The Mercury Marquis was a series of full-size, and then later mid-size, cars introduced in 1967. The Marquis was Mercury's flagship model until 1982, when Mercury made the Grand Marquis its own model. Prior to 1982, the Grand Marquis had been a trim level for the Marquis. The Mercury Marquis was produced in four generations: 1st Gen (1967-1968), 2nd Gen (1969-1978), 3rd Gen (1979-1982), and 4th Gen (1983-1986).
