1972 Chevrolet Corvette Stingray â?" Matching Numbers 350 V8, Pewter Silver, T-Tops Why This Car Is Special The 1972 Chevrolet Corvette Stingray occupies a specific and well-understood place in C3 history. It was the last model year before federally mandated bumper standards began to reshape the car's appearance, and the last year Chevrolet used the traditional gross horsepower rating system before switching to the lower net figures in 1973. That context matters to collectors, because the 1972 Corvette is widely regarded as one of the cleaner, less-compromised examples of the C3 generation. Chevrolet built 20,496 Corvettes for the 1972 model year, split between coupes and convertibles.
