6. 1954 Oldsmobile F-88 GM Concept Car
The Oldsmobile F-88 is thought by many to be one of the most influential ever made, and it’s now one of the rarest too.It was designed as a dream car in 1954, and was a project of love by American designer Harley Earl, based on designs by Bill Lange. It was built around the chassis of a Chevrolet Corvette, and had a body made entirely out of fiberglass.
The two door roadsters had a super 88 V8 engine which produced 250 brake horsepower, and the style of design was the first of a new era of car aesthetics and the one that led the way.
Despite this, only four were ever made. Two became part of private collections and their whereabouts are unknown, one was destroyed in a fire, and the final car was used as a show car.
It was sold at the Barrett-Jackson collector car auction in 2005 for three million dollars, and is now permanently on display, for anyone to see, at the Gateway Colorado automobile museum.
