41. Panther 6
Almost forgotten today, Panther Westwinds was a British car company that concentrated on retro-styled roadsters and custom cars. During the 1970s, Panther became famous for its popular De Ville Roadster and a series of wild one-off creations that captivated the imagination of car fans all over the world. However, one of the craziest cars they produced in that period was the Panther 6. It was a six-wheel roadster with a monstrous 8.2-liter-V8 engine they sourced from the Cadillac Eldorado. They placed an enormous engine behind the cabin to power the rear wheels, while the four wheels in the front managed the steering.

To achieve the proper ride height and save space in the front where the double suspension assembly was, they installed smaller wheels compared to the bigger ones in the back. Westwinds conceived the Panther 6 as an over-the-top luxury convertible. So, they gave it a leather interior, climate control, and power windows and doors. They even installed a TV and phone. The designers claimed the Panther 6 could achieve 200 mph or 320 km/h top speeds, but the automobile experts were suspicious of these numbers. On top of that, Panther never allowed anyone to do independent testing. In production between 1977 and 1978, Panther produced just two vehicles in this model. Both cars still survive to this day.
