I agree with your analysis CrazyJerry. Foam core construction is the way to go for a one off build. Riley offers a good overview of the technique on his website and you can purchase the XR3 plans that offer a more in depth look into how its done with an accompany DVD of them working on the XR3 body. Another source that uses the same concept but instead of using plywood formers they utilized aluminum honeycomb is the Trev gang out of Australia. Here are a few good links that shows how they did there foam core body construction

part #1 = AutoSpeed - Building an Ultra Light-Weight Car, Part 1

Part #2 = AutoSpeed - Building an Ultra Light-Weight Car, Part 2

If you were going to mass produce the vehicle then plugs and molds are the way to go. These can easily be taken from the original composite piece or in the case of the Urba Centurion the entire car could have molds taken and replicated. However the plans clearly state that its for one build only and can not be duplicated in a mass production setup. This is the case for all of the RQ Riley plan sets which are build it yourself designs not kit cars. Kit cars have the body kits complete you need to fit them to the appropriate donor chassis. RQ Riley designs need to have the body fabricated this is a big difference compared to a body kit like the Fiberfab kits mentioned by CrazyJerry. Fiberfab offered what was called the Jamaican kit car which was based off the Triumph Spit/GT6 chassis like the Urba Centurion. If you google the Jamaican Fiberfab kitcar you can view its pics. They were actually well done and IMO looked better than the original which most of the time is not the case.

CrazyJerry I love the pics bro keep em coming :-)
