This 1957 Pontiac Bonneville is one of approximately 630 convertibles built during the first year of production and is finished in Kenya Ivory with red side spears over a red and white interior. Power is supplied by a fuel-injected 347ci V8 paired with a Hydramatic four-speed automatic transmission, and equipment includes a power-folding white soft top, electric windows, a power-adjustable driver’s seat, power steering, a push-button Wonderbar AM radio, and rear fender skirts. The car reportedly underwent a refurbishment prior to its acquisition by the selling dealer around three years ago. This Bonneville is being offered in Hyannis, Massachusetts with manufacturer’s literature and a clean Pennsylvania title.
The exterior is finished in Kenya Ivory with red side spears and was repainted some time during previous ownership. Exterior features include a power-folding white soft top, a retractable antenna, fuel injection badging, and rear fender skirts.
Red-painted 14” steel wheels feature chrome covers and are mounted with 225/75 Coker Classic wide whitewall tires. A full-size spare is found in the trunk.
The cabin features seats trimmed in red and white vinyl with matching door panels and red carpets lined with black rubber mats. Amenities include a power-adjustable driver’s seat, power steering, electric windows, and a Wonderbar push-button AM radio.
A white two-spoke steering wheel with a chrome horn ring shows signs of cracking and frames a horizontal 120-mph speedometer along with auxiliary gauges for battery charge, coolant temperature, fuel level, and oil pressure. The five-digit odometer shows 500 miles, around 70 of which have been added by the selling dealer over the last three years. Total mileage is unknown.
The 347ci V8 is equipped with Rochester mechanical fuel injection and was factory rated at 315 horsepower. The selling dealer notes that an oil change was performed in late 2019.
Power is sent to the rear wheels through a Hydramatic four-speed automatic transmission. Additional underbody images are provided in the gallery below.
