1939 Mercedes-Benz 540 K Cabriolet A

408388roadGermany
Engine
Supercharged straight-eight

A late-production Mercedes-Benz 540 K Cabriolet A, built in third-series coachwork style with deeply skirted rounded fenders, and equipped with the desirable five-speed gearbox. Delivered new in Berlin in September 1939, the car subsequently spent decades in Brazil before moving to the United States in the 1980s. It retains original factory identification tags, the original engine number stamping, and period Bosch lighting, presenting as a largely cosmetically restored survivor with an intact drivetrain.

Maintenance & restoration

  1. 1994
    Bodywork

    The car was refinished to its current two-tone colour scheme around the time it entered the present collection; the restoration appears to have been primarily cosmetic in scope, leaving original mechanical identification tags and engine stampings undisturbed.

    The dashboard covering was also replaced at some point, though the leather upholstery and interior woodwork were retained and show light patina consistent with age.

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.
