I sold mine by listing on Facebook. Had my husband show the car, met in public place. Looked up price on Kelly Blue book sp? I have done this more than once.
Only time I had a problem was one person didn’t transfer out of my name and I started getting parking ticket violations. Had to go to court.
Now I remove the license plate and file with dmv that the car was sold. In the future I may make them meet at the county office to transfer title.
