4. 1954 Oldsmobile F-88 – $3.5 million
Even if there had been heaps of 1954 Oldsmobile F-88 models, the collectors would still pay attention to this vehicle. However, only four F-88 cars came out of the factory, and it comes to no surprise to learn that this model sells for $3.5 million today. Under its hood is a V8 rocket engine good for 250 horsepower which only increases the price.
