How can I get financed!?

[elizabeth]

I'm 18 years old and recently my car was totaled when someone rear-ended me. I found a new (well, new to me) car that I liked that was a good price. My dad then even negotiated it down to $11,900. I have $6,000 to put now but need to finance the other half.

Because I do not have a credit history, my mom and I were going to co-sign on the loan. However, my mom has poor credit (about 575) and we were declined. My dad will not co-sign with me and I do not want him to anyway as I have had problems with him being dishonest in our financial agreements in the past.

The car dealership said the only other option they could think of is to have us put only $5,000 down and get a loan with a 25% interest rate!

Any advice or other suggestions?! I'm so desperate and inexperienced with this sort of thing.
