chassis. Now sharing its roofline with the Ford Country Squire, the Colony Park moved from sharing its interior trim from the Montclair to the Monterey. Though the 1961 redesign of the Mercury product line was not intended as downsizing, the transition between the model years marked a significant decrease in exterior dimensions. From 1960 to 1961, the Mercury Colony Park shed approximately five inches in length, six inches in wheelbase, and approximately 500 pounds of curb weight. The Colony Park remained the luxury level Mercury vehicle, with many optional items included with the listed retail price of US$3,118 ($ in dollars ) and selling 7,887 examples. In place of the 430 MEL V8, Mercury fitted the Colony Park with three separate V8 engines. A 292 Y-Block V8 was the standard engine for 1961 and 1962, with 352 and 390 FE V8s as options. In 1963, the 390 became the standard engine. For the first time, 3- and 4-speed manual transmissions were offered in the Colony Park, with the 3-speed Merc-O-Matic as an option. Sales Fourth generation (1965–1968) For 1965, Ford redesigned its entire full-size sedan and station wagon product line, including the Mercury Colony Park, and was once again separated as its own model line with the mid-level Commuter without the simulated mahogany wood trim. While retaining a body-on-frame chassis, the leaf-spring rear suspension was replaced by a coil-spring live rear axle configuration; through several design changes, the basic layout would be retained through the final Crown Victoria, produced in 2011. While the Colony Park retained its roofline alongside the Ford Country Squire, it adopted the slab-sided design language taken on by Mercury sedans, heavily influenced by the exterior of the Lincoln Continental. The 1965 version was listed at US$3,364 ($ in dollars ) and 4,213 were manufactured. Through this generation, Mercury would make several design changes. For 1966, the rear tailgate was updated, marking the debut of the two-way "Magic Doorgate" shared with all other Ford and Mercury station wagons; the design allowed the tailgate to fold down as a tailgate as well as swing out to the driver's side as a door. For 1967, passenger capacity was expanded, as sideways-facing third-row seats were added as an option. To increase ventilation for the rear of the vehicle, the Colony Park introduced fresh-air ventilation through channels integrated into the D pillar, allowing ventilation if the rear window was retracted, and
