Wow, VERY strange (and very cool!). Looks like someone took a Vanagon and did some serious cosmetic work on it. Very nice ....
The shorty van I saw had the center door chopped out of the middle (along with everything else), and had the front and rear welded back together. The whole thing was about the same size as one of those SmartCars, maybe a shade longer but not by much - definitely smaller than a standard VW Bug. (One of the mechanics around my area has one in his shop yard, I'll see if I can get a picture of it.) Someone else did the same conversion with one of the "pickup" Volkswagons, made it into a shorty with a fifth wheel on the back. He used it to haul around a gooseneck trailer like a mini-semi truck.
