 I don't know. I would do some due diligence and homework and maybe even talk to an attorney to figure out what the right way to go about this is. Because I feel like you guys are in a precarious situation, and I'm not in on all the details, and I am not a legal expert. But this sounds like a nightmare if you don't get out of this ASAP. Is he the kind of guy that will figure out that you want the car back so he'll crash it on purpose or do something to it to try to get back at you?
