When you do sell the car - PULL THE PLATES.
Or notify your DMV immediately. Whatever your state allows to relieve you of liability.
I trusted a nice couple who bought a car of mine. I then got toll bills for over a year. After the first toll bill, I did send the state a notice of the sale. But the damage was done.
I never paid the toll bills of course. They ran up only $500 in unpaid bills. I got a call one time from a collection agency making veiled threats. I told them to go pick up the car. Never heard another word from then again.
Since the buyer never registered the car it was still legally mine. I thought about hunting it down and taking it back. But that would probably backfire on me.
Last time I sold a truck, I had to go to the next county to meet. Guy was in a ankle bracket because the court order.
Once I had his money he threatened me. Had to tell him I would kill him if he wanted to F around.
Now my old cars are driven till they die and used for yard art.🚙🚗🚐
