6: Lincoln Continental
The new Continental was released to much fanfare in 2017 complete with a heavy advertising campaign featuring actor Matthew McConaughey. Sadly, the result was a car that made big promises but fell flat on its face. The first glaring problem with the Continental was the lack of a V8 powerplant (via Motor Biscuit).
Traditional buyers were looking forward to a rear-wheel-drive V8-powered full-size sedan once again. The Continential had a lot going for it but the lack of some fundamental features that traditional Lincoln buyers were looking for left it in the lurch this time around.
