Built by Giotto Bizzarrini, designer of the Ferrari 250 GTO which is now arguably the most valuable collector car in the world, the 1966 Bizzarrini GT Strada 5300 is another top collectible. The Bizzarrini was built as a street legal Grifo A3C. In 1965, a Bizzarrini Grifo won its class at Le Mans and finished ninth overall. 133 Bizzarrini Stradas were made and about 80 still exist today.
