That fiberglass 911 shell reminded me of a car I raced against in Mexico a bunch of times. It was originally owned by an old guy name Volker Bruckman and with a 3.3L engine in it and was all glass with some sort of tube frame and stamped aluminum floor pan and weighed way less than 2000#! It is currently owned by a VW/Porsche mechanic that lives in Tecate MX and as you can guess it was really fast!
