A Mercedes-Benz 300 D Cabriolet, one of the rarest and most opulent variants of the post-war 300 series, built on 31 December 1952 for the US market in a special-order Dark Green over grey-green leather combination. Retaining an exceptionally rare Becker Nürburg III six-band radio, the car passed its first three decades with one family before a concours-grade restoration was commissioned in 1999. Subsequent ownership by marque authority Tom Hamilton produced multiple Best in Class awards at prominent American concours events.

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.
