They are trying to screw you.Now that you don't have the old car, they want to take away the new car, and you will be desperate for ANY CAR / ANY DEAL.Try to make then keep the first deal.===Now you know what dealers do. So next time separate 3 parts of the transaction(1) resell your car privately - don't trade it in(2) go to a bank / credit union and secure a loan(3) go buy a car Good Luck...
