I used to handle bankruptcy as a paralegal but that was before the big change-over with bankruptcy.
Call the lawyer that did your original bankruptcy. It may be possible to retroactively put the car on the bankruptcy. You can also ask them, if not, what your best option would be. Sometimes, the debt will charge off faster if you do not pay it than if you do (crazy I know).
The lender will probably remove all trace of it from my credit if I do pay it off.
Be *very* cautious here. If it's already on yoru credit report, they cannot do this (legally). However, creditors can and do lie about things like this all of the time.
