In 1959, Ferrari created a unique one-off version of the 400 Superamerica, designated s/n 1517SA, specifically for Gianni Agnelli. This car holds the distinction of being the very first of the 400 Superamericas. Its design, particularly the characteristic square grille, was notably similar to that of the Maserati 5000 GT, another exclusive vehicle built for Agnelli. This model highlights the bespoke nature of Ferrari's approach to car design for high-profile clients.
