Which of these Chevrolet cars was discontinued in 1977?

As one of Chevrolet's most successful nameplates, the Chevelle can never be forgotten, even though it officially left the market in 1977. The Chevelle Super Sport and Laguna versions are the favorites of classic car collectors, and they still have a pretty high demand to this day. Across three generations, from 1963 to 1977, the Chevelle got its motivation from more than six engines, including a big-block V8.
