Offered From a Private Collection

1967 Ferrari 275 GTB/4 by Scaglietti – This largely original and well-preserved example, presented in its original colour combination, has had just four dedicated caretakers from new, including 45 years of single-family ownership. It is the 203rd of 330 examples built, is documented with SEFAC invoice and correspondence, service/restoration invoices dating back to 1967, former owner’s mail, and history by Marcel Massini, and offers the potential for Concours presentation or touring enjoyment (Estimate: $3,000,000 – $3,500,000).

1971 Lamborghini Miura P400 SV by Bertone – One of 150 SV examples built and wearing a colour combination of Blu Notte over light grey, this Miura is desirably equipped with air conditioning and a split-sump lubrication system. Reportedly fully restored by Bobileff Motorcar Company, including an engine rebuild by the noted Bob Wallace, it was presented at Concorso Italiano, La Bella Macchina, and the Lamborghini Club of America National Meet. This P400 SV is a rare example of the most highly developed Miura (Estimate: $3,000,000 – $3,500,000).

1966 Ferrari 500 Superfast Series II by Pininfarina – One of just 12 second-series examples and 36 total examples built, the legendary West Coast sports car importer and racing impresario John Von Neumann originally owned this Superfast. It was comprehensively restored in 2006 by the respected Paul Russell and Co. It is equipped with a rare and powerful Tipo 208 engine that combines the best of the Lampredi and Colombo engine genealogies. Boasting a colour combination of dark blue paint over cognac leather, it has been awarded at prestigious events, including the Amelia Island Concours d’Elegance, Pebble Beach Concours d’Elegance, and the Cavallino Classic. It would make a stunning addition to any collection (Estimate: $2,200,000 – $2,800,000).

1997 Porsche 911 Turbo S – One of 183 produced for North America in 1997, this Porsche is the final and most technologically advanced air-cooled 911 Turbo. Finished in Ocean Blue Metallic over Cashmere Beige with deviating Midnight Blue leather, this 911 shows just 22,017 miles at the time of cataloguing (Estimate: $550,000 – $650,000).

1958 BMW 501-8 – Restored to Concours condition by marque experts in the late 2000s, this 501-8 is a rare example of BMW’s first post-war creation from the final year of production and presents the timeless BMW design—the “baroque angel”—with V-8 power. Attractively finished in silver over blue leather, it boasts a Becker Mexico radio, VDO outside temperature thermometer, and a Golde sliding canvas sunroof (Estimate: $90,000 – $100,000).
