Year to Year Changes
1991 Infiniti M30:
An M30 convertible joined the original coupe this year. Convertibles were transformed from coupes by American Sunroof Corporation in California. A standard power top automatically latched/unlatched at the windshield header and also raised/lowered windows at the same time. Otherwise, improvements were modest in the M30's second season on the market. The central locking system could now be operated from either door, and "summer" performance tires replaced the prior all-season rubber. Tachometer and speedometer positions on the instrument panel were transposed, and gauge graphics were bigger this year.
1992 Infiniti M30:
Except for a new power door-lock system with 2-stage "select logic" operation, this year's M30 coupe and convertible were complete carryovers. All Infinitis got the new door-locking system, in which a "first turn" from either front passenger door locked or unlocked that door. Turning the key a bit farther locked/unlocked the remaining doors.
