Put it up for sale, if you think you can get the price. Otherwise, if you really need to not have the car, have the dealer see if he can roll the difference into a new loan, or see of the bank will give you a personal loan for the difference. Or, do like me, and keep the other car. You can use Dodge's payment estimater to figure out what you can afford. Figure 6-8% interest if you have good credit, 8-10% if you have ok credit. Talk to the dealer about rolling the difference into a new loan or call your bank about a personal loan. The personal loan will probably save you more money in the end.
