One of the largest cars ever produced by the Mercury division, the 1959 Montclair was criticized by owners for lack of interior room (relative to its size), poor fuel economy, and its windshield design. For 1960, Mercury sedan underwent their second major exterior revision in two years, adopting more restrained styling (nearly removing the tailfins altogether). The Montclair Cruiser two-door and four-door hardtops were carried over, along with the four-door Montclair sedan. Shared with the Colony Park and the Park Lane, the 430 V8 made its return as the standard engine (retuned to 310 hp). Discontinuation For the 1961 model year, to build a better business case for Lincoln-Mercury within Ford, both the Mercury and Lincoln brands underwent a substantial revision of their model lines, with Mercury discontinuing the Montclair and Park Lane in favor of the Monterey as its primary sedan line, joined by the full-size Meteor and the compact Comet, two designs originally intended for production as Edsels. In a larger change, the 1961 Mercury (both the Monterey and Meteor) adopted a Ford bodyshell and chassis (using its own wheelbase and slightly modified styling). Until the closure of the division after 2010, Mercury full-size sedans were variants of the full-size Ford model line. Fourth generation (1964) For 1964, the Montclair nameplate was revived, again as the mid-level full-size Mercury sedan (positioned between the Monterey and a revived Park Lane). The 1964 Mercurys underwent a minor facelift, as a convex grille replaced the previous concave design, an appearance shared with the 1961 Thunderbird and the 1961 Lincoln Continental. As with the previous generation, the Montclair was offered in four-door sedan and two-door and four-door hardtop designs. On hardtops, two rooflines were offered, the notchback "Breezeway" configuration (with a reverse-slant retractable rear window) or a fastback "Marauder" configuration; all four-door Montclair pillared sedans had the Breezeway roof. Using a 120-inch wheelbase (one inch longer than Ford sedans), the 1964 Mercury Montclair was equipped with a 390 cubic-inch V8, producing 266 hp. Optional versions of the 390 produced 300 or 330 hp; a 427 cubic-inch V8 was offered with either 410 or 425 hp. The standard engine was offered only with an automatic transmission, with 3 and 4-speed manual transmissions offered as options (the latter, standard on the 427 V8). Fifth generation (1965–1968) For 1965, Mercury introduced a new body and chassis for its full-size sedans, growing to a 123-inch wheelbase;
