Need Help Asap With This Question!!

I bought a used certified Toyota camry this past friday. and everything went down so fast that I signed the papers and I think I made a big mistake and was taken for a ride. according to the dealer they gave us $6900 for the trade in plus 2k that we gave as down payment. Now checking the paperwork at home it shows that the car price was $21900. that is suppost to be the price for a 2004 toyota Camry LE 4cylinders. Now I checked kelly's blue book and it tells me that a car like that is worth tops 15k, so it seens that I actually got nothing for the trade in. Now is this legal? is there anything I can do about it? Does any one knows if there is a way to give this car back? I'm extremely mad at the salesman and dealership for this. Any help would be extremely appreciated.

This is why you must come to a price agreement first, then tell them you have a trade in. You got jipped.

If you have signed and driven off the lot ,the car is yours. I get at least 5 calls a week from people in the same situation, unfortunatley the contract is a binding contract, better luck next time.
