Now it was ready to introduce the Mitsubishi 500, a mass-market sedan, to meet the new demand from consumers. It followed this in 1962 with the Minica kei car and the Colt 1000, the first of its Colt line of family cars, in 1963. In 1964, Mitsubishi introduced its largest passenger sedan, the Mitsubishi Debonair as a luxury car primarily for the Japanese market, and was used by senior Mitsubishi executives as a company car.
