The Corvette C3 was chosen as the pace car for the 1978 Indianapolis 500. Initially, 2500 Indy 500 replica pacers—100 for each year of production—were scheduled for sale. But it was decided that each of Chevrolet's 6200 dealers should have one for showroom display. Thus what was called the Limited Edition Indy Pace Car Replica Corvette made up some 15 percent of total production. Like the Silver Anniversary model, the Pace Car Replica was actually an option package-RPO Z78. Its main distinction was black over silver metallic with a bright red pinstripe in between with a spoiler added to each end to alter appearance more dramatically. Pace car interiors reflected Bill Mitchell's influence, with full silver leather or silver leather/gray cloth upholstery and gray carpeting. All replicas were equipped with new thin-shell design-lumbar support seats, new glass t-tops, alloy wheels, power windows, air conditioning, tilt/telescope steering wheel, power locks, rear defogger, sport mirrors, heavy-duty battery, and AM/FM stereo with either eight-track tape player or CB radio. The final touch was the Indy 500 decal set included uninstalled with each limited-edition car.
