This model was both the fastest and most expensive production car for sale in 1967. Just 18 models were produced from 1967 - 1969, and today the value of surviving models is in excess of $10 million. It was the first car to ever feature butterfly doors.

This is the Alfa Romeo 33 Stradale, based on the Tipo 33 racing car produced around the same time.
