Can I get a car loan with bad credit, But a large down payment?

I'm under 18 and Ive saved up a lot of money for my age in the past 6 months, 15,000. I will be using my moms credit and I will just give her the money for the payment each month. Now my moms cedit is bad...Recently went through a divorce and it basically just destroyed it. It's okay credit, but its still on the bad side. So the car I want is 32,000 USD, Please don't post answers saying you can buy a Kia or Honda out right. So even with his poor credit score, can I get a loan?
