When I bought mine, I had a decent down payment, and I went through one of the "exotic car financing" places on eBay (where I bought the car). They approved me but the rate was horrendous.
I called my credit union, and they gave me a personal loan (unsecured) in the same amount, which a much lower interest rate!
The loan will be paid off in a few months. I'm looking forward to that, for sure!
