Elio Addict
The only jig they'll need is for the frame. If the frame is modeled (and it most certainly is), then the jig can be easily modeled around the frame, including accurate tolerances (pick a decimal point below zero, mine goes to nanometers), including the order the structural parts need to be loaded. They'll probably have a human do the tack welding, and leave the finish welding to robots. All this, including the robot's arm movements can be done "Virtually" and checked for errors before a single spark flies. Everything else on the Elio is either bolted or glued on and requires minimal tooling (if any).
