I’m a mechanic. I worked on a car around 7/8 years ago and the owner refused to pay me for it so it’s just been sitting in my garage collecting dust. The first year I tried to come up with a payment plan for the client. He agreed to pay me then he sent guys to intimidate me into giving it to him for free so I ceased communication with him. He hasn’t tried to reach out or claim the car since. I would like to get rid of it. What should I do?
