in many places you can register a vehicle like that as a "kit car" or "self-built" so long as you don't buy it as a complete car. you get a rolling chassis and it's up to you to put in the powertrain. 's how people get to drive cars like the Ariel Atom on the road.If those trucks were street legal I would have had one by now. I did see one on the street in Grand Rapids once but don't know how they got away with it.
