1936 Bugatti Type 57 Stelvio Cabriolet
- Colour
- Royal blue with black sweep panel

A 1936 Bugatti Type 57 Stelvio cabriolet, chassis 57406, bodied to Jean Bugatti's elegant four-passenger design with characteristic pontoon fenders and a rounded tail. Exhibited at the Nantes International Fair before its first sale, the car passed through several French owners before entering the collection of Alexander Ulmann — founder of Sebring and a towering figure in American motorsport — who kept it until his death in 1986. A subsequent West Coast restoration returned the car to a two-tone blue scheme with grey leather interior. The original engine, rear axle, and transmission survive.

The car was dispatched by the factory to this trade exhibition prior to its first retail sale in August 1936.
Maintenance & restoration
- —Modification
The car received updated later-style headlamps integrated into the front fenders, rear wheel spats, front bumper moustaches, and a conversion to Lockheed hydraulic brakes from the original cable-brake system. The standard of work suggests factory or authorised agent involvement.
Period photographs from the 1940s confirm these changes were already in place by that time, consistent with 1937–39 Bugatti practice.
- —Restoration
A comprehensive restoration carried out by the West Coast collection updated the livery to a two-tone royal blue and black sweep-panel finish, fitted pale grey leather upholstery, reinstalled the rear wheel spats, and chromed the wire wheels in the manner available from Bugatti from 1937.
The odometer reading of 1,047 kilometres is believed to represent distance covered since this restoration was completed.
