RM Sotheby’s has announced the Quadrifoglio Collection for Monterey 2025—a standout group of competition Alfa Romeos from Autodelta’s most iconic era, representing the peak of Italian motorsport and one of the world’s most celebrated marques.
RM Sotheby’s has announced further consignments for Monterey 2025: The Quadrifoglio Collection, a remarkable group of competition Alfa Romeos. Spanning some of Autodelta’s most celebrated works—from the dominant T33/2 ‘Daytona’ to the elegant Giulietta SZ ‘Coda Tronca’—these cars represent the golden era of Italian motorsport and the enduring legacy of one of the world’s most storied marques.
“The Quadrifoglio Collection is a window into a fiercely innovative era of motorsport history,” said Jake O’Gorman, Car Specialist. “These cars were built to compete and to win, and Monterey 2025 is the perfect venue to share them—and offer them to new homes. Alfa Romeo has long been a benchmark of Italian engineering, with deep roots in international motorsport. The models in this collection reflect the brand’s most competitive and technically advanced era, when Autodelta was building race cars to take on the world’s best. From prototypes to touring cars, each example marks a key chapter in Alfa’s evolution on track and in design.”
The collection features twelve Alfa Romeos, with highlights including:
1968 Alfa Romeo T33/2 ‘Daytona’: One of just 10 surviving T33/2s, chassis 015 is believed to be the first factory car fitted with the rare 2.5-liter V-8. With period entries at Daytona, Targa Florio, Nürburgring, and Spa, it was later restored by Autodelta’s Marcello Gambi. Extensively documented, maintained, and raced at Le Mans Classic and Monterey Historics, it’s a thrilling example of Alfa’s prototype legacy (Estimate: $1,700,000 – $2,000,000).
1964 Alfa Romeo Giulia TZ-1 ‘Double Bubble’: The only TZ-1 originally delivered with a double-bubble roof—custom-ordered by Dmitri Nabokov, son of the famed novelist. Raced across Europe and later Australia, it graced the cover of Sports Car World in 1969 and has been under the same collector ownership for 34 years. An unmatched one-of-one with fascinating provenance and racing pedigree (Estimate: $700,00 – $900,000).
1961 Alfa Romeo Giulietta SZ ‘Coda Tronca’: Among just 41 “Coda Tronca” SZs built, this Zagato-bodied lightweight was raced by the Martini & Rossi Racing Team in America’s top events: Daytona, Sebring, Bridgehampton, and Bahamas Speed Week. Restored with correct mechanicals under long-term ownership, it’s a beautifully presented, race-proven piece of Alfa history (Estimate: $400,000 – $500,000).
1970 Alfa Romeo 1750 GTAm: One of only 40 built by Autodelta, this GTAm was delivered to Belgium and believed to have been raced by Alfa Romeo Benelux and later West German driver Franz Abraham. With documented period racing and a preserved, unrestored character, this is a raw, fuel-injected touring car icon—ready for historic competition or collection (Estimate: $200,000 – $250,000).
1966 Alfa Romeo Giulia Sprint GTA: Owned by the same enthusiast since 1986 and restored in the UK shortly after purchase, this alloy-bodied GTA was campaigned in vintage racing and received a full mechanical refresh by SCCA champ Horst Kwech. Well-documented with a replacement engine and restoration records, it embodies Alfa’s alleggerita philosophy: fast, light, and full of character (Estimate: $125,000 – $175,000).
