when the rear window was up, the airflow would be used to keep the rear window clear in inclement weather. The Colony Park underwent two exterior revisions, in 1967 and 1968, following Lincoln Continental styling updates; redesigns were made to the simulated wood paneling, where the entire side of the body was covered and eliminated the tapered appearance on the front fender. For 1967 and 1968, the Mercury Park Lane coupe and convertible featured the same simulated wood paneling as the Colony Park as an option package. Called "yacht deck paneling" by Mercury, the option was rarely ordered and was discontinued as the Park Lane was replaced by the Mercury Marquis. For 1965, the 390 V8 was the sole engine. In 1966, Mercury added two additional FE V8s, a 330 hp 410 "Marauder" V8 and a 345 hp 428 "Super Marauder" V8. For 1968, the 410 was dropped, replaced by a 315 hp version of the 390 V8. Sales Fifth generation (1969–1978) Alongside a redesign for the 1969 model year, Ford integrated its station wagon product lines of both Ford and Mercury brands within the nameplates of their sedan counterparts. For the Colony Park, this change made it part of the Mercury Marquis model line. In contrast to the Marquis sedan, the Colony Park was based on the wheelbase of the Ford Country Squire and the Ford LTD, and only the Colony Park had concealed headlight covers and the simulated woodgrain body panels, while the Monterey station wagon, which was very similar, did not. This was done to position the Colony Park and Marquis as visually similar to the 1969 Lincoln Continental and the Mark III. The 1969 Colony Park was listed at US$4,457 ($ in dollars) and 25,604 were made. The Colony Park and Monterey station wagons were the senior level vehicles to the slightly shorter Mercury Montego station wagons which did also offer the simulated woodgrain appearance. This generation introduced covered headlights, which were deployed using a vacuum canister system that kept the doors down when a vacuum condition existed in the lines, provided by the engine when it was running. If a loss of vacuum occurred, the doors would retract up so that the headlights were usable if the system should fail. The Magic Doorgate was reworked so that it could swing outward like a conventional door without having to roll the window down, while the glass
