For 1969, the Monterey’s wheelbase grew to 124 inches (315 cm) inches with the exception of the station wagon which was on the 122 inches (309.9 cm) Ford wheelbase – it was essentially a Ford wagon with a Mercury front clip and trimwork. The redesigned Mercurys were intended to emulate the Lincoln Continental. Minor changes differentiated the 1970 models, but a restyle for 1971 resulted in rounded and more flowing bodywork, beaked grilles, flipper exterior doorhandles, frameless windows on all sedans, wider c-pillars and fender skirts on all but the base Monterey and wagons. The convertible bodystyle for both the Monterey and the Marquis was eliminated and replaced by the new, costly and very rare optional power moonroof which was first made available on a Mercury with the 1968 Cougar. 1972 brought minor changes to Monterey and Marquis, such as eggcrate grilles and a front seatbelt warning buzzer. Also, SelectShift Cruise-O-Matic transmission, power steering and power front disc brakes became standard equipment on all Monterey models for 1972.
