Are you serious?!? You really don't know the difference between title jumping and selling without a title? I'm afraid I can't help you, then!! I don't know how to explain it anymore simply than I already have.
Maybe try this...
Title jumping is buying a vehicle with a title, not registering it in your name and then selling to the next guy. He gets the title with the info from the guy you bought from. It doesn't have your info on it. Thus the term "jumping". It's really quite simple to understand, at least I thought it was!!
Selling without a title is... well... do I really have to explain the difference?!?
Are you for real?!?
