The MS-8 is a hardtop-style sedan in the vein of the Toyota Cresta, Nissan Laurel, Honda Vigor, and Mitsubishi Emeraude.

The car is only fitted with a 4-speed automatic gearbox, and the gear shifter is mounted on the dashboard next to the air-conditioning controls.

The display for climate control and factory-equipped audio is located atop the dashboard, in a thin slit right before the windshield defroster.

The stereo and CD player were concealed behind a retractable cover in the center of the dashboard below the air conditioning controls, however, simple functions like the volume, music source (radio or CD player) and music selection controls were installed remotely on the steering wheel.

Production for the MS-8 ceased when Mazda's multi-brand strategy failed in Japan, and the company suffered financial difficulties.
