Built in an attempt by Alfa to make some of its racing technology available to the public, it was the most expensive automobile for sale to the public in 1968 at US$17,000.
In the same year, in Italy, the retail price for a 33 Stradale was 9,750,000 lire. Just to make a comparison, the Lamborghini Miura was sold for 7,700,000 lire, while the average worker's wage was about 150.000 lire.
The Alfa Romeo 33 Stradale are hardly ever traded; thus their value is very hard to estimate. At the 2015 Detroit Auto Show, while presenting the Alfa 4C Spider, Alfa's Head of North America estimated the current market value of the 33 Stradale at "well over $10 million".
