2: Ford Excursion
The 2000s were a trying time at the Ford Motor Company, and as the SUV market was expanding the company decided to launch a large SUV to compete with the Suburban. The Excursion was a V10-powered beast of an SUV that offered a great deal of performance but was terrible on gas mileage (via Hot Cars).

The Excursion could have been a big hit for the Ford Motor Company but the SUV didn’t manage to sell well. The reliability was questionable, and the design on the thing wasn’t the most pleasant to look at. The Excursion’s off-road capability has made it popular on the used car market although the sales were not very impressive when the Excursion was being sold as a new vehicle.
