Each situation is different, and provenance often plays an important role in the high value of these cars, as do production volumes. For example, the 1966 Ferrari 330 GT 2+2 Series II that sold for $182,000 is one of only 36 righthand-drive models ever made, and it was optioned with power windows, a rare feature for the time. In the case of the 1956 Ferrari 250 GT Coupe Speciale produced by Pininfarina, the hammer fell at $1.65 million because it is one of just four bodied by the Italian design house in 1956. In addition, it had a prominent owner, having been originally ordered by King Mohammed V of Morocco.
More important than all of these factors is that each of these classic Ferraris retain their original matching-numbers engines and gearboxes, and besides the damage done by the passage of time, the cars are effectively made up of exactly the same parts that they left Maranello with several decades ago.
They also have that original chassis number, which means even if the cars are completely rebuilt, so long as it’s handled by an official restorer under the auspices of the Ferrari Classiche department, it will always be classified as that original chassis.
