Broad Arrow Auctions will return to Knokke-Heist, Belgium, for its second Zoute Concours Auction on October 9, 2026. Held at Approach Golf during Zoute Grand Prix Car Week, the sale follows the auction house’s debut at the event in 2025, which generated more than €26 million and achieved a 78 percent sell-through rate.
The 2026 catalogue covers competition cars, pre-war machinery, post-war grand tourers and more recent supercars, with several one-off and unusually specified models among the consignments. Viewing will take place from October 7, ahead of the auction on Friday afternoon. Here are a few choice selections from the Broad Arrow Zoute Concours Auction… what do you have your eye on?
This Porsche 918 Spyder is number 142 of the 918 examples produced. It combines the optional Weissach Package with an unusual Paint to Sample specification. Delivered through Porsche Zentrum Düsseldorf, it is believed to be the only European-market example finished in Sport Classic Grey, a colour originally developed for the limited-production 997-generation 911 Sport Classic. Its exterior is paired with a Leather to Sample Espresso interior with contrasting Espresso piping. The original owner also selected the carbonfibre interior package, front-axle lift system, Burmester surround-sound system and six-point racing harnesses.
The car has covered 18,870km and retains a service book documenting maintenance from delivery onwards. Porsche Centrum Gelderland completed its ten-year inspection in March 2025, while a further €35,000 of work in September 2026 included servicing the PDK transmission and air-conditioning system, plus fitting a new windscreen. It’s estimated at €2.6m-€3m at the Zoute Concours Auction.
This matching-numbers Mercedes-Benz 300 SL Gullwing was completed on July 25, 1955 and delivered new to Switzerland in Silver Grey Metallic with a blue vinyl and plaid interior. Its factory specification included the more powerful NSL engine, fitted with sports camshafts said to add 10bhp, plus Rudge centre-lock wheels and the higher-speed rear-axle ratio.
The earliest recorded owner was Hans Huwyler, proprietor of Touring Garage in Lenzburg, who was also a Mercedes-Benz and Simca technician. Huwyler acquired the car from a doctor in Bern during the 1960s, by which time Mercedes-Benz had reportedly repainted it in its present green. Areas of the original silver remain beneath the paint, while much of the interior and mechanical specification has survived unrestored.
Huwyler recorded journeys, maintenance and oil changes in detail. His family retained the Gullwing for almost half a century, exporting it to California in 1994 before it returned to Europe in 2006. It was then acquired by 300 SL specialist Ben Valkenburg, from whose collection it is now offered. It’s covered 72,000km, but two accompanying logbooks indicate a total of 172,000km.
Original features include the silver-painted dashboard, Becker Mexico radio, three underbody belly pans, six-fin brake drums and the factory lead seal around the fuel-filler neck. Swiss-market details include a cold-weather radiator shroud, while the car has received awards at events including Schloss Dyck, Brooklands and Mercedes-Benz Classic Days. It’s estimated at €1.7m-€2m.
One of two McLaren P1s delivered new to Belgium, this single-owner example has covered just 293km. P1 number 352 was completed on April 24, 2015 and specified in MSO Storm Grey, with visual and gloss carbonfibre exterior components, the Stealth Pack and silver lightweight wheels. Its approximately €50,000 of options also included carbonfibre racing seats and a Carbon Black Alcantara interior.
Delivered to its Brussels-based owner in 2015, the P1 has been maintained exclusively by McLaren Brussels despite its minimal mileage. Its most recent service was completed in July 2026, when the high-voltage battery was tested at 92 percent capacity. The car retains its original tyres and is accompanied by its stamped service book, owner’s handbook, two keys in a carbonfibre presentation box, scale models and a letter from then-McLaren chief executive Mike Flewitt. Its Belgian technical inspection remains valid until June 2027. It’s estimated at €1.4m-€1.8m at the Zoute Concours Auction.
This EVO37 is number 18 of the 37 examples produced by Kimera Automobili. Although registered as a 1976 Lancia, it was completed in March 2025 using a Beta Montecarlo donor chassis that was stripped, reinforced and clothed in a carbonfibre body inspired by the Group B Lancia Rally 037. Its twin-charged 2.1-litre 16-valve four-cylinder engine was built by Italtecnica, and it uses both a supercharger and turbocharger to produce 498bhp and 406lb ft. Power reaches the rear wheels through a six-speed Dana Graziano manual gearbox. Further mechanical changes include Öhlins double-wishbone suspension and Brembo carbon-ceramic brakes. Kimera quotes a 0-62mph time of approximately three seconds and a top speed of 193mph.
Number 18 is finished in Kimera Luci del Bosco, a metallic brown inspired by a period Lamborghini colour, with gold wheels and beige leather covering its carbonfibre seats. The specification also includes a wooden gearknob, exposed gear linkage, air-conditioning, LED headlights, anti-lock brakes, parking sensors and a camera-based rear-view mirror. The car had covered 237km when catalogued. Kimera has offered to assist its next owner with registration and importation into Europe or the US. It’s estimated at €950,000-€1.15m.
Completed on September 22, 2005, this German-market Carrera GT is number 1056 of the 1270 examples produced. It is one of 80 finished in Guards Red and retains its original paint, engine and transmission. The Dark Grey leather interior has the optional XT seats, which added 15mm to the width of both seat cushions. The original buyer also selected manual air-conditioning and the Porsche Online Pro CD radio with Bose audio.
The car has covered 20,423km and has had four owners in Germany. Its previous keeper had it for almost 15 years and added approximately 1000km. A 41-page report prepared by Carrera GT specialist Jochen Bader in May 2026 records that the paint, engine and transmission are original.
Porsche Zentrum Stuttgart maintained the car between 2009 and 2025. Work completed in April 2025 included an engine service, a replacement battery and the APA3 suspension recall. The accompanying items include its books, tools, centre-lock socket and part of the original Dark Grey luggage set. It is estimated at €2.7m-€3.3m.
This Virage Volante was built in left-hand-drive form in January 1994, before returning to Aston Martin Works Service in 1997 for its 6.3-litre conversion and Wide Body bodywork. It is one of 24 Volantes upgraded with both features. The conversion increased the V8’s capacity from 5.3 to 6.3 litres, raising output from 330bhp to 459bhp. Associated changes included revised suspension, 18-inch OZ wheels and 14-inch ventilated AP Racing brakes. This car retained its five-speed ZF manual gearbox and is believed to be the only left-hand-drive 6.3-litre Wide Body Volante fitted with that transmission.
During the conversion, the car was repainted in Porsche Midnight Blue Metallic and fitted with a Dark Blue mohair hood. The cabin combines Parchment leather with Dark Blue carpeting and an Alcantara headlining. It was also converted to German-market specification because its owner was then living in Bad Homburg. The Aston Martin has covered less than 18,000km, and invoices record servicing through 2015, including work by Noble House Classics in the Netherlands. It passed to a Dutch collector in 2022 and was acquired by its current French owner in April 2026. Offered without reserve at the Zoute Concours Auction, it is estimated at €100,000-€150,000.
This 575M Maranello was delivered through an official Ferrari dealer in Modena before being converted by Kaeve Supreme Cars in the Netherlands. It is one of two road cars modified by the company in the style of Ferrari’s 575 GTC endurance racer, although it retains the production car’s drivetrain and is not an original competition chassis.
The five-year conversion replaced almost every exterior panel with bespoke carbonfibre components, leaving only the original roof and door skins. The wider body incorporates a front splitter and cooling ducts, extended wheelarches, an adjustable rear wing and a large rear diffuser. It is finished in Tour de France Blue and sits on centre-lock wheels fitted with Michelin Pilot Sport Cup 2 tyres. The suspension uses Intrax dampers and springs developed for the car’s wider track, while the standard Ferrari braking system is retained.
Its 5.7-litre V12 remains largely unmodified and produces 508bhp, with changes limited to high-flow air filters and a TÜV-approved sports exhaust. Power is transmitted through the original six-speed F1 automated manual gearbox. Inside, the car has Sparco bucket seats, an integrated rear rollcage, carbonfibre door panels, sliding Lexan side windows and Alcantara covering the dashboard, centre console and headlining. It is estimated at €225,000-€260,000 at the Zoute Concours Auction.
This E39 BMW M5 was used to test an experimental Volkswagen W10 engine developed under Ferdinand Piëch. Built on March 2, 1999, the car had its original 4.9-litre S62 V8 replaced by a naturally aspirated 5.0-litre all-aluminium W10. One of three W10 engines reportedly produced, the unit develops 473bhp and 437lb ft and is connected to a six-speed manual gearbox. The engine operates through a standalone management system, while the M5’s traction-control, stability-control and anti-lock braking systems were disabled during the conversion.
Sabine Willeke, who led the engineering team, has stated that Piëch used the car as personal transport during its development. The project was undertaken outside Volkswagen’s regular research and development programme, although the company is said to have funded it at a cost approaching €2m. The W-engine layout was subsequently used in Volkswagen Group production cars, culminating in the Bugatti Veyron’s quad-turbocharged W16. Finished in Carbon Black Metallic with black leather, the M5 retains a largely standard cabin apart from additional instruments and a replacement Stack display. As the Stack unit has no odometer, the car’s total mileage is unknown.
The present owner acquired the prototype approximately ten years ago and registered it in Slovakia. It does not have a certificate of conformity but remains road registered and was serviced in 2025. A second W10 engine mounted on a display stand and a design sketch are included in its sale at the Zoute Concours Auction. It is estimated at €250,000-€350,000.
This one-off shooting brake was commissioned as a reinterpretation of the Ferrari 365 GTB/4 converted for US Ferrari distributor Luigi Chinetti Jr in 1972. It was designed by Niels van Roij Design and uses a 2009 Ferrari 599 GTB Fiorano as its basis. Approximately 15,000 hours were spent on its design, engineering and construction. With the exception of the doors, every exterior panel was replaced by hand-formed aluminium bodywork. The original 599 windscreen and door apertures remain, but the roof rises slightly above the cabin before extending into a truncated estate-car tail.
As on the 1972 car, there is no conventional tailgate. Instead, electrically operated side windows hinge upwards to provide access to the luggage compartment, while the rear window remains fixed. Other additions include bespoke lighting, polished wheels, a carbonfibre rear diffuser and four integrated exhaust outlets. The 599’s naturally aspirated 6.0-litre V12 and six-speed automated manual transmission retain their original specification. Cognac leather covers the seats, dashboard, doors, headlining and luggage compartment. The instrument binnacle has been relocated to the centre of the dashboard, while the rear compartment incorporates a carbonfibre shelf and six machined-aluminium runners.
The car was unveiled at Woodcote Park in July 2026 and has 43,802km on the clock. It is accompanied by German registration documents identifying the underlying Ferrari as a 2009 model. It’s estimated at €450,000-€650,000.
This 850 CSi was ordered in Violet Blue Metallic with a matching Violet Blue leather interior. Of the 35 E31-generation 8 Series cars reported to have received this paint colour, four are understood to have been 850 CSis. Its factory equipment includes an electric sunroof, heated and electrically adjustable memory seats, wood trim, a BMW Business CD radio, six-disc CD changer and upgraded HiFi speakers. It underwent its pre-delivery inspection in Kronberg, Germany, on June 21, 1993.
It was subsequently used in Spain during the late 1990s and returned to Germany in 2014; it’s covered 63,000km. Offered without reserve at the Zoute Concours Auction, the BMW is estimated at €125,000-€150,000.
Delivered through Monza in Sint-Martens-Latem in February 2015, this LaFerrari is believed to be one of five supplied new in Belgium. It has remained in the country since delivery and had one registered owner from new. The car is finished in Grigio Ferro Metallizzato with a Nero roof. Its specification includes the carbonfibre exterior package, matt-finished wheels, aluminium-coloured brake calipers, suspension lift and Ferrari Telemetry. The Nero leather interior has four-point harnesses, Grigio Scuro Cavallino embroidery on the head restraints and a factory fire extinguisher.
The LaFerrari has covered 13,069km, and the service book records maintenance within the Ferrari dealer network in 2016, 2017, 2019, 2025 and 2026. Francorchamps Motors Brussels carried out the three most recent visits. Testing in July 2026 identified an elevated temperature in one cell of the high-voltage battery. Ferrari subsequently authorised replacement of the complete battery pack under the LaFerrari Power Warranty, with the work completed in August 2026. It’s estimated at €4m–€5m.
