Mark O, I did hear of cars made from soft, pliable plastic (not fibreglass) Some makes were even with replaceable panels ! Article and Photo below: Chrysler’s Composite Concept Vehicle (CCV) Chrysler's latest concept car (figure 1)might look like your average urban runabout, but even just a cursory tap on the bodywork will tell you that this vehicle is something different. For although the design breaks little new ground, the Composite Concept Vehicle (CCV) is made from radically different materials to the norm, with the body being built almost entirely from plastic. Chrysler hopes the CCV will herald a new generation of lightweight, fully recyclable plastic cars that are cheap to run and extremely fuel efficient.
