5: 1967 Mercury Cougar (Hideous)
We’re not sure what Ford was thinking with the design of the Cougar. A lot of the lines on the car are shared with the Mustang from the same era. While that’s all good, the overall frontal design of the car leaves a lot to be desired. We’re not sure if Ford was going for a luxury car or a performance car, because there is a mixture of both here.
The 390 V8 engine did make up for things in the looks department, but not enough to justify the confused styling of the car. It could be the main reason why the Cougar never attained the same type of popularity the Mustang did.
