a lower price then the one I got?

What you owe on the car is a different issue than what other cars cost.

Dealers do not "swap" cars like trading cards. You sell one and then buy another. The term "trade in" is somewhat misleading apparently.

Trade in value is much lower than purchase price; especially if your using a new car dealer. Stay you paid $16.000 for the car; trade in might get you $13,000 in an ordinary deal. But if you trade the car to the same dealer and your purchase wasn't that long ago, he might give you a break because he knows the car and give you $14,000 contingent on your buying another car from him. Yes, you will take a loss on this exchange, but it might not be that bad, and it might make the trade worthwhile.
