19. Hummer H1
Back in the mid-80s, the U.S. Military started using the High Mobility Multipurpose Wheeled Vehicle or HMMWV, affectionately known as the Humvee. This was a big, heavy military truck capable of running over anything, including landmines. Even though the strictly built and engineered the Humvee for the military, constant requests for a street-legal version made AM General think about entering the lucrative civilian market. Finally, in 1992, they presented a civilian Hummer H1.

It looked almost the same as the military version featuring the same technology and engine. Power came from a 6.2-liter diesel V8 with just 165 HP, but it had loads of torque. Basically, the only real difference between the military and civilian Hummer was the interior. In fact, the street-legal model had a much plusher interior with air conditioning, leather upholstery and a premium audio system. However, the Hummer H1 was expensive and terrible to drive. And it was impractical since it was as big as a house. However, it was extremely popular with those customers who wanted something different and opulent, but who didn’t pay attention to practicality and fuel economy.
