1984 Mercury Grand Marquis


Featured image for “1984 Mercury Grand Marquis”

The Mercury Grand Marquis is an automobile that was sold by Mercury from 1975 to 2011. Introduced as the flagship sub-model of the Mercury Marquis, the Grand Marquis became a stand-alone model line for 1983, serving as the largest Mercury Colony Part station wagon; it would later serve as the basis of the revived Mercury Marauder.

From 1979 until 2011, the Grand Marquis shared the rear-wheel drive Panther platform with the Ford LTD Crown Victoria (Ford Crown Victoria after 1992), and from 1980, the Lincoln Town Car. For over three decades, the two model lines were functionally identical, with two of the tree generations of the model line sharing a common roofline. Offered nearly exclusively as a four-door sedan, a two-door sedan was offered from 1975 to 1987.

For 1979, Mercury downsized its full-size model line for the first time, with the Grand Marquis making its return as the premium model of the Mercury Marquis model range. Seventeen inches shorter and nearly 100 pounds lighter (dependent on powertrain) than its 1978 predecessor. While its exterior footprint closely matched the Cougar (Montego) intermediate sedan, the 1979 Grand Marquis saw gains in interior and luggage space.


This vehicle came in for some engine work, replace the shocks, felts & sweeps, new door seals, diagnose leaks and some interior upholstery work.


The rear brakes have been removed to replace with new drum brakes.

We have removed the old trunk seal and replaced it with a new seal.
