Buick revealed the Super Series in 1955 and began full production on its Riviera models a the same year. The Super models were available with three body configurations: four-door sedan, two-door Riviera Hardtop and two-door convertible. The Super Riviera Sedan was introduced later in 1956 and featured an 122-inch wheelbase and a 2.6L V8 engine delivering a massive 255 hp. This model featured some slight exterior and interior restyling during its three years of production until it was finally discontinued in 1959. This model was one of the most successful in the series as its base model price began from just under 3,500$.
