For 1967, the roofline of four-door sedans underwent a minor revision, adopting a more formal C-pillar profile; the reverse-slant Breezeway roof was discontinued (an optional retractable rear window remained available, using the standard roofline). For a third time, the taillamps were redesigned, spanning from the top of the fender to the bottom of the bumper. Largely overshadowed by the smaller Cougar, the S-55 became an option package for full-size Mercury two-doors.
