Its getting harder and harder to drive on the street these days without getting hassled by cops, but they can't hassle you if you trailer it to and from events and if you have a problem out there you just need to load the car back on the trailer and don't have to worry how you are going to get home.
But if someone absolutely had to have something to drive on the street and wanted this, you could buy a cheap cressida shell and swap everything over.
