After working on them for so long, those areas around the doors are very sturdy. Those and the heater channels provided all of the support for the car itself (thus no "frame"). Those VW 5th wheels couldn't have weighed much, either (although that bug backend is sitting pretty low). I don't see that bug going very fast with all of that added wind resistance!
Cool item, though! Thanks for sharing!
