Your Social Security benefits cannot be garnished. Your automobile would have to be worth money (i.e. be nearly new or have a high blue book value) in order for it to be valuable for the bank to take. If you are living on fixed income and you are past the age of being gainfully employed, it is probably not worth it for the creditor to pursue you. It can, of course, sue you in court and get a judgment. But it would have difficulty collecting on that judgment. The creditor may decide that it is not worth the time and effort.
