1952 Mercedes-Benz 300 S Roadster

188.012.00309/53roadGermany
Engine
3.0L inline-six with three Solex carburetors, uprated compression, 150 hp

One of just 141 examples of the Mercedes-Benz 300 S Roadster produced between 1952 and 1958, this car was delivered new in Europe before making its way to the United States during the 1950s. It spent 63 years with a single Northern California family across three generations, accumulating an appealing long-term patina. Notably, it was converted early in its life to a floor-shifted configuration similar to that found on the 300 SL. A recent mechanical service and light cosmetic work have been carried out without disturbing its original character.

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.
