11. Morgan Plus 8 Propane
Complex Says: Morgan is one of the coolest car companies of all time. These cars are made with ash frames, along with styling that hasn't been updated for so long that it is the main selling point. We call it driving now, but Morgan still calls it motoring. However, in 1975 emissions requirements forced Morgan out of the US market. A man named Bill Fink figured out a way to run the Plus 8's V8 on propane to allow it to be sold in the US. This dropped the horsepower from 190 to 150 and meant that there was a propane tank bolted to the back of the car.
