1958 Chevrolet Impala Sport Coupe with a 348 V-8

From the inaugural year of the car so famously named after the speedy antelope from southern Africa, this 1958 Chevrolet Impala Sport Coupe is described as a fully numbers-matching example that has won multiple accolades, including best in class at an AACA judged show in Waterbury, Vermont, and a star turn on the show field at our own Hemmings Concours d'Elegance. Very strongly presentable, with a Continental kit at the rear, this Impala is said to retain its factory-original interior. It is unusually optioned with the Turboglide transmission, an early planetary-gear take on a three-speed automatic that Chevrolet offered between 1957 and 1961, and which is usually considered a three-speed due to its trio of drive turbines. The car wears a repaint that's believed to be about six years old. - Chevrolet needed more power than its workaday small-block V-8 could provide in the emerging Detroit horsepower race, so it introduced the larger-displacement W series of V-8s in 1958.
