I am sory to hear about the lates.
Sadly I think you will have trouble getting a prime auto loan.
I am sure sub prime lenders will approve you.
Try things like Capital One Auto Navigator to see if you are pre-approved.
Forgot to add:
Don't rule out a CPO. I stand by that even if there were no score/financial limitations on you. Maybe you really like the S6 but have the budget for an A6 but CPO an S6 might be the same price as a new A6....
