P857H33383roadUnited States
Engine
5.7L (347 cu in) OHV V8 with Rochester mechanical fuel injection, 315 bhp
Colour
Raven Black

The 1957 Pontiac Bonneville convertible was a landmark model that transformed Pontiac's image from staid family-car maker to performance contender. Priced at $5,782 and produced in a run of just 630 units, each allocated one per dealer, it was powered by a Rochester fuel-injected 347 cu. in. V-8 producing 315 bhp. This particular example is reportedly the sole fuel-injected Bonneville finished in Raven Black with a black-and-ivory interior, and has been maintained to concours standards following a comprehensive frame-off restoration.

Maintenance & restoration

  1. Restoration

    Complete frame-off restoration carried out to concours standards, with a high degree of factory-correct detail including appropriate engine-bay inspection markings and tags, and a correct original spare tyre with sticker, tonneau cover, and jack.

    Completed more than ten years prior to the catalogue date; the car has seen minimal use since and remains in near-flawless condition.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections. The summary is Legacy Metrics’ own writing; we do not reproduce catalogue text.

“Full” and “partial” documentation labels indicate how well each entry is corroborated in the underlying sources, not an audit of the car’s physical paperwork. Names of recent or living owners are withheld for privacy.
