14: 1974 to 1978 Ford Mustang II
What happens when a company tries to turn an economy car into a performance car? You get the Mustang II. This is perhaps the most infamous Mustang because it was launched right on the heels of the fuel embargo. The Ford Mustang II was universally panned by drivers and the automotive press alike because of its paltry design. The power of this Mustang was downright puny and the car looked just like a Pinto as there was nothing unique.
Although the Pinto-based Mustang was one of the worst-selling models of all time for the brand, they have since become a collector’s item. These tiny Mustangs are highly sought after as a novelty item and something drivers throw a larger engine into. Coyote swaps seem to be the going thing for the Mustang II, which is unique, to say the least.
