Finally, we look at a true American giant. This Imperial was built like a tank, though somehow it was referred to in its day as a sports coupe.
It originally sold for about $6,011, and Leno recalls that the size was always the car's major talking point.
"These were so overbuilt," he says. "When I was a kid, they used to have demolition derbies. And if you showed up with an Imperial, nine times out of 10 you'd be banned because you had an unfair advantage."
This one is more or less well maintained. It was previously owned by a movie producer who loved it dearly. The only restoration has been retouched paint from time due to scratches and fender benders. Otherwise, the tank is still original.
So which one of these untouched classics appreciates best? Watch the video to find out.
