Numbers-matching throughout and confirmed by a Mercedes-Benz Zertifikat, the car has had just three owners from new and received an exhaustive, no-expense-spared restoration completed in 2010 by marque specialist Don Mertz.

    Don Mertz

    A comprehensive, no-expense-spared full restoration covering bodywork, interior, engine bay, and chassis. All brightwork was refinished to a high standard, the cabin was retrimmed in leather and wool carpeting with burled wood details, the triple-carburettor engine was meticulously detailed with correct markings, and a period-correct canvas cabriolet hood was hand-fitted. Chassis and underside details were also addressed to a correct specification.

    Extensive supporting documentation including invoices and photographs accompanies the car. The restorer is described as a respected marque specialist.

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.
