To get approved for a car loan with bad credit you'll need to find a used car dealer that will do in house financing and looks past the fact that you have bad credit and will get you approved for an auto loan by putting at least $500.00 down in cash.
There are some used auto car dealers out there that will approve you with bad credit for a car loan with a low down payment.
It would depend on what used car dealers are around your area on which one would approve you for a used car loan with bad credit rating.
