The Mercury XM-800 concept car was designed by John Najjar and first exhibited at the 1954 Chicago Auto Show. The design of the XM-800 heavily influenced Lincoln and Mercury's 1955 and 1956 models. The 1955 Mercury used a 119-inch wheelbase body. Ford's new Y-block V8 was given to the Monterey in 4,778cc (292) for 1955 and 5,115cc (312) for 1956. The Monterey was launched as a 4-door sedan, 2-door and 4-door hardtop, station wagon and convertible. From 1952 the Monterey had been Mercury's top model line but from 1955 it sat below the new Montclair model.

Buick Special 1955 Sedan. In 1954 a new Fisher body was developed for GM's B-body cars, and shared between the Buick Special and Oldsmobile 88. In 1955 both cars were given their annual update. It is possible that 'spies' from the British Rootes Group saw this design and plagiarised it for what they regarded as the 'British Buick', the Humber Hawk/Humber Super Snipe.
