The 1956 Ferrari 250 GT Zagato (GTZ) is a highly coveted and successful collaboration between Ferrari and Zagato in car design. It featured a lightweight and aerodynamic body on the proven Ferrari 250 Tour de France chassis. Only a 5 GTZs were made for specific clients, each intended for competition, and some were even customized based on client preferences. Each GTZ had subtle variations, with some made as lightweight as possible. Camillo Luglio, a successful racer, won championships in two different GTZs and declined an offer to join Ferrari's Formula One team. Commissioned by Vladimiro Galluzzi, the 1367GT, known as 'the Prototype,' featured unique elements like the lack of a double-bubble roof and prominent rear fins. Vladimiro quickly replaced it with a disc-brake Scaglietti car, and despite initial sporting hints, the Prototype was sold to a non-sporting owner who never raced it.
