1978 Chevrolet Corvette â?" Two-Tone Silver/Charcoal, 4-Speed Manual, Red Leather Interior Why This Car Is Special The 1978 Chevrolet Corvette holds a specific and well-documented place in C3 history. This was the 25th anniversary year for the Corvette nameplate, and Chevrolet marked it with a significant redesign of the rear end â?" most notably the introduction of the large wraparound fastback rear window that replaced the previous flying buttress design. That change alone transformed the look of the car and dramatically improved rear visibility. The 1978 model also debuted a redesigned instrument panel and a larger interior storage area behind the seats.
