Mitsubishi Debonair V6 3.0L

The Mitsubishi Debonair was a quintessential Japanese luxury sedan that served as Mitsubishi's range-topping model from 1964 through 1992. While the first generation persisted largely unchanged for over two decades, the second generation launched in 1986 was a thoroughly modern machine featuring a transverse-mounted 3.0-liter 6G72 V6 engine driving the front wheels.

The Debonair was primarily designed as an executive chauffeur car for Japanese business executives. Its rear seat accommodations were the focus, with generous legroom, reclining seats, and available reading lamps. The interior featured wood trim, plush velour or optional leather upholstery, and electronically adjustable suspension for a serene ride quality.

Competing against the Toyota Crown, Nissan Cedric, and Honda Legend, the Debonair was the least commercially successful of the group. Mitsubishi's smaller dealer network in Japan limited its reach, and the car was never officially exported. This domestic-only status and limited production make surviving examples quite rare today.

The Debonair name was retired in 1992 when it was replaced by the Proudia (and later, Mitsubishi simply rebadged the Hyundai Equus for its flagship needs). As a piece of Japanese automotive history, the Debonair represents Mitsubishi's ambition to compete at the highest level of domestic luxury, and clean examples are prized by collectors of obscure JDM prestige cars.

$5,000 – $20,000

Extremely rare, even in Japan. Finding one in good condition requires patience and Japanese auction access. The 6G72 V6 is shared with many Mitsubishi models so engine parts are available, but body panels and interior trim are nearly impossible to source. Check for rust thoroughly as most survivors have spent decades in Japan. Automatic transmission should shift smoothly; rebuilds require specialist knowledge. Electronic suspension components may have failed and been bypassed.

The first generation (1964-1986) had one of the longest production runs of any Japanese car with minimal changes. The second generation (1986-1992) was a complete redesign. Never exported; sold exclusively through Mitsubishi's Galant Shop dealer channel in Japan. Replaced by the Proudia in 1999.
