You wouldn’t really think of an '80s era Thunderbird as a "muscle car" necessarily. Coming on its 10th generation in 1988, the Thunderbird had severely worn down its welcome in the market. But before it disappeared forever in 1997 (only to be revived again in 2002), Ford made sure to make it interesting at least one last time with the Thunderbird Super Coupe.
Although the design of the car was pretty bland, Ford was still putting to use its relatively sporty Fox platform underneath. A supercharged 3.8-liter V6 sat under the hood, and pumped out a respectable 210 horsepower. The Super Coupe was so loved by enthusiasts, in fact, that Motor Trend named it the Car of the Year 1989, even though Ford execs lambasted engineers for building such a terrible thing.
