Born from the collaboration between Alfa Romeo and the Zagato coachworks, the Giulietta SZ pushed the twin-cam 1300 berlinetta towards competition: hand-beaten aluminium bodywork, featherweight construction, five-speed gearbox. In 1961-1962, the ultimate evolution appeared, the 'Coda Tronca': a lowered roofline and truncated tail designed according to Kamm's aerodynamic studies, conceived for the high speeds of Monza and Le Mans. Of around 200 SZs produced, only a handful — our example is billed as '1 of 44' — received this bodywork.
Today, the SZ Coda Tronca ranks among the most coveted post-war Alfa Romeos. Each body required some 300 hours of work at Zagato, and the rare surviving examples pass through the major auction houses — RM Sotheby's presented one at Villa d'Este, Gooding & Company offered one at Monterey. Eligible for the finest historic grids, it combines a genuine competition pedigree with absolute rarity, the foundation of enduring collector value.
