Bonhams and Broad Arrow bring two very different but equally compelling collector-car auctions to Knokke-Heist

There are few places in Europe where the collector-car world becomes quite as concentrated as Knokke-Heist during Zoute Grand Prix week. From 7 to 11 October, the Belgian seaside resort once again becomes a meeting point for collectors, manufacturers, dealers and enthusiasts — and this year’s auction programme is particularly strong.

Two major sales dominate the week. Broad Arrow’s Zoute Concours Auction takes place at Approach Golf on Friday 9 October, while Bonhams’ Zoute Sale returns to the marquee beside the Grand Casino on Sunday 11 October.

For Porsche enthusiasts, the contrast between the two catalogues is fascinating. Broad Arrow has assembled a particularly deep selection ranging from a 1953 356 Pre-A to a Carrera GT and a very special 918 Spyder Weissach. Bonhams, meanwhile, offers a more varied Porsche selection, mixing early 356s, a 914/6, RUF-developed 911s, a 911 RS and modern GT machinery.

Broad Arrow: the modern Porsche supercar story

Broad Arrow’s second Zoute Concours Auction is arguably the more spectacular of the two Porsche line-ups. The catalogue contains approximately 70 collector cars, and its Porsche selection stretches from the earliest years of the 356 to the hypercar era. The 2025 inaugural sale generated €26.3 million in sales with a 78-percent sell-through rate, setting a considerable benchmark for the second edition.

At the top of the Porsche section sits a 2005 Carrera GT, estimated at €2.7–3.3 million. Chassis WP0ZZZ98Z6L000072 is Carrera GT number 1056, one of only 80 examples finished in Guards Red. With 20,423 kilometres, original paint, matching drivetrain and a documented Porsche service history, it is one of the catalogue’s most significant analogue supercars.

Even more spectacular on paper is the 2015 Porsche 918 Spyder Weissach Package, estimated at €2.6–3.0 million. Number 142 of 918, chassis WP0ZZZ91ZFS800142, is described as the only European-delivery 918 finished in Paint to Sample Sport Classic Grey with an Espresso Leather-to-Sample interior. It also has the €60,000 Weissach Package and has covered 18,870 kilometres.

The 918 is particularly interesting because it forms one-third of what Broad Arrow itself calls the modern hypercar “Holy Trinity”: alongside it sit a 2015 Ferrari LaFerrari, estimated at €4–5 million, and a 2015 McLaren P1 estimated at €1.4–1.8 million. The P1 has covered just 293 kilometres.

For Porsche collectors, however, there is plenty to like below the seven-figure level.

The 2018 911 GT2 RS Weissach Package Clubsport is a particularly unusual combination. Chassis WP0ZZZ99ZJS180628, finished in Paint to Sample British Racing Green, has covered just 16,218 kilometres and carries both the Weissach and Clubsport packages. Its estimate is €400,000–500,000.

At the opposite end of the Porsche timeline is the 1953 356 Pre-A “Knickscheibe” 1500 Cabriolet, chassis 60077. Offered without reserve, it carries an estimate of €140,000–180,000. Its early “bent-window” configuration and documented Kardex history make it one of the more historically significant Porsches in the sale.

The catalogue also offers a charming 1968 911 L “Soft-Window” Targa, one of only 307 Rest-of-World examples produced for that model year. Chassis 11860271 retains its matching-numbers drivetrain and was reportedly kept by its original owner for 57 years. The estimate is €150,000–180,000.

And for those who prefer their Porsches slightly less obvious, the 2003 911 Carrera RUF 3.6 Kompressor is worth close attention. Chassis WP0ZZZ99Z3S605887 has RUF’s supercharger conversion, producing 409 horsepower, and comes with an extensive RUF history file. It is estimated at €165,000–185,000 and offered without reserve.

And then there is the rest of Broad Arrow’s catalogue

The Porsche story should not obscure some extraordinary non-Porsche entries.

The aforementioned Ferrari LaFerrari is the headline car at €4–5 million, while the McLaren P1 at €1.4–1.8 million gives Broad Arrow an unusually strong hybrid-supercar trio.

Elsewhere, the catalogue includes a 1955 Mercedes-Benz 300 SL Gullwing, described as one of the best preserved unrestored examples in the world, a 1937 Bentley 4¼-Litre Aerofoil Sport by Gurney Nutting, a 1967 McLaren M4A Formula 2, a 1976 Lancia Stratos HF Stradale, a Ferrari 365 GT4 BB and a Ferrari F355 GTS.

There is also a particularly Belgian curiosity: the 1965 APAL GT Coupé, built in Belgium and inspired by the Porsche 356 B GTL Abarth Carrera. It is estimated at €60,000–90,000.

Bonhams: a broader Porsche spread

Bonhams approaches Zoute from a somewhat different angle. Its sale on Sunday 11 October contains 174 lots, with the Porsche selection ranging from a 1960 356 B T5 to a modern 992-generation GT3 Touring.

The most intriguing Porsche may well be the 1989 Porsche 911 Type 964 Carrera 4 RUF RCT Coupé, lot 119. Chassis WP0ZZZ96ZKS400562 is a Finnish-delivery car converted by RUF, with a turbocharged engine producing approximately 425 bhp. It is listed at €300,000.

At the other end of the spectrum, the 1992 Porsche 911 Carrera RS, chassis WP0ZZZ96ZNS490836, carries an estimate of €180,000–220,000 and is offered without reserve. The 2008 Porsche 911 GT3 Cup S, chassis WP0ZZZ99Z85798331, is another competition-oriented Porsche, estimated at €60,000–80,000 and also offered without reserve.

The 2021 911 GT3 Touring provides the modern counterpoint. With only 3,196 kilometres, chassis WP0ZZZ99ZNS263416 is estimated at €125,000–150,000.

Bonhams’ 356 offerings are equally interesting: the 1960 356 B T5 1600 Cabriolet is estimated at €90,000–120,000, while the 1957 356 A T1 1600 Cabriolet carries an estimate of €140,000–160,000.

Beyond Porsche at Bonhams

Bonhams’ catalogue is especially attractive if the objective is variety. The early lots include a 1970 Ferves Ranger, 1969 Alfa Romeo 1750 GTV, 1997 Ferrari 456 GT, 1994 Lancia Delta HF Integrale Evo 2, 2003 Ferrari 575M Maranello, 1951 Jaguar XK 120 Roadster, 2000 BMW Z8, 1967 Mercedes-Benz 250 SL, and 1962 Ferrari 250 GTE 2+2.

Further down the catalogue, the highlights include an AC Cobra 289, a Lamborghini Miura P400 S, a Lamborghini Countach 25th Anniversary, several Ferrari V8s and V12s, and a collection of Italian GT cars. The combination gives Bonhams a distinctly traditional Zoute flavour: less concentrated on headline hypercars, but extremely broad in period and character.

Two auctions, two Porsche philosophies

Taken together, the two sales offer a fascinating snapshot of where Porsche collecting stands in 2026.

Broad Arrow is the more concentrated Porsche statement. Its Carrera GT and 918 Spyder alone place two of Porsche’s most important modern analogue/hybrid supercars in the same room, while the GT2 RS Clubsport, 911 R and RUF 3.6 add depth to the modern-collector side of the catalogue. At the historic end, the 1953 356 Pre-A and 1968 Soft-Window Targa provide a useful counterweight.

Bonhams is more eclectic. Its 964 RUF RCT, Carrera RS and 914/6 are arguably the most interesting enthusiast cars, while the 356s and modern GT3 Touring demonstrate the breadth of Porsche’s appeal.

For the Porsche enthusiast, therefore, Zoute Grand Prix 2026 is not simply a question of choosing between two auction houses. It is an opportunity to walk through two quite different interpretations of the marque’s collecting landscape — from early 356s and soft-window Targas to RUF specials, GT3s, Carrera GTs and the 918 Spyder.

And with the Broad Arrow Holy Trinity of LaFerrari, P1 and 918 Spyder adding an extraordinary modern-supercar dimension, this year’s Zoute auctions have the ingredients for one of the most interesting collector-car weekends of the European autumn.
