Purchased new in 1965 by well-known Alfa enthusiast Hal Chalmers from Knauz Imports in Chicago The car remained in the Chalmers family's devoted care for the next 47 years and 47,000 miles, until Hal Chalmers' son Rex, also a well-noted Alfa authority and long-time AROC Technical Advisor, sold his father's car to his long-time friend Colin Comer, who has owned it since 2012 Runs, drives and feels like only an unrestored Alfa that has been fastidiously maintained since new can This amazing 1965 Alfa Romeo Giulia Sprint Speciale is the only known original-and-unrestored example in existence. As a very late-production Sprint Speciale, it is also the 19th-to-last example of Alfa’s famed show car for the road ever produced. Offered from the renowned Colin Comer Collection, this SS was purchased new in 1965 by well-known Alfa enthusiast Hal Chalmers from Knauz Imports in Chicago. It remained in the Chalmers family’s devoted care for the next 47 years and 47,000 miles, until Hal Chalmers’ son Rex, also a well-noted Alfa authority and long-time AROC Technical Advisor, sold his father’s car to his long-time friend Colin Comer in 2012. To Comer, it was a homecoming of sorts for an old friend, as this very car was the first Sprint Speciale Comer saw as a budding Alfa enthusiast nearly 30 years ago. As every SS aficionado has experienced, it was the arresting beauty of its aerodynamic shape that captured Comer’s imagination. Inspired by the Berlinetta Aerodinamica Tecnica (B.A.T.)—concept cars designed by Bertone’s Franco Scaglione—the SS was introduced in 1957 as a “halo” version of Alfa’s ground-breaking Giulietta. That stylish shape enveloped a truly wonderful GT that, as Comer wrote about the car in “Road & Track” Magazine, “begs to be driven at eight-tenths or better … open the fresh-air vent in the driver’s footwell and let that magnificent Weber induction noise into the cabin, where it'll blend with the ripping-silk exhaust note. It's a feature Alfa unknowingly invented long before cockpit sound tubes became common in modern cars.” A significant part of this Alfa’s charm beyond its breathtaking originality is its unique pairing of Verde Muschio paint and Tobacco interior, a beautiful departure from the traditional Alfa norm of Italian Racing Red. Now showing 50,919 original miles, this 1965 Alfa Romeo Sprint Speciale is the finest example of its breed that runs, drives and performs as one would expect for a car that has been so carefully preserved by very highly-regarded Alfa experts from new.
