3. 1980 Mercury Capri RS
The introduction of the third-generation Mustang had a big influence on Mercury. This is because the brand got its own version in the form of the Capri in 1979. But from 1970 to 1977, Mercury sold the Capri. It was a model they imported from Germany with four and six-cylinder engines.
However, in 1979, thanks to the Mustang, the Capri was new and featured a unique front-end design. Since it was a Mercury product, it was more upscale than Ford. But other than a few aesthetical changes, it was identical to the Mustang. As the performance version, Mercury introduced the RS model featuring a 2.3-liter turbocharged engine delivering just 135 HP. Performance was expectedly bad, but the car looked cool with a big air intake on the hood, RS badges, and a rear spoiler. Today, those RS models are quite rare although not that valuable or sought-after by car collectors.
