LONDON, 6 NOVEMBER, 2025:
Collecting Cars’ November edition of Sealed Bids will be led by a 1990 Porsche 962C Group C racer and the first long-wheelbase Porsche 911 E prototype built by the factory. Joining the two icons are a 1962 Maserati 5000 GT originally commissioned 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. They will all open for online sealed bidding today, Thursday 6 November, ending on Thursday 13 November.
Headlining this edition of Sealed Bids is one of the most original factory-built Porsche endurance racers ever offered for sale. Chassis 962-163 was made in July 1990 for Brun Motorsport. It is one of just seven customer 962Cs built to full 1988 works specification and one of only three delivered new to the team. It remains accident-free and unrestored, having raced only twice in period 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 producing around 700bhp. After spending decades in prominent private collections, it was sympathetically recommissioned in 2023 by Katana Ltd, preserving its originality while ensuring it remains track-ready. Utilising the Sealed Bids mechanism and Collecting Cars’ growing roster of worldwide bidders and collectors, it will be offered for sale this month via the online platform.
Equally significant is the 1968 Porsche 911 E prototype, chassis 119200001, a rarity in itself, but even more so as it is understood to be the first time the car has ever been offered for sale publicly. This factory-documented ‘Versuch’ (prototype) vehicle is confirmed as the very first long-wheelbase 911 E built, featuring the first Bosch mechanical fuel injection (MFI) engine and the first magnesium crankcase for a roadgoing 911. Originally constructed as prototype chassis 320012 before being renumbered by Porsche, it bridges the transition between short- and long-wheelbase production. It’s also the only known 911 on record that had a full factory conversion from left-hand drive to right-hand drive. Its provenance includes ownership by racing driver Robs Lamplough, F1 business supremo Paddy McNally and works driver and two-time Le Mans class winner Jo Siffert. Following more than 25 years off the road, the car underwent a £280,000 restoration by leading UK specialists, retaining its matching-numbers engine and gearbox.
Other highlights in the Sealed Bids event include a 1962 Maserati 5000 GT by Allemano, chassis 103.042, commissioned for Adolfo López Mateos, then President of Mexico; and one of only 34 examples ever built. A Maserati fan, he is the only person on record to have owned two of these remarkable grand tourers. Its fascinating life saw it later pressed into service with the Mexican police before resurfacing in the United States, passing through the hands of noted Maserati specialists such as Jerry Wood and Keith Duly. With a concours-quality restoration having been completed in 2024, the car now gleams in its original Grigio Montebello with blue Connolly leather interior, with its engine and gearbox also freshly rebuilt.
From one Italian icon to another, more modern variant, Collecting Cars has attracted a 2022 Lamborghini Countach LPI 800-4. One of just 112 made, its hybrid V12 produces 803bhp and a top speed of 221mph. The example offered is an original UK-supplied car finished in Rosso Scintilla, recently serviced at Lamborghini Edinburgh and showing 6,526 miles – now an opportunity to buy one of the most significant and exclusive modern Lamborghinis.
Completing the line-up is a McLaren 675LT Spider MSO Carbon Series, one of just 25 built, with a full exposed carbon-fibre body and only 23 kilometres recorded. Delivered new to the UAE, it remains in as-new condition and unregistered, making it one of the most desirable modern McLarens for collectors worldwide.
The latest Sealed Bids event from Collecting Cars brings together some of the rarest and most historically significant models of their respective eras, from Porsche’s Group C dominance to the evolution of the 911, and from 1960s Italian craftsmanship to 21st-century hybrid supercar innovation.
Discussing the line up, 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.”
The Collecting Group continues to redefine the experience of buying and selling collectibles online, combining transparency, expertise, and global reach with record-breaking results and an engaged enthusiast community.
These cars open for bidding today, Thursday 6 November, for seven days, finishing on Thursday 13 November.
