Dear Liz: My car payment is $465 a month with a 22% interest rate. I need to get out of this car and into a lower car payment. My credit is poor. What is the best solution to go about this?

Answer: There are a number of solutions, most of which probably won’t work for you.

If you could do without a car for a while and owe less than this car is worth, you could sell it to pay off the loan. The fact you haven’t already done so indicates that you either need a car or have no equity, or both.

Fixing your credit could help you get a better deal, but that’s tough to do with an unaffordable car payment. You need to have enough free cash flow to put a down payment on a secured credit card or make monthly payments on a credit builder loan, which are two of the best ways to rehabilitate your credit. Your finances also have to be sound enough that you don’t miss payments on any credit obligation, including the car.

If you bought an overpriced jalopy from a “buy here, pay here lot,” or you were approved at a regular dealership but your rate got jacked up at the last minute, the dealer may have violated Truth in Lending laws that would allow you to get out of the deal. You’d probably need an attorney to help you pursue this option. You may luck out and find one that can help you at your local legal aid society. Otherwise, you could check with the National Assn. of Consumer Advocates to see if you can find affordable help.

Even if you were successful in getting out of this loan, of course, you still are likely to need a car and you’d still have bad credit, which means that you probably wouldn’t get a better deal on the next car than the bad one you have now.

If you can, the best option might be to get a second job or ask for overtime hours to pay this loan off as fast as possible. Then you could get a credit builder loan, which puts the money you borrow into a certificate of deposit you can claim after making 12 monthly payments. This small loan could be enough to significantly boost your credit scores and give you some cash to make a down payment on the next vehicle.
