What can happen if I never gave my atv over for repossession?

My friend purchased two atv’s in his name, under his credit because mine was non existent at the time. I would pay him in cash for my atv, and then he would in turn take that and make the official payments to the creditor. It turned out that he wasn’t making any payments and was pocketing my cash payments. The creditor ordered a repo of both atv’s, and my friend’s was successfully taken back, however, mine never was. This happened in 2010. I still have the atv in my possession. Can I get in trouble legally for having it in my possession, and can it be taken from me?
