Pontiac was in the midst of an image makeover in 1957. Just three years earlier, Pontiac had been a stodgy solid-citizen car for the senior set. In 1955, Pontiac introduced its overhead-valve V8, and by 1957, Pontiac was making a name for itself on the nation's racetracks.
To celebrate this ongoing performance revolution, Pontiac announced the Bonneville Custom Convertible in the spring of 1957. It was powered by a 347 cubic-inch V8 with Rochester fuel injection and a 317 horsepower rating.
The Bonneville's factory list price was an astronomical $5,782 ($2,677 more than a regular-production Star Chief Convertible). For that Cadillac-like price, Bonneville buyers got a Cadillac-like level of standard equipment, including Hydra-Matic automatic transmission, power steering, power brakes, eight-way power seat, Wonderbar radio, tri-blade wheel covers and a full leather interior. Distribution was limited to select Pontiac dealers and only 630 were built.
The Bonneville shown is Kenya Ivory with a Fontaine Blue side spear and Blue/Ivory leather interior.
