In 1971, the Mercury full-size model range underwent a exterior restyling. While retaining the roofline shared with Ford, the Monterey adopted design elements similar to the larger Lincoln Continental, included its wide-pointing grille and taillamps. In a major change, Ford and Mercury introduced "pillarless hardtops", using frameless door glass on both hardtops and four-door sedans; vent windows were discontinued. Redesigned door handles no longer protruded from the exterior; rear fender skirts were standardized on all full-size Mercury sedans except the base-trim Monterey. The Monterey and Marquis convertibles were discontinued for 1971, leaving the Cougar as the sole Mercury convertible.
