- Cream and black

Bugatti Type 57 chassis 57731 is a one-off four-passenger cabriolet bodied by Gangloff of Colmar to a design by Lucien Schlatter, completed in October 1938 and exhibited at the 1939 Geneva Motor Show on the factory stand. Thereafter used as a works demonstrator, it was made available to celebrated Grand Prix driver Jean-Pierre Wimille. After post-war obscurity it passed through the hands of noted Bugatti trader Paul Sac before entering the Quattroruote Collection in 1964, where it remained for over five decades. The car retains its original engine and is documented in multiple authoritative Bugatti registers.

Maintenance & restoration
- —Restoration
The car underwent a full restoration at an undetermined point, resulting in the current cream-and-black livery; described as an authentic older restoration in presentable cosmetic and mechanical condition.
The chassis number plate shows a later stamping of '731', believed by historian Kees Jansen to have been made very early in the car's life, possibly at the time of or shortly after this restoration.
