1956 Jaguar XK 140 Ghia Supersonic Coupe (coachbuilt)
- Engine
- Dual SU carburetors, numbers-matching unit (displacement and cylinder count unspecified)
- Colour
- Red over tan leather interior

One of at most four Jaguar XK 140 chassis clothed by Ghia of Turin in the Supersonic-derived coachwork style, this car carries chassis number S 815404 and was completed in 1956. Ordered new through Los Angeles dealer Hornburg, it later passed to entertainer Gower Champion and his wife, then to actor Ricardo Montalbán in 1967. After a period in Japan, it entered the Blackhawk Collection, where it appeared twice at the Pebble Beach Concours d'Elegance. It retains its numbers-matching, dual-SU-carbureted engine.

Maintenance & restoration
- —Restoration
The car was comprehensively refurbished to its current configuration: red bodywork over a tan leather interior, with period-correct Marchal headlamps retained and the numbers-matching dual-SU engine and cylinder head preserved.
The work is described as having been completed by the time the car appeared at Pebble Beach in 1992; it was carried out during the Blackhawk Collection's stewardship.
- —Modification
A bonnet air intake was added at an undetermined point, bringing the car's appearance into closer alignment with at least one other known Ghia-bodied XK 140 example.
The intake was absent during Montalbán's ownership, so it was fitted at some later stage.
