Not every great collection makes itself known. Some of the most consequential automotive transactions in the world unfold quietly, far from crowded salerooms and the theatre of public bidding, conducted instead in the measured register that discerning collectors have long preferred.
This is the ethos behind RM Sotheby's Sealed Auction series. A carefully curated group of lots, each extraordinary in its own way, is presented in an exclusive and discreet format, with bidding opening on 13th May and final rounds closing on 20th and 21st May 2026.
Three automobiles anchor this edition: one each from Ferrari, Maserati, and Porsche, three marques whose enduring rivalry has helped define automotive history, and whose most exceptional examples remain the most arresting objects in any serious collection.
2004 Ferrari Enzo
There exists a brief and very particular lineage of cars that redefined what it meant to own a Ferrari. The 288 GTO, the F40 and the F50 arrived as an unambiguous statement from Maranello that the road car could be driven to the very boundary of the possible. When the Enzo made its debut at the 2002 Paris Motor Show, it delivered that same declaration with renewed force: a car conceived around Formula 1 engineering principles, clothed in a body penned by Ken Okuyama at Pininfarina, and propelled by a 6.0-litre V-12 that stands as the last naturally aspirated, non-hybrid V-12 hypercar engine Ferrari has ever made.
Only 399 examples were produced, with the presented example being among the most conscientiously preserved. Completed in February 2004 and finished in Rosso Corsa over Nero, its original specification maintained without deviation to this day, this Enzo passed its formative years with a German owner who used it with genuine purpose: track days at the Nürburgring, the Ferrari Tribute to the Mille Miglia, the Alpen-Corso in Feusisberg. Ferrari Classiche certification, granted in May 2025, confirms the continued originality of the chassis, engine, gearbox, and bodywork. A comprehensive service exceeding €30,000 followed, alongside a 190-point inspection carried out at Munsterhuis Sportscars in February 2026. The odometer reads just under 7,200 kilometres from new.
More than two decades on, the Enzo bridges the analogue and digital ages with the assurance of something that never had to choose between them. Estimated at $ 7,411,730 – $ 8,117,609, this ranks among the finest examples available anywhere in the world.
1954 Maserati A6G/54 2000 Spyder Zagato
There are rare cars, and then there are cars that occupy an entirely different order of rarity. Chassis number 2101 belongs to the latter. It is the sole open-bodied example ever constructed on the A6G/54 platform, the prototype for the entire Zagato-bodied series, and the first car to receive the model's twin-cam engine. Originally commissioned by Argentine president Juan Perón, it was exhibited at the 1955 Geneva Salon and the 1956 Paris Salon before returning to the Pebble Beach Concours d'Elegance in August 2024, where it claimed both its class victory and the Jules Heumann Most Elegant Open Car award, the two highest distinctions available short of Best of Show itself.
The 1950s represented a singular moment in which hand-built coachwork and sculptural design converged at their absolute zenith. It was the decade of the Mercedes-Benz Uhlenhaut Coupé and the ex-Rossellini Ferrari 375 MM. Chassis 2101 belongs in that company without reservation. Its provenance reads accordingly: ordered for a head of state who was overthrown before delivery, displayed twice on the international show circuit, acquired by an American diplomat in Paris, driven to Le Mans in 1959, transported across the Atlantic, and held in storage for roughly three decades, emerging with a remarkable degree of originality still intact.
A thorough 2024 restoration by Fast Cars Ltd of Redondo Beach addressed every element of the chassis, including the first-ever rebuild of the matching-numbers transmission. Marque authority Adolfo Orsi's exhaustive historical report confirms the presence of the matching-numbers engine. The outcome was a car that arrived at Pebble Beach and claimed two of its most celebrated honours. Accompanied by factory production records, build sheet copies, the original owner's manual, and an irreplaceable original tool roll, this is a car for which the phrase "once in a generation" is simply accurate. Offered at an estimate available upon request, which in itself conveys something.
1991 Porsche 911 Reimagined by Singer - Classic Services - The Four Seas Commission
Singer Vehicle Design requires little introduction to anyone who moves seriously within collector car circles. What the Californian atelier has accomplished by taking the air-cooled 911 as its starting point and reimagining it with a standard of craft that invites comparison with the finest Swiss horology has yielded some of the most sought-after modern collector cars in existence. The Classic Services programme, now closed, represented Singer's most complete realisation of that vision, and the Four Seas Commission stands among its most distinguished results.
Completed in February 2023, the Four Seas Commission was conceived around performance, material integrity, and real-world usability in equal measure. At its heart is the 'Motorsports' specification 4.0-litre engine developed in collaboration with Porsche Motorsports North America, featuring a revised crankshaft, Porsche Motorsport oil pump, and refined valve specifications; it is the highest-output engine offered across the entire Classic Services range. Drive reaches all four wheels via a six-speed manual gearbox, with Öhlins adjustable suspension and Brembo carbon ceramic brakes completing the mechanical picture.
Visually, paint-to-sample Nato Green over Singer's carbon fibre bodywork, complemented by nickel-finished bumperettes and RS wheel centres, achieves something quietly and assuredly spectacular. Within, Monument Valley leather, Torre Colombara detailing, carbon fibre bucket seats, a satin mahogany gearshift knob, and early 911 instruments finished in Nato Green with orange needles compose a cabin that is at once period-faithful and thoroughly contemporary. Porsche Classic Navigation with Apple CarPlay ensures that usability was never sacrificed in the pursuit of purity.
Having covered just 250 kilometres since recommissioning and presented in virtually as-delivered condition, the Four Seas Commission offers a rare opportunity to acquire a Singer Classic Services 911 at the very outset of its life as a collector's piece. Estimated at $1,300,000–$1,500,000, it will not remain available for long.
