2. Lincoln Blackwood
Back in the early 2000s, Lincoln found success with the Navigator, the golden standard of luxury SUVs at the time. Wanting to capitalize on that success, somebody at Lincoln suggested building a pickup version and expanding the range. The idea seemed pretty plausible and soon their prototypes were sent to testing. The Lincoln used a Ford F-150 platform with the front end and cabin of the Navigator, but a custom truck bed that opened like doors and even had a power cover (via Motor Trend).
The finished product looked like a Navigator truck and it was luxurious. But it failed as a truck since the bed was very small and unusable. The biggest problem was the price, as the brand-new 2002 Lincoln Blackwood started at a whopping $52,000, an extremely high price for an unusable truck with Navigator fascia. As you could expect, the market was not amused. During its 15 months in production, only 3,356 were made.
