Near the end of the story, Milo takes Enzo for a ride in a replica 1957 Ferrari 250 Testa Rossa. Only 33 original Testa Rossas were made, from 1957 to 1961, and they are highly prized for their racing success at the hands of legendary drivers. In 2014, an original 1957 Testa Rossa sold privately for $39.8 million.
