wood-grained Mercury Colony Park was sold with four doors only. To distinguish itself from Ford (and Edsel), all Mercury station wagons were given hardtop rooflines. Marketed as the flagship of the Mercury station wagon model line, the Colony Park was trimmed and shared a chassis with the similar Mercury Turnpike Cruiser, positioned above the Monterey. The 1957 Colony Park also offered a rear window that retracted into the tailgate, which was not offered on Ford-branded station wagons until 1961. The interior featured several comfort and convenience features, like an electric clock, vinyl upholstery, full passenger compartment carpeting, chrome window surround moldings, rear side vent windows, and simulated mahogany grain vinyl body side trim with simulated maple trim panels as standard features, while a padded dash was optional. The Colony Park was listed with a retail price of US$3,677 ($ in dollars ) and 7,386 were manufactured. Sharing its powertrain with the Montclair and the Turnpike Cruiser, the 1957 Colony Park was fitted with a 368 cubic-inch Lincoln Y-Block V8. For 1958, the Y-block was replaced by two "MEL" V8s. The standard engine was a 383 cubic-inch V8, with a 430 cubic-inch V8 available as an option; a "Super Marauder" triple two-barrel carburetor option for the 430 was the first American mass production engine rated at 400 hp. For 1957, Mercury offered mechanically activated pushbutton transmission controls in response to the Chrysler TorqueFlite pushbutton controls introduced in 1956. The Mercury control buttons initially offered five buttons and was called "Keyboard Control", with a long button on top labeled "Drive" and four smaller buttons below labeled "Brake"; "Neutral Start", which would allow the engine to start with the ignition key; "Hill Control" and "Reverse", with later versions separating the "Drive" button to "Performance" and "Cruising" for 1958 and relabeled as "Multi-Drive". A separate push/pull lever was included below the control buttons labeled "Park", which would lock out the control buttons until the Park button was pulled to release it. The control panel was located to the left of the steering wheel. All Mercury station wagons were produced with hardtop rooflines, while Ford station wagons did not offer that body style feature. The standard equipment offered on the Colony Park included cloth and vinyl upholstery, fully carpeted floors, electric clock, chrome window surround moldings, full length bodyside stainless steel trim, wheel openings and rocker panel molding, lower rear quarter trim, power steering, power
