Iconic Auctioneers returns to Sywell Aerodrome on May 16 for its Supercar Fest 2026 sale, with 110 cars in its Iconic sale and 70 lots in its Classic sale. Although the emphasis is largely on more modern performance cars, there are one or two surprises along the way – including a Mercedes-Benz with Marilyn Monroe connections.
The Supercar Fest sale sees a couple of Lamborghinis up for grabs, with this 2000 Diablo VT 6.0 a key draw. Finished in Nero Pegaso with a Nero Pegaso leather interior and Grigio inserts, this Diablo was first registered in Switzerland and supplied by Lamborghini Porrentruy. Early service records indicate regular use and consistent maintenance, with work carried out by the supplying dealer at 2824km, 12,803km and 36,733km between 2000 and 2002. Additional servicing was completed by P3 Automobiles in Cannes and Garage Remsa in Sion, with mileage reaching 45,100km by 2007.
The car was imported to the UK in 2012 and has remained here since. It was serviced by Rardley Motors shortly after arrival and saw limited use in the following years, passing through a small number of owners. In 2022, it underwent further servicing by SB Racing, including a full service, replacement of interior switchgear and fitting of new Pirelli P Zero Asimmetrico tyres. It’s estimated at between £350k and £400k.
Delivered new to Switzerland in Argento with a Bordeaux Connolly leather interior, this 1966 Ferrari 330 GT 2+2 Series 2 Ferrari was supplied via Italauto SA in Lausanne to its first owner, Pierre Busy. It remained in Switzerland for several decades, passing through a small number of owners including a Basel-based architect, Fritz S Kern of Arlesheim and Ernst Scheidegger of Brunnen. By the early 1990s the car was noted as largely unused for an extended period, and it retained a high degree of originality. It was acquired by another Swiss owner in 1994 before being exported to Belgium in 2003, where it remained until 2022. At that point, it was purchased by the current owner, showing approximately 46,000km.
At the time it was fitted with engine number 9059. The 330 GT has since been the subject of significant mechanical work, including a full engine rebuild by Ferrari specialist Foskers using its original matching-numbers cylinder block. Additional work has included overhaul of the gearbox, suspension and brakes, along with refurbishment of the carburettors, instruments and interior trim. More recent maintenance carried out in 2025 included attention to bearings, fuel-system components, air-conditioning and heating. The car is accompanied by a history file including registration documents, specialist reports and invoices detailing work carried out over recent years. The replacement engine is included separately, and at the Supercar Fest 2026 sale it’s estimated at £210k-£240k.
This UK-supplied, right-hand-drive De Tomaso Pantera was delivered new by MTC Cars, with period documentation confirming its specification with GTS components at the point of supply. The car has had one previous owner and showed 23,232 miles at the time of cataloguing. It has since been the subject of a four-year restoration, during which the bodyshell was stripped and rebuilt, with mechanical and cosmetic work carried out to return it to its original specification. It retains its matching-numbers 351 Cleveland V8 engine and ZF five-speed gearbox. It’s estimated at between £120k and £130k.
This UK-supplied right-hand-drive 1959 AC Ace Bristol was delivered new to Ivor William Ward of Purley. It remained with its first owner until 1964 before passing through several short-term custodians. In August 1966 the car was acquired by Peter John Williams, who retained it until 1979. During his ownership, it was refinished from its original white to its current red. The car entered its current ownership in 2003 and has been maintained and periodically serviced, including recent work carried out in March 2025 by INRacing Ltd, when a new clutch was fitted and an overdrive system installed. It’s estimated at £180k-£220k.
This 1970 Mercedes-Benz 280 SL is one of a small number fitted with the optional ZF five-speed manual gearbox, a feature offered only late in the W113 production run and specified on relatively few cars, particularly in right-hand-drive form. The 280 SL has been in its current ownership for approximately 16 years. During this time, it has undergone a comprehensive programme of restoration and maintenance. In 2020, the car was dismantled and refinished by O’Keeffe Coach Trimming Services, including body, trim and brightwork.
At that stage it was repainted from its original Moss Green to Beige Grey Metallic, with the interior retrimmed in Parchment. Further mechanical work followed in 2023, when the engine was rebuilt in conjunction with Mercedes-Benz specialist Roger Edwards Motors. Additional updates include the installation of a Becker head unit and a discreet audio system. It’s estimated at between £140k and £160k.
This 1969 Ford Shelby Mustang GT350 Fastback is one of 217 built in Gulfstream Aqua, and was first delivered to Belgium by Claude Dubois. It’s described as being unrestored condition and it comes from a UK collector; and at the Supercar Fest 2026 sale it’s estimated at between £90k and £120k.
More familiar fast Ford turf for Iconic here, with this 2956-mile 1992 ‘big turbo’ Ford Escort RS Cosworth. It was supplied by John Grose Ford of Ipswich, finished in Diamond White with a Polaris Grey interior, with electric windows, sunroof and headlamp washers. The first owner used it sparingly and kept it dry stored and maintained by the supplying dealer. By the time it changed hands in 2016, it had covered 2495 miles following recommissioning. Since then it’s had minimal use and has been kept in a temperature-controlled environment. It’s estimated at £115k-£130k.
This 1964 Ferrari, chassis 5887, was delivered new to Italy before being exported to the US and subsequently imported into the UK in 2002, where it has remained since. Since arriving in the UK, the car has been in the care of a small number of owners. One of these was a qualified motor engineer and Aston Martin specialist, who maintained the car and used it regularly, including on European tours. During this period it underwent a body restoration, involving a full strip-down and rebuild, with attention given to panel fit before being refinished in Pozzi Blu. The current owner acquired the car in 2013 and has continued its maintenance with a recognised Ferrari specialist, with recorded work extending into the late 2010s. It’s estimated at between £175k to £200k.
This 1950 Mercedes-Benz 170 S was used by Marilyn Monroe during a stay in Greece in 1956. Imported through the port of Piraeus in February of that year, it is supported by period insurance documentation signed ‘Marilyn Monroe’; covering February to August 1956, this corresponds with her time in Europe prior to her marriage to Arthur Miller. This association was identified by the current owner following the discovery of fitted luggage bearing ‘MM’ insignia and a bespoke dashboard plaque.
Further investigation through Greek registration and insurance archives led to the recovery of the original insurance certificate, which has since been apostilled, notarised and certified by the UK Foreign, Commonwealth & Development Office. The same documentation records the car as a ‘Special Category Vehicle’, a designation used at the time for high-profile individuals.
The 170 S was acquired by its current owner more than a decade ago and subsequently underwent a comprehensive restoration by Brookfield Classic Cars, overseen by Steve Nott and Gavin Bicknell. The work involved complete disassembly and rebuild, with components sourced from original suppliers where possible or remanufactured using factory drawings and period methods. Reference was taken from an unrestored example, with input from former Sindelfingen engineers. It’s estimated at between £120k and £160k.
One of 17 right-hand-drive ‘88½’ Lamborghini Countach 5000 QV models built, this car is also understood to be among the final examples completed. It was supplied new on August 4, 1988 via Lamborghini London Limited to its first owner in Bristol. The car has remained in the UK throughout its life and has passed through a limited number of custodians. It was acquired by the current owner in 2016 and has since been maintained by Lamborghini specialist Mike Pullen of Carrera Sport in West Sussex. At the Supercar Fest 2026 sale, it’s estimated at between £550k and £650k.
