For 1964, Mercury revised its sedan offerings; while the S-55 was discontinued, the Montclair and Park Lane made their return. In another change, the Marauder fastback was introduced as a four-door hardtop (giving Mercury a second roofline distinct from Ford); while performance-oriented, all three Mercury sedans offered the Marauder roofline as an option. In line with the Ford Thunderbird, the entire front fascia became more convex, with a more closely-fitting front bumper. Coinciding with the Montclair and Park Lane, the Monterey was reintroduced as a two-door sedan; the four-door hardtop was only offered as a Marauder fastback.
