The fourth-generation Marquis was produced as a four-door sedan and as a five-door station wagon (the two-door was discontinued, with the Cougar becoming the sole Mercury mid-size coupe.
 Sharing its entire bodyshell with its Ford LTD, the Marquis was distinguished by its own grille, taillamps, and parking lamp lenses.
 For the 1985 model year, the Marquis underwent a minor exterior revision; along with revised taillamps, Mercury lettering in the grille was replaced with a centered crest emblem.

The interior of the Marquis and LTD was largely shared between the two model lines (with the exception of the interior door panels).
 To save development costs, the Marquis retained the dashboard design of the Cougar XR-7 coupe (mixing wood and silver trim), adopting its electronic instrument panel option.
Adopted from the full-size Marquis and the Cougar XR-7, the Marquis continued the use of an electronic trip computer.
