re: Where can a young person get a car loan with poor credit in BR?

I'd at least try a local credit union first.
I've always gotten the best auto rates from CU's, albeit with good credit.
Being that credit unions are member owned (and focused on members needs), you might be surprised by their flexibility.
The worst that could happen is a denial.
If approved by a CU, I'd expect this is where she would get the best rate.
