Car financed at 24.90% — what can I do?
You could look into refinancing with a bank or credit union.  But to weed out options quickly, use a service like LendingTree, which can vet multiple options for you a whole lot more quickly than you could probably do yourself.  (I don't work for, or get any benefit from LendingTree.)  Whatever you do, try to do all the applying within a short span of time, as to not negatively affect your credit score (read here) by creating extraneous inquiries.   Then again, if your credit sucks, you might not qualify for a re-fi.  If you are turned down, make your payments on time for six months or so, and try again.
