A 1956 Alfa Romeo 1900 C SS Touring Superleggera coupe, chassis originally delivered to an Italian client in August 1956. Distinctive for its bright yellow-and-black livery — earning the affectionate nickname 'Bumble Bee' — the car passed through German and then American ownership before a cosmetic restoration in 1989. Subsequent preparation as a rally car included drivetrain and suspension upgrades; it has been campaigned in the Tour Auto and California Mille.
