1935 Mercedes-Benz 500 K Three-Position Roadster (Windovers coachwork)

123699roadGermany
Engine
Supercharged straight-eight
Colour
Black over black (previously red and black)

A 1935 Mercedes-Benz 500 K chassis (no. 123699) carrying a unique Three-Position Roadster body by British coachbuilder Windovers, one of only two similar bodies they fitted to the 500 K platform. Ordered originally by William 'Willie' Rhodes-Moorhouse — Olympic skier and RAF Battle of Britain hero — the car features sweeping pontoon fenders, a tapered tail, and an ingenious folding roof design. With its original engine intact and a documented chain of ownership, it is regarded as among the most distinctive of all surviving supercharged Mercedes-Benz automobiles.

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.
