I was just wondering since tuners make conversion and full kits for cars ie. AMG, Brabus, Veilside, AC Schnitzer, Rinspeed, callaway. etc. why doesn't a tuner or kit car manufacturer just work with existing composite body cars to make things easier? Like the Lotus Elise or corvette? Most if not all the panels come off, and you can work with a reliable and existing frame, engine, electronics etc to make what ever body you wanted. Am I missing something?
