You are screwed.
In general, when you drive off the lot, you lose 1/3 of the value of your car. You could likely get $38 in a trade. Why is this? It's no longer a new car. Why would someone want your used car for what they could get a new one? Heck....it could be a fully loaded $60k car and it's still not worth what a new $48k car is because.....well....it's used. Cars are not gold coins. They lose value when you buy them, lose more value when you drive them and when you trade, the dealers will want more profit one way or another.
