Look, you are already in a rebuild status due to the BK. IF there were an impact due to the lender's report of a repo on a credit report, it would still pale in comparison to the impact of the BK.
I hope you found this response to be of assistance. This response shall not be considered the rendering of legal advise but instead a general response to a general question. While Avvo is a wonderful resource, nothing can be a substitute for an in-depth consultation with an attorney in the jurisdiction in which the law is to be applied. This response shall not be deemed to create an attorney-client relationship, nor shall it create an obligation on the part of the attorney to respond to further inquiry from the questioner.
From the facts that you stated, you should not be responsible for the loan on the car you currently own. Before you move forward, I think you should ask your lawyer to be sure you are doing everything correctly. He/she knows the facts better than anyone. I would also be cautious about taking on new debt. Any debts you take on you will be responsible for and will not be able to file another bankruptcy for years.
