20: Ford Mustang II
Ford’s Pinto-based Mustang II was a gamble from the start. Taking a legendary icon and shrinking it down was questionable at best. The Mustang II was vastly underpowered and the exterior styling was a far cry from the original brand. There was a special Cobra edition but for the most part, the Mustang II was a joke when you compared it to the previous generation car (via Motor Trend).
The controversy surrounding the Pinto this time was enough to stop the Mustang II in its tracks. The car just couldn’t overcome the reputation of its humble economy car-based roots and live up to the prior reputation that the Mustang brand had built up.
