Buyer’s notes
About the Pontiac Bonneville (1957)
The 1957 Bonneville, properly the Star Chief Custom Bonneville, was Pontiac’s most exclusive model. It was built only as a convertible, only 630 were made, and every one had a fuel-injected 347 cu in V8 with Rochester fuel injection. The next year Bonneville became a model line of its own.
What moves the price
- Authenticity: a genuine 1957 car with its original fuel-injected engine is the whole point.
- Documentation proving the car’s identity and history.
- The quality and correctness of any restoration.
Before you buy, check
- The car’s identity and its fuel-injection system against Pontiac records and specialist advice.
- Corrosion in the floors and lower body.
- The power equipment and convertible top in working order.
