1973 Corvette Production Numbers
The 1973 C3 Corvette was the sixth year of the C3 generation. In total, 30,464 Corvettes were produced for the 1973 model year, representing an increase of 3,460 over the 1972 Vette. Of those 30,464 cars, 25,521 were coupes, and 4,943 were convertibles. The base price of a 1973 C3 Corvette was $5,561.50 for the coupe and $5,398.50 for the convertible, and it included a 350 cubic inch, 190-horsepower engine. It also included the 4-speed wide-ratio manual transmission, soft top (convertible), or T-tops (coupe), and it came with vinyl interior trim.
Body Styles and Trim Levels
By the 1973 production year, Corvette was in the midst of transforming from the chrome bumper era to a new look. Due to new federal collision safety requirements, 1973 models wore plastic front bumpers while still sporting chrome rear bumpers and side-impact door beams. To adhere to new safety requirements, the front chrome bumper of the car was replaced with a 5-mile-an-hour bumper that resulted in an extra 35 pounds and significantly changed the car’s appearance. It is the only year in which a rubber front bumper and chrome rear bumper were used simultaneously.
The small spoiler at the back of the car was also removed this year.
