The Pontiac Bonneville name was given to a 1954 GM Motorama concept car based on the Chevy Corvette. The concept never became a production car, but the Bonneville name was applied to a trim level on the 1957 Pontiac Star Chief. The Bonneville was the fuel-injected convertible version of the 1957 Star Chief, and it came standard with almost every available option with the exception of the continental kit and air conditioning. The following year, the Pontiac Bonneville would become its own model, available as either a two-door hardtop or convertible.
Our feature 1957 Pontiac Bonneville convertible is one of just 630 Bonnevilles built for the model year, one for each Pontiac dealership. It is finished in Kenya Ivory with red side insert over a two-tone red and white leather interior and a white vinyl convertible top. Chrome and stainless are both brilliant in bright sunlight. Rearview mirrors ride just forward of the windshield on the front fenders. The Bonny rides on red-painted steel wheels with full wheel covers shod in wide whitewall bias-ply rubber.
Powering the Pontiac Bonneville is a 347 cubic-inch Small Block V8 fed by a Rochester mechanical fuel-injection system. The 347 is backed by a Strato-Flight Hydra-Matic automatic transmission. The Bonneville is equipped with power steering, power brakes, and a power convertible top.
Inside the Pontiac Bonneville is a brilliant two-tone bright red and white leather interior with deluxe red carpet. The dash is home to a brushed metal panel that surrounds the speedometer, gauges, and Wonderbar signal-seeking radio. A power antenna brings in the tunes. Eight-way power seats make getting comfortable a breeze.
This 1957 Pontiac Bonneville convertible will cross the Mecum Auctions block at their Las Vegas, Nevada event taking place November 10th through the 12th.
