8: Lincoln Blackwood
You’ve got to at least give Ford credit for trying new things and the company did just that with the Lincoln Blackwood. This was probably the first authentic luxury pickup truck from a domestic automaker, a unique feat. The problem is that consumers want more than just a unique nameplate and the Blackwood just failed to deliver on a lot of fronts (via Motor Trend).
The truckbed was utterly useless at a time when consumers were using pickup trucks more than ever before. The Blackwood was more of a novelty item than a useful vehicle and this is partly the reason that the truck faded into obscurity after one year.
