The body of this vehicle would be delivered as a single flat panel, which would need to be carefully folded -- like really big origami -- and bonded together to form the rigid exterior shell. To keep costs low, the shell could be stamped out from a single sheet of steel or aluminum or some strong but flexible plastic composite. It the drawing below, the windshield, side windows/doors and mounts would be pre-assembled onto the body. Holes for headlights and taillights are already punched out. By the way, If you print out this picture, it can be glued together to form a perfect 3D scale model of this vehicle. I've done it!
