4: Cadillac Coupe DeVille
What’s known as one of the last massive luxury cars, the ’70s Coupe DeVille was the epiphany of luxury. The styling of the car was big and bold at a time when these things were the norm for cars. The fuel crisis of the 1970s made the car less popular, because it was a gas guzzler, and ultimately GM had to downsize (via Notorious Luxury).
But among collectors, the Coupe DeVille has held a solid position in the market. In recent years, these cars are becoming harder to come by, and the styling as iconic as you can get. There will never be a car like this one again and that makes the Coupe DeVille even more enticing.
