Chevrolet Impala Convertible
The Chevrolet Impala is a full-size automobile built by the Chevrolet division of General Motors introduced for the 1958 model year. Deriving its name from the southern African antelope, Chevrolet's most expensive passenger model through 1965 had become the best-selling automobile in the United States, competing against the Ford Galaxie 500 and the Plymouth Fury when full-size models dominated the market.
The Impala was distinguished for many years by its symmetrical triple taillights. The Caprice was introduced as a top-line Impala Sport Sedan for the 1965 model year becoming a separate series positioned above the Impala in 1966, which itself remained above the Bel Air and Biscayne. The Impala continued as Chevrolet's most popular full-size model through the mid-1980s. Between 1994 and 1996, Impala was revived as a muscular 5.7-liter V8–powered version of the Caprice Classic sedan. In 2000, the Impala was re-introduced again as a mainstream front-wheel drive full-size sedan.
Totally redesigned in 1965, the Impala set an all-time industry annual sales record of more than 1 million units in the U.S., which has never been bettered. All new full-size Chevys eschewed the "X" frame for a full-width perimeter frame, a new body which featured curved, frameless side glass (for pillarless models), sharper angled windshield with newly reshaped vent windows, and redesigned full-coil suspension Coupe. It was a huge commercial success and would be continued right through 1976.
By 1969, the muscular "Coke Bottle" look had become passe for full-size Chevys. The 1969 Impala and other full-sized Chevrolets got new slab-sided bodies with a small "upsweep" at the rear quarter window, giving them a more formal appearance. The emphasis was clearly on making the Impala look bigger, even though it retained the 119" wheelbase from previous models. New front bumpers that wrapped around the grille and horizontal taillights in the rear bumper made it look wider.
