Rolls-Royce 15 HP
Fifteen horsepower may not seem much today, but back when this model was manufactured, it was a lot. This unit was built in 1904 and is actually the first-ever Rolls Royce model ever created. Only six units of this model were ever created. Insurance companies value each of these cars at around thirty-five million dollars each. This is not because of the functionality, but purely for sentimentality and rarity. As the first-ever Rolls Royce units, these rightfully cost a fortune each.
