1984 was the first fourth-generation Corvette; 1982 was the final third-generation vehicle. As the first truly European-style Corvette, the 1984 got tremendous praise. Why then do the 1982 and 1984 Corvettes be treated so poorly?

1982 C3s had problems with power door locks and pigtail switches.

1982 C3 vehicles had crossfire, fuel pump, battery, taillight, and marker light issues.

The 5.5L crossfire V-8 is to blame. Crossfire fuel-injected Corvettes are reliable and powerful.

Corvette was similar. The V-8-powered Corvette has burned tires since 1965. By 1974, the big block V-8-powered Corvette had 270 HP, making it like an out-of-shape performer.

Just about, it was the fastest 1974 Corvette. It could travel from 0 to 60 mph in 6 seconds and 4 seconds, compared to the normal 1974 Corvette’s 6 seconds and 8 seconds.

Beware of critics. 1974’s LS Four Corvette was fast. The 1974 LS Four Corvette is a fantastic deal if you’re looking for a large block Corvette at a fair price.
