5: Mercury Cougar
The early 2000s Mercury Cougar was sort of a last-ditch effort for Ford to revitalize the Mercury brand. The car had everything going for it, including the styling. But it lacked in the performance department, which let a lot of buyers down. The styling was also on the feminine side, which was done on purpose by Ford (via Cars.com).
The problem is that the original buyers of the Cougar were alienated and the car stopped selling. The new age Cougar went on for a few years before cutting the car off altogether. Eventually, the Mercury brand was disbanded, and the Cougar is now a thing of the past. But you can still find one for a low price and enjoy its nostalgia.
