Bad credit car loans without having to go through a dealership?

Up until the 13th, I had a 2006 Fusion that was unfortunately totaled in an accident due to snow. I was able to get that car because my mom took out the loan for me. But since she has two cars plus our house on her credit [my dad and her are joint owners of it]...her debt to income ratio pretty much froze her credit even though her score is really good, so she can't co-sign with me for anything. My dad pays cash for everything and has never had anything other than the house on his credit, so he can't be used as a co-signer either, because he has next to no credit. I have a car priced at about $8000 through a private seller picked out. Now I just need to find a loan. I've noticed there are a lot of dealerships out there that will finance people with bad credit, BUT you have to go through that dealership in order to get the financing. Are there any places that offer car loans to people with bad credit WITHOUT going through a dealer? Thanks in advance.
