Automotive titles are interesting things and vary from state to state. Having moved from state to state over 30 plus years with Uncle Sam, I have had to opportunity to become "wise to the world of titles". Some states are money grubbers and insist upon you transferring the title to their state before attaining your registration, while others do not. I have raised objections to the transfer and some have said ok while others have said, "No transfer, No registration". I have used the argument that the Title is like a Deed and it goes with the land and is transfered with the land upon sale. Regardless, a seller that I deal with must provide proof of ownership before I become a buyer.
I was just a kid when Tenn went to vehicle titles and owners had to take their bills of sale to the new title offices to get their titles. This happened back in the 50s and my 36 coupe that I purchased from the original owner had a title with it in 1960. It has been registered in Tenn, Tx (twice), Ok (twice), South Carolina, and North Carolina. I wanted to keep the original Tenn Title, but they would not let me. It had to be turned in with the application for the new title to be issued to me.
