A left-hand-drive 1957 Mercedes-Benz 190 SL Roadster, chassis 121040-7500658, manufactured in April 1957 for the American market. Part of the acclaimed 1955–1963 production run of nearly 26,000 examples, it is powered by the 1,897cc overhead-camshaft M121 four-cylinder engine. The car underwent a comprehensive restoration completed in 2018, returning it to its original red paintwork with black fluted leather interior, and has since received specialist tuning by PT Classics.

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.
