What are my changes of getting a 10k personal loan with bad credit, but have a co-signer?

I have pretty badcredit, probably around 550-570. I've been looking for a personal loan around 10k to get a car and pay some things off but have been denied. I can easily afford a monthly payment of $300 - 350. My co-signer has a house, has a stable job, etc. I know they had a bankruptcy but that has been over 7 years ago.
