Chassis 7500079 is the final Mercedes-Benz 300 SL Gullwing produced, completed on 15 May 1957. Built as a special-order show car, it was displayed at the 1957 Poznan International Trade Fair before entering the US distribution network in September of that year. Finished in Fire Engine Red over full Crème leather with English instrumentation and Roadster-specification Kronprinz wheels, it has passed through only four recorded owners since new, retaining its numbers-matching drivetrain and factory colour scheme. A private restoration by its most recent long-term custodian earned third place in class at the 2004 Pebble Beach Concours d'Elegance.

Maintenance & restoration

  1. Restoration

    Comprehensive multi-year restoration carried out personally by the long-term private owner, completed to a standard that earned a class placement at Pebble Beach in 2004.

This car's public record is built from its auction and competition history. Register your ownership and privately add your own records to make it a verified Legacy Metrics passport — provenance that backs your car's value at sale and gives your insurer evidence to price against. Roy reviews and verifies every registration personally.

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.
