Engine
3.0L straight-six, 218 PS
Colour
Graphite Grey

A 1957-build North American-specification Mercedes-Benz 300 SL Roadster, one of 554 completed in the model's first production year. Delivered to the United States in November 1958 finished in Graphite Grey over Cream leather, it spent its early decades on the California coast before passing to a European collection in 1986. The matching-numbers body, chassis, and 3-litre straight-six engine survive intact, though the front chassis crossmember appears to have been replaced at an undetermined point. The interior has since been retrimmed in dark green leather.

Are you the owner of this car?

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.
