Originally a derivative of the Country Squire and Edsel Bermuda in 1958, the later Colony Park station wagons were based on the Mercury Grand Marquis, which itself was a luxury version of the Ford Crown Victoria.
There were six generations of the Colony Park. The first was from 1957 to 1959 and based off the Bermuda and Lincoln Continental, the second was from 1960 to 1964 and based off the Mercury Monterey, Ford Galaxie, and Lincoln Continental, the third from 1965 to 1968 was also based off those cars as well as the Ford LTD and Mercury Marquis, the fourth was from 1969 to 1972, the fifth from 1973 to 1978, and the final sixth generation Colony Park was from 1979 to 1993.
As would be expected from a car this size, they were V8 engine cars. The final generation got a V8 that made a paltry 150 horsepower. It was based on the Panther platform and got a 4 speed automatic engine.
