The Mercury Grand Marquis was in production from 1975 through 2011. The first generation was built from 1975 to 1982 and served as the company's premium model of full-size sedans. The Ford counterpart was the Ford LTD, serving as a replacement for the discontinued Monterey with trim levels including the Brougham and top-of-the-line Grand Marquis. Power was from a 460 cubic-inch V8 with 4-wheel disc brakes optional on all four corners.
The Mercury Marquis had a 124-inch wheelbase and the station wagons rested on a 121-inch platform. For 1977, the base Marque engine was an overhead valve V8 displacing 400 cubic-inches and producing 173 horsepower. The Grand Marquis had a 460 cubic-inch unit with nearly 200 horsepower and 353 ft-lbs of torque. A SelectShift automatic was standard. The engine had DuraSpark ignition and a new coolant recovery system.
The changes to the 1977 Marquis were minimal and mostly cosmetic. New interior fabrics and body colors became available. Body styles on the base trim level included a hardtop, 4-door pillarless hardtop, and 6- and 8-passenger station wagons. The Brougham and Grand Marquis were a hardtop and 4-door pillarless hardtop. Total production reached 156,032 examples which accounted for 27-percent of Mercury's total 583,055 calendar year sales by U.S. dealers. New options for 1977 included an illuminated entry, AM/FM stereo radio with Quadrosonic 8-tape player, power moonroof, high-altitude emissions, simulated wire wheel covers, and whitewall radial tires. The Colony Park wagon was now an optional package on the Brougham trim level.
The Grand Marquis had power windows and tinted glass, a vinyl roof, fender skirts, Twin Comfort Lounge seats, a digital clock, automatic parking brake release, and paint stripes on the hood and decklid. Standard equipment on the base Marquis included blackwall steel-belted radial tires, power steering, and power brakes. The Marquis Brougham had a full vinyl roof on four-door body styles, a landau vinyl roof on two doors, fender skirts with molding, a clock, additional molding, and power windows.
