If you have a cosigner with perfect credit and a long history then it doesn't really matter what your score is (or how many times you have been declined credit before). They will give you the car because they know someone with sky high credit like that is not gonna let their credit rating go down the drain by you missing payments and will make your payments if need be to protect that perfect credit rating.

Before getting a co signer you should read the forum on relationships and money. Are you willing to lose your relationship with that person if you get in a pinch one month?
