The car that established Alfa Romeo in the 1.3-litre performance class — from Bertone Sprint to Zagato SZ.
The Giulietta Sprint was the first Giulietta model introduced — at the 1954 Turin Motor Show — and the car that established Alfa Romeo in the 1.3-litre performance class. All variants share the 1,290 cc DOHC inline-four (designed by Giuseppe Busso) in different states of tune.
The Sprint Normale and Sprint Veloce were built at Bertone's Grugliasco plant; the Sprint Speciale at Portello; the SZ by Zagato in Milan. The Sprint Veloce introduced plexiglass sliding side windows and weight reductions bringing the car to 780 kg. The Sprint Speciale was Franco Scaglione's aerodynamic masterpiece — a drag coefficient of 0.29 Cd, making it the world's fastest 1.3-litre production car at 200 km/h.
The Sprint Zagato originated when Elio Zagato reclothed a crashed Sprint Veloce for the Leto di Priolo brothers after the 1956 Mille Miglia; the resulting SVZ's competition success led to the production SZ from 1960. From 1954 to 1965, 177,690 Giuliettas were produced in all body styles.
The SZ Coda Tronca is among the most valuable Giuliettas; the Sprint Veloce Alleggerita and early Sprint Normale with full documentation are rising steadily; the Sprint Speciale remains undervalued relative to its rarity and design significance.

Authenticate stamped chassis and engine numbers against factory or club records. For the Giulietta Sprint family specifically, verify assembly plant against variant (Grugliasco / Portello / Zagato Milan), confirm the correct Tipo 00120 engine and 4- or 5-speed transmission for the variant, and distinguish SZ Coda Tonda from SZ2 Coda Tronca and from the earlier SVZ competition cars.
Confirm body originality, panel identity and restoration standard against a marque specialist.
Confirm continuous service history and any rebuild history for the engine, transmission and driveline against a marque specialist.
Restoration standard, originality of body and driveline, and any documented ownership record are the main value drivers.
