- Colour

Chassis 57798 is a 1939 Bugatti Type 57C bodied as an Aravis cabriolet by Gangloff — one of only three surviving examples of this rare style. Originally commissioned by Dr. André Chauvenet, a Bugatti devotee and decorated wartime resistance figure, the car passed through Swiss ownership before being converted to a fixed-head coupé in 1959. A meticulous seven-year restoration completed in 2001 returned it to open cabriolet specification with its supercharged straight-eight engine rebuilt to original form.
