Sealed Bids: Rare Porsche, Maserati and Supercars For Sale
Collecting Cars launches its November Sealed Bids online car auction with a 1990 Porsche 962C Group C racer and the first long-wheelbase Porsche 911 E prototype built by the factory as star attractions. A 1962 Maserati 5000 GT, commissioned initially by Mexican President Adolfo López Mateos, a 2022 Lamborghini Countach LPI 800-4, and a McLaren 675LT Spider MSO Carbon Series, showing only 23 kilometres from new, complete the headline lineup. All cars are open for online sealed bidding today, Thursday, 6 November, with auctions closing on Thursday, 13 November, providing collectors worldwide with a private, digital route to secure rare performance and classic cars.
The November Sealed Bids sale features one of the most original factory-built Porsche endurance racers ever offered for sale. Porsche built chassis 962-163 in July 1990 for Brun Motorsport as one of just seven customer 962Cs to full 1988 works specification and one of only three delivered new to the team. It has an accident-free, unrestored history, with only two period outings at Montreal and Mexico City. The car retains its factory bodywork, hand-painted Repsol livery and correct 3.0-litre twin-turbocharged flat-six engine, which produces around 700 bhp, and it still presents as a highly authentic Group C Porsche 962C. After decades in prominent private collections, Katana Ltd sympathetically recommissioned the car in 2023, preserving originality while ensuring track-ready performance. Collecting Cars utilises its Sealed Bids format and global community of bidders to offer this Porsche 962C for sale this month through its online platform, providing serious endurance racing collectors with a rare opportunity.
The 1968 Porsche 911 E prototype, chassis 119200001, carries equal significance within the Sealed Bids auction. Collectors now see, for what is understood as the first time in public, this factory-documented "Versuch" prototype, confirmed as the very first long-wheelbase 911 E built. The car features the first Bosch mechanical fuel injection engine for the 911 and the first magnesium crankcase for a road-going 911 model, marking a crucial step in Porsche 911 development. Porsche originally constructed it as prototype chassis 320012 before renumbering it, and the car bridges the transition between short- and long-wheelbase production. It also stands as the only known 911 on record to receive a complete factory conversion from left-hand drive to right-hand drive. Its provenance includes ownership by racing driver Robs Lamplough, F1 business figure Paddy McNally and works driver and two-time Le Mans class winner Jo Siffert. After more than 25 years off the road, leading UK specialists completed a £280,000 restoration, retaining its matching-numbers engine and gearbox so that this Porsche 911 E prototype combines documented history with exceptional presentation.
Among other highlights, the Sealed Bids event includes a 1962 Maserati 5000 GT by Allemano, chassis 103.042, which Maserati built for Adolfo López Mateos during his presidency of Mexico, as one of only 34 examples ever produced. A passionate Maserati enthusiast, he remains the only person on record to have owned two 5000 GTs. This example boasts a remarkable backstory, including service with the Mexican police before it resurfaced in the United States, where recognised Maserati specialists Jerry Wood and Keith Duly handled the car. A concours-quality restoration, completed in 2024, returns it to its original Grigio Montebello with a blue Connolly leather interior, featuring a freshly rebuilt engine and gearbox. It presents one of the finest Maserati 5000 GTs available in any online auction.
Collecting Cars also presents a 2022 Lamborghini Countach LPI 800-4 in the same Sealed Bids sale to showcase modern Italian supercar engineering. Lamborghini built only 112 examples, each combining a hybrid V12 powertrain with 803 bhp and a top speed of 221 mph. The car on offer is an original UK-supplied example in Rosso Scintilla, recently serviced at Lamborghini Edinburgh and showing 6,526 miles. It offers buyers a rare opportunity to secure one of the most significant and collectable modern Lamborghini Countach models through a discreet sealed-bid format.
Completing the lineup, a McLaren 675LT Spider MSO Carbon Series joins the November Sealed Bids catalogue as one of the most exclusive modern McLarens. McLaren built just 25 Carbon Series cars with full, exposed carbon-fibre bodywork, and this example has recorded only 23 kilometres from new. Delivered new to the UAE, it remains unregistered and in as-new condition, allowing international collectors to acquire a flagship McLaren 675LT Spider with impeccable provenance and ultra-low mileage via an online sealed bidding process.
Collecting Cars’ latest Sealed Bids event unites some of the rarest and most historically significant cars of their eras, from Porsche’s Group C dominance and the evolution of the 911 to 1960s Italian craftsmanship and 21st-century hybrid supercar innovation. The curated selection reinforces the platform’s position in the global online car auction market, offering serious enthusiasts a secure and transparent way to bid on landmark models.
Discussing the lineup, Edward Lovett, founder of Collecting Cars, said: "[Collecting Cars] Sealed Bids gives collectors access to some of the rarest, most significant cars in the world from anywhere – your sofa, the boardroom, or even an airport lounge. Whether it’s a factory Porsche prototype, a Group C legend, a concours-quality Maserati, or a modern McLaren with MSO provenance, the platform makes it simple to explore, bid and win. The best bit? No one will see your bid amount or the winning sum; it remains entirely private."
