“You’re in a rough predicament, and there’s no straightforward way to get out of this loan.
You probably won’t be able to refinance the loan, and, even if you can, chances are your interest rate won’t go down.
Your best bet is to put as much money as you can toward the principal each month. Although you’re playing catch-up, you’ll eventually break-even between the loan balance and the value of the car (hopefully!).
From there, you can continue to make payments until the vehicle is paid off, or you can sell your car and get rid of the loan altogether.”
