The Ferrari that wasn't allowed to be called a Ferrari: the 815 Auto Avio Costruzioni. Yet another model that truly belongs in a Ferrari collection. Before the 125 S (officially recognized as the first Ferrari), Enzo had already built a car that, for legal reasons, could not bear the Ferrari name. There is a fascinating story behind those legal reasons. In the 1930s, Enzo served as team principal for Alfa Romeo under the Scuderia Ferrari banner, until *Il Commendatore* was unceremoniously fired at the end of the decade. Furthermore, he was prohibited from building cars under the Ferrari name for the next four years. Undeterred, Enzo immediately founded Auto Avio Costruzioni (AAC). The company initially manufactured aircraft components, but a twist of fate led Enzo back to automobiles. He was asked by Lotario Rangoni di Machiavelli to build two race cars—for himself and the legendary Alberto Ascari—to compete in the 1940 Brescia Grand Prix. Enzo accepted the challenge, resulting in the Auto Avio Costruzioni Tipo 815, a car designed and built by the boss himself—in just four months, no less. Both Tipo 815s got off to a strong start, taking the lead in the 1,500 cc class. Ultimately, however, Ascari was forced to retire due to technical issues, and the second 815 also had to withdraw with a smoking engine. The car Ascari raced (bearing start number 021) changed hands several times shortly thereafter; it is currently part of Mario Righini's collection.
