If I had that situation, I'd pay cash. The voluntary repo along with the BK would mean that if approved, you'd have to put down a hefty down payment and pay very high interest. You'd pay thousands over the cost of the car in interest alone. What I would do in the meantime is focus on repair and within a year or so, your situation might change and credit improved where you would be in a much better position to finance. Also know that CreditKarma offers scores, but they aren't FICO scores. Definitely check your FICO scores from time to time to track progress.
