26: 2000 Mercury Cougar
The 2000 Mercury Cougar was built in an attempt to bring new life to the Mercury lineup. For all of the 1980s and 1990s, the Mercury lineup was nothing more than a showcase for rebadged Ford models. The Cougar was its own unique car from the styling to the marketing and it was initially a hit. The problem was its build quality and lack of performance that disappointed drivers once they got behind the wheel (via Car Gurus).
The Cougar was always a V8-powered rear-wheel drive car but now it was sort of the domestic version of the Hyundai Tiburon. The build quality of the car wasn’t great either and there were complaints about the transmission. The Cougar didn’t stay on the market long and by 2004 it was discontinued. The car had a lot of promise, but a lack of build quality just made the Cougar doomed from the start and Ford discontinued Mercury not long afterward.
