Vatch touched on it.
Fact is, you do not need a tittle to own any vehicle. You might wish to have a bill of sale, to withstand challenges to ownership. However, if you want to operate it on government roads, it must be legally registered. And, you can't register it in your name without proof of ownership. Then the government will grant you the priviledge of highway use, as long as you contribute to the maintenance of the roads, and the beauracracy to support them.
