The Mitsubishi Debonair is a four-door luxury car, introduced by Mitsubishi Motors in 1964 to serve as their flagship passenger vehicle in the Japanese domestic market. Three distinct generations were available during its 35-year production run until it was discontinued in 1999. The first and second generation models were used by senior level executives of the Mitsubishi Group and affiliated companies, or essentially a Mitsubishi senior executive company car made by the motor vehicle division of Mitsubishi. In Japan, it was sold at a specific retail chain called Galant Shop.
