Auto finance is what I do for a living and I used to work for Ford. Back then a 600 was considered a good score but now it's considered a sub-prime score.
So it will come down to the loan to value, if you get a new car with large rebates plus your down payment you should be financing well below invoice (if the dealer gives you a good deal) and that will go a long way towards getting you approved with Ford. They like equity deals.
It also will depend on what makes up your score. If it's based on 1 credit card with a $500.00 limit paid 15-times and a couple of student loans then no. But if it's based on having a good profile including several trade lines paid as agreed over at least 3-4 years then it's possible.
Possibly, but probably not. And with a 600, it definitely wouldn't be for one of those 0% deals if you were. Those are given to people with top scores, 720 and higher.
