Gsforless you did the right thing by junking the car,I had the same thing done to me on a truck in my own state,I called the guy numerous times and told him I was going to junk the title,as I soon did,I had seen the truck and it had different state plates on it,so I guess he got a title in another state,Pretty much what a tard,he could have just transferred it and not had any problems.If a bill of sale is okay to have as proof,Then somebody let me use there car to rob a bank and see who's house they come to,NOT MINE!
