Although I'm not admitted in your state, I can give you general advice. A bankruptcy can be filed at this point, but whether or not you can keep the vehicle is a question best answered by local counsel, and the kind of papers being served against you. If the car is still out there, the lawsuit may be seeking an order of replevin. A chapter 7 can usually provide a temporary roadblock, while a chapter 13 is more permanent, but I'm sure there are attorneys in your area giving free consultations. You should take advantage of them.
