Yes, that's true -- I posted a thread with the underside of a Noble M12 GTO. But openings make it less of a mechanics nightmare, unless you need to repair a weld (which is the reason I was able to get the photos I did). But having the drive train above the frame (not sure if that makes sense, but I think I know what you're saying) doesn't change that you're adding a LOT of stiffness VIA geometry by rigidly fastening an under tray (recall the recent Ford ads for "closed box frame rails").

Glue Screwed and Riveted







And then, there's the Elise.
