12: Cortina
Another cheap car that made the rounds in the Ford lineup was the Cortina. It was a car that needs no introduction because you’ve probably forgotten it anyway. Why did the Cortina fail? Well, the design was lackluster at best. Reliability was not a strong suit for the car, and the performance was nonexistent. There were very few features that you could get on this car and it was barebones transportation.

The Cortina had a lot of what compact car consumers were looking for, but the lack of the car delayed a lot of the potential consumers. Few cars have failed as badly as the Cortina managed to in the short period that it was released.
