3. Hummer H2
The Hummer H2 had the misfortune to just be the wrong automobile for the time. The H2 is loud, appears to burn gasoline while the owner just looks at his or her keys, and was released not too long after the terrorist attacks against the United States on 9/11. The H2 never quite gained the popularity that the manufacturer envisioned by releasing the automobile in a country at war, and the vehicle never quite picked up in popularity abroad. In Great Britain, the H2 was actually one of the lowest selling vehicles of all time primarily due to its very poor fuel economy. Still found on the roadways today, the H2 never quite lived up to the hype and was a big disappointment to car fans.
