I actually thought about filing for a lost title and then repossesing it. I actually really miss that truck. lol
I like the idea of telling him you are gonna report it stolen... but wouldn't your mother still have to pay the fines? (If he just ignores you, and you get it back) I'm not too sure about the laws where you are but it sounds right to me.
Also, would it be legal for you to repo it? :/
