Here's the 1963 Chevrolet Corvair Testudo, which first appeared at the Geneva Motor Show with Nuccio Bertone himself behind the wheel. It was designed in only two months and took the Bowtie Brand into the future with a transparent one-piece windscreen and forward-tilting roof. Since the engine is rear-mounted, the wraparound rear window hinges upward to allow access. Oh, and the headlights are fully retractable -- not bad for 1963.
