Depending on how old you are, you probably have different recollections of the Mercury Cougar: Baby boomers will likely remember the original V8-powered pony car and its evolutionary change into a big, personal luxury coupe.
Car enthusiasts of a younger vintage are probably more familiar with the Cougar as a small, spry front-wheel-drive sport coupe. About the only common link between all Cougars is their Ford genetics.
Debuting in 1967, the first Mercury Cougar was closely related to the second-generation Mustang. Mercury's version was marketed as being more plush and European. Coupe and convertible versions were offered, and this was the first time that "XR-7" appeared as an option package.
From a performance standpoint, these early Cougars were highly regarded, especially as they could be equipped with a variety of powerful V8 engines.
