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