I have bad credit 510 but can put a 2000 BMW 328i down. Is it possible to get a car with payments under 300.

I dont know. Its hard to say. It depends on the bank that finances you plus the car u choose. U may have to get something used a new car would be hard to get payments under 300. My score was a 530 when i went, i put down 4000 down and my payments are 405 a month....2018 kia forte....i choose to go new though....up to u what u decide but u may need more$ down if u want that payment under 300

I think so should be especially if you have a trade in my credit is bad too and I had no money down nor trade in and my payments are a lil over 300

Probably not
