When a motor vehicle is repossessed there is still an opportunity to preserve your ownership.  If prior to the scheduled auction you have the financial means to remit a lump-sum payment in satisfaction of the past amount due, plus any late fees assessed, that may cure the issue.  However, some finance companies may also require that you include a deposit with that payment.  In addition, the cost of the repossession, the towing and impoundment expense, will then be added to the principal balance due on your loan.

Should that be beyond your capabilities, then you could alternatively file a Chapter 13 Bankruptcy. Doing so would prevent the sale, and require that the vehicle be returned to your care.  In addition, the finance company would then be required to accept a Court-controlled monthly payment to help you bring the obligation current over a multitude of years.
