COU meaning in General ?

Mercury Cougar is a nameplate applied to a diverse series of automobiles sold by the Mercury division of Ford from 1967 to 1997 and from 1999 to 2002. While the nameplate is most commonly associated with two-door coupes, at various times during its production, the Cougar was also marketed as a convertible, four-door sedan, station wagon, and hatchback.

With 2,972,784 examples produced, the Cougar is the highest-selling nameplate ever produced by the Mercury brand; its 34-year production is second only to the Grand Marquis in the Mercury model line (produced for 36 years). During the 1970s and 1980s, the Cougar was closely tied to the marketing of the Mercury division; Mercury advertised its dealers as "The Sign of the Cat" with big cats atop Lincoln-Mercury dealer signs. In line with the Cougar, several animal-related nameplates were adopted by the division, including the Bobcat, Lynx, and Sable.

During its production, the Cougar was assembled at the Dearborn Assembly Plant (part of the Ford River Rouge Complex) in Dearborn, Michigan from 1967 to 1973, San Jose Assembly (Milpitas, California) from 1968 into early 1969, Lorain Assembly (Lorain, Ohio) from 1974 to 1997, and at Flat Rock Assembly (Flat Rock, Michigan) from 1999 to 2002.
