While Pontiac was best known as a maker of solid, conservative cars for much of its early history, that image changed forever with the all-new 1955 models. The chassis was entirely redesigned, with the frame extended and cloaked with distinctively styled bodies. Performance was now emphasized, with the old straight eight replaced by an all-new, compact and very powerful overhead-valve V-8 engine.

The top-line Star Chief series was available in four-door sedan and two-door convertible form, while the Star Chief Custom series included a four-door sedan and the very popular two-door Catalina hardtop. Pontiac achieved sixth place in manufacturer rankings for 1955, holding that position through 1957 and ultimately becoming the third-place American marque for much of the 1960s, based on its performance focus.

Soon, Pontiac released a number of high-performance engine and drivetrain options, specifically intended for NASCAR competition. On the street, the 290-horsepower Tri-Power V-8 was capable of propelling the Star Chief from 0- to 60-mph in 8.5-seconds, en route to 16.8-second quarter-mile times – an impressive performance for any era.

This 1957 Pontiac Star Chief Convertible is a great example of early Pontiac performance with its desirable 290-horsepower, 347-cubic inch Tri-Power V-8 engine routed through dual exhausts. It is finished in Sheffield Gray and Tartan Red paint with a similar two-tone interior. Features include an Autronic-Eye, under-seat heater, deluxe AM radio, factory clock, fender skirts, whitewall tires, factory wheel covers; power top, brakes and power steering. It is reported to run and drive very well and seamlessly combines Pontiac performance with timeless styling.
