The Mercury Marquis is a model line of automobiles that was marketed by the Mercury division of Ford Motor Company from the 1967 to 1986 model years. Deriving its name from a French nobility title, the Marquis was introduced as a rebadged counterpart of the Ford LTD, retaining a similar market position across four generations of the model line. Initially serving as the flagship Mercury range, the Marquis line was later expanded to include the Mercury Grand Marquis positioned above it; in various forms, Mercury would use the nameplate through the 2011 model year. For the first three generations of the model line, the Marquis served as the full-size Mercury sedan line (alongside the Mercury Colony Park station wagon). The fourth generation was the mid-size sedan for the division, following the 1983 split of the Marquis and Grand Marquis into distinct product lines. As Ford expanded its front-wheel drive product ranges, the Marquis was withdrawn after the 1986 model year and replaced by the Sable (the Mercury rebadged counterpart of the Ford Taurus). For its first three generations, the Marquis was produced in Hapeville, Georgia (Atlanta Assembly), Hazelwood, Missouri (St. Louis Assembly), and Pico Rivera, California (Los Angeles Assembly); the fourth generation was produced by Atlanta Assembly and in Chicago, Illinois (Chicago Assembly). First generation (1967–1968) For 1967, Mercury introduced two hardtop model lines above the Park Lane to serve as the counterpart of the Ford LTD. The Park Lane Brougham was a four-door, with the Marquis offered solely as a two-door. While all full-size Mercury two-doors were hardtops, the Marquis was fitted with a standard vinyl roof giving it a wider C-pillar. While sharing a roofline with the Ford LTD, the Marquis differed from its Ford counterpart from the use of higher-specification interior trim (wood trim in place of simulated wood, optional leather unavailable on the LTD). As with other Mercury sedans, the Marquis was built on a 123-inch wheelbase (4 inches longer than the LTD). In contrast to the full-width bench seat of other Mercury lines, the Marquis was fitted with "Twin Comfort Lounge" front seats. Designed as a 50/50 split bench seat, the design combined the 3-passenger capacity of a bench seat with the individual legroom adjustment of bucket seats. In various forms, the design would gradually replace traditional bench seats in many American cars during the 1970s and 1980s. Mechanical details For 1967, the standard engine
