Once the decade of the 1990s got rolling, the Lexus LS400, Toyota Cressida, Infiniti Q45, Acura Legend and Mazda 929 had proven that big Japanese-made luxury sedans could rack up respectable sales in the United States. Mitsubishi dove into that competition starting with the 1992 model year, when the Diamante arrived on our shores. Here’s one of those early Diamantes, found in an Oklahoma City car graveyard recently.
Mitsubishi had been selling big, swanky Debonairs at home since the middle 1960s, but that car was never sold new in North America (though a Debonair-related Hyundai, the XG300/XG350, did show up here).
The Diamante was based on an enlarged Galant/Sigma platform and was available here as a pillared hardtop four-door sedan (in which there is a narrow B pillar but the door windows are frameless) and as a station wagon. The US-market sedan was built in Japan, while the wagon came from Australia.
