Due to customer requests, for 1963 the front seat was redesigned to provide a little more leg room to back seat passengers. The rear deck lid was also raised to provide more trunk space. The floating rectangles in the previous year's grille became a simple matrix of squares.
The car was stretched 3 inches (76 mm) in 1964 to give more rear-seat legroom, and the roofline was squared off at the same time. The dash was also redesigned, doing away with the pod concept. Side glass was now flat to provide more interior room. The gas tank access door, which had been concealed at the rear of the car in the rear grille, was now placed on the driver's side rear quarter panel and the exterior "Continental" script was changed. A 1965 Continental was featured prominently in the American television series Green Acres and the The Matrix Trilogy. The 1965 Continental Convertible is also featured in the opening credits scene of the television show Entourage.
A two-door version was launched in 1966, the first two-door Lincoln since 1960, and the MEL engine was expanded from 430 to 462 in³ (7.0 to 7.6 Ltr). The car was given all-new exterior sheet metal and a new interior. The length was increased by five inches to 220.9, the width by an inch to 79.7, and the height by almost an inch to 55.0 (on the sedan). Sales increased to 54,755 units for the model year, considered a success by Ford. This was a 36% increase over 1965. Product breakdown for the year consisted of 65% sedans, 29% coupes, and just under 6% for the four-door convertible.
The 1970 Continental continued the slab-sided design with blade-like fenders of the previous model, but the suicide doors were gone as was unibody construction. Changes included headlamps which were hidden behind retractable flaps (a characteristic introduced on the Lincoln Continental Mark III), federally-mandated bumpers in 1973, grille changes in 1971 and 1977, and progressive introduction of pollution controls. Nevertheless, from 1972 to 1975 the Lincoln Continental Mark IV successfully fought over the title "King of the Hill" with the Cadillac Eldorado in the personal luxury car category.
