This year’s Zoute Grand Prix, set against the opulent coastal backdrop of Knokke-Heist, is shaping up to be a notable edition for the car collecting community. Buyers will find more choice than ever in 2025, with Broad Arrow joining the line-up as part of its rapid European expansion, while Bonhams returns with its traditional sale. Between them, the two auction houses have assembled catalogues full of temptations – and we’ve highlighted five of our favourites from each below.
BROAD ARROW AUCTIONS: ZOUTE CONCOURS AUCTION, 10 OCTOBER, 2025
1998 Lamborghini Pregunta (est. €2,500,000 – €3,500,000)
While narrowly outgunned in Broad Arrow’s pre-auction estimate hierarchy by the Ferrari 275 GTB/4 below, there’s no denying that this Lamborghini Pregunta concept is the most attention-grabbing car in the auction catalogue.
Based on Diablo underpinnings and inspired by jet fighter aircraft, the one-of-a-kind Pregunta previewed a number of technological and styling trends of the new millennium, including carbonfibre bodywork, an F1-derived digital instrument cluster and rear-view cameras in place of wing mirrors.
Despite being one of the most dramatic and forward-thinking concept cars of the 1990s, the Pregunta has rarely been seen since making its showstopping debut at the 1998 Paris Motor Show, just a few months after Lamborghini was acquired by the Volkswagen Group.
Unlike many wild concepts, it is completely driveable and powered by the same 5.7-litre V12 found in the Diablo supercar. It sends 529bhp to the rear wheels via a five-speed gated manual transmission.
1967 Ferrari 275 GTB/4 (est. €2,700,000 – €3,200,000)
Leading Broad Arrow’s catalogue with the highest pre-sale estimate is this 1967 Ferrari 275 GTB/4 – one of only six factory finished in stunning Verde Pino paintwork.
Originally destined for the Crepaldi dealership in Milan, chassis 10563 was instead delivered to Bill Harrah’s Modern Classic Motors in Nevada via famed US Ferrari importer Luigi Chinetti. It was then acquired by the Hodges Chemical Company in California before passing to motorcycle dealer Roger Selby.
It remained in the US until 2017, passing through the hands of a number of discerning Ferrari collectors, including plastic surgeon and gentleman racer Dr Ronald ‘Hot Rod’ Finger and former Starbucks CEO Orin Smith.
Now in European ownership, chassis 10563 has never required a complete restoration and is a high original matching numbers example offered with Ferrari Classiche Red Book certification.
2023 Aston Martin Valkyrie (est. €2,400,000 – €2,800,000)
Consigned directly by former Formula 1 star Daniel Ricciardo, it’s unsurprising that this 2023 Aston Martin Valkyrie has proved to be one of the most headline-grabbing lots of Broad Arrow’s catalogue.
During his Red Bull Racing years, Ricciardo was closely associated with the Valkyrie project – a collaboration between his team and Aston Martin. That connection inspired the eight-time Grand Prix winner to commission chassis 089, specified with a host of bespoke touches by Aston Martin’s Q division.
One of just 150 examples built, Ricciardo’s Valkyrie has covered only 160km from new.
1985 Citroën BX 4TC (est. €100,000 – €150,000)
One of the most desirable Citroëns ever conceived, the ultra-rare BX 4TC was the result of the French marque’s short-lived foray into the World Rally Championship’s legendary Group B era.
One of just 86 homologation cars produced, this example was gifted by Citroën to French F1, endurance and rally driver Jean-Pierre Beltoise in 1988. He retained the five-door rally special until 2005, when it was sold in Monte Carlo as part of his collection to the current owner.
Preserved in storage ever since and never registered for road use, it shows only 197km from new. The car is accompanied by a 1988 letter from Citroën commercial director Georges Falconnet, confirming it was presented to Beltoise.
1935 Aston Martin 1.5-Litre Mark II Long Chassis-Sports Saloon (est. €65,000 – €85,000)
Pre-war Astons are notoriously rare and this matching numbers Mark II is believed to be one of only three built in two-door long-chassis configuration. Originally registered in England in 1935, the car passed through the hands of three owners before being acquired by Fuad Majzub in 1975 and remained in his family’s ownership ever since.
Offered with its original coachwork in barn find condition, this Aston is a prime restoration candidate; its sister car won silverware at this year’s prestigious Pebble Beach Concours d’Elegance.
BONHAMS: THE ZOUTE SALE, 12 OCTOBER, 2025
2005 Maserati MC12 Stradale (est. €3,400,000 – €4,000,000)
Leading this year’s 85-lot Bonhams sale is this one-owner Maserati MC12 Stradale. One of just 50 examples built for GT1 racing homologation, the car was delivered to its Italian owner in 2005 and has covered 44,000km during its lifetime.
1966 Porsche 906 Carrera 6 Works Factory Prototype (est. €1,600,000 – €2,200,000)
As an early progenitor of the legendary Le Mans-winning 917, the 906 ranks among Porsche’s most significant race cars. This example, chassis 906-017, is the second officially recorded 906 and initially served as a factory development car in the winter of 1965. It went on to make the model’s public debut at the 1966 press unveiling, before claiming sixth place at that year’s Daytona 24 Hours with Herbert Linge and Hans Herrmann. Its period racing career concluded as a factory test car for the 1966 Targa Florio and Monza 1000km.
Following its move into private ownership, the car underwent a comprehensive five-year restoration by Freisinger-Motorsport in 2008. It is now offered from one of France’s largest collections and remains road-registered in Germany.
1986 Lamborghini LM002 (est. €350,000 – €400,000)
Although derived from an ill-fated military project, the LM002 can, from today’s perspective, be seen as a precocious machine that anticipated the modern luxury SUVs now produced by Ferrari, Aston Martin and, of course, Lamborghini.
Originally delivered to Oman, this early twin-Weber LM002 was later acquired by a Dutch doctor based in the region. It passed to its current Belgian owner in 1989 and has since covered just 12,800km, remaining in original, unrestored condition.
1950 Delahaye 175 S Coach (est. €180,000 – €220,000)
One of only 14 surviving Type 175s from the 51 built, chassis 815042 pairs elegant Motto coachwork with significant competition provenance. One of three Type 175 S models prepared for French rally star Jean Trévoux, it claimed overall victory on its debut at the 1951 Monte Carlo Rally before being driven by Bugatti legend Louis Chiron in that year’s Carrera Panamericana.
The car passed into the ownership of Baron Jules de Koenigswarter in 1952 and remained in Mexico. While there, its original engine was swapped for a Ford V8 and kept in storage for several years before being acquired by French expat Michel François, who managed to source the original engine and transmission.recovered the correct engine and transmission.
It was then owned by collector Jean Gorjat for 15 years, and more recently has been the subject of a major mechanical restoration. Interestingly, the car’s engine number ‘815050’ is from another Trévoux Type 175 S, which suggests it may have been delivered new with this engine, or it may have been sold to Michel François as the original powerplant.
The car is accompanied by period photography, an FIA Historic Technical Passport and a recent historical study by Club Delahaye’s honorary chairman Jean-Paul Tissot.
2002 Nissan Skyline GT-R V-spec II Nür (est. €350,000 – €450,000)
One of only 718 produced, the V-Spec II Nür marked the ultimate evolution of the Skyline R34 GT-R. Developed at the Nürburgring, it was equipped with a motorsport-derived RB26 twin-turbo straight-six featuring forged internals, larger turbos, gold cam covers and a 300km/h speedometer.
This QM1 White example is further enhanced with desirable Nismo upgrades, including aero components, an S-Tune front bumper, multi-function display and gear knob.
First registered in Japan in 2002 and exported to Europe in 2008, it now resides in Germany and has covered just 8959km from new.
