Collector Car Market Brief: A Belgian Record at Zoute, and Why the Cobra Went Home

Two auctions in Knokke-Heist last weekend gave the collector market its clearest read since Zurich, and the message was consistent across both rooms. Buyers paid in full for cars whose stories are finished. They hesitated, or walked away, when a car still came with an open question. Broad Arrow’s Zoute Concours Auction on October 9 made €34.6 million (about $39.1 million), the highest total for a collector car auction in Belgian history. A 2015 Ferrari LaFerrari closed the sale at €5,181,250, the most valuable car ever sold at auction in Belgium. Two days later, Bonhams’ Zoute Sale added €10.2 million. The 1965 AC Cobra 289 from our Lot of the Day was not among the cars that sold.

Broad Arrow: A Record Built on the Holy Trinity

Broad Arrow’s second Zoute sale, held during Zoute Grand Prix Car Week, offered more than 90 lots and sold 91 percent of them, according to the house’s official results release. Registered bidders rose more than 44 percent from 2025, more than a third were bidding with Broad Arrow for the first time, and they came from 33 countries. That last figure matters more than the total. A Belgian seaside sale drawing a third of its bidders new to the house is evidence of fresh liquidity, not just the same collectors trading cars among themselves.

The top of the sale was dominated by the hybrid generation that defined the hypercar a decade ago. All three members of the so-called Holy Trinity crossed the block, and all three sold:

• 2015 Ferrari LaFerrari (Lot 193), Grigio Ferro Metallizzato: €5,181,250
• 2015 Porsche 918 Spyder Weissach Package (Lot 173): €3,212,500
• 2005 Porsche Carrera GT (Lot 146): €2,762,500
• 2015 McLaren P1 (Lot 129): €1,890,625
• 2022 Ferrari 812 Competizione (Lot 130): €1,496,875
• 2010 Ferrari 599 GTO (Lot 121): €1,131,250
• 2020 Ferrari 488 Pista Piloti Ferrari (Lot 123): €838,750

All prices include buyer’s premium. The order is instructive. The LaFerrari, of which Ferrari built 499 coupés, outran a 918 that carries the Weissach Package most buyers of that car want. The 918 in turn comfortably cleared the P1. Within a closed set of three cars bought by the same kind of collector, the market is still ranking by marque and by how each car is remembered, not by lap times. Collectors rarely pay a premium for performance alone. They pay for the car that best represents the moment.

What Zoute Says About the Zurich Stall

Two weeks earlier, RM Sotheby’s Zurich sent home a Mercedes-AMG ONE, a Pagani Huayra Roadster, a Porsche 911 R and a Ford GT Carbon Series without a buyer, as we reported in our Zurich market brief. It was tempting to read that as a hypercar market losing its nerve. Zoute argues against that reading.

The cars that sold in Belgium are not new allocation cars still finding their level. They are ten years old or more, out of production, and their place in history is settled. The LaFerrari, 918 and P1 marked the start of the hybrid hypercar era. The Carrera GT is widely seen as the last great analog supercar from Stuttgart. The 812 Competizione is a limited series built around Ferrari’s naturally aspirated V12, and buyers increasingly see that engine as the end of something. None of these cars needs a buyer to take a leap of faith about what it will mean in 2036.

The Porsche 911 R makes the point more precisely than any hypercar. Zurich carried a 2016 911 R at CHF 550,000 to 600,000, before premium, and it did not sell. At Zoute, a 2016 911 R sold for €540,625 including premium, which Broad Arrow says was well above its upper estimate. Using the exchange rates implied in both houses’ results, the Belgian price lands below where Zurich set its low estimate. The car was never the problem. The number was. Buyers are not refusing modern collector cars. They are refusing to pay tomorrow’s price today.

The Cars That Didn’t Sell, and Why That Matters

A 91 percent sell-through still leaves a revealing list of cars unsold. Broad Arrow’s lot results show no sale for a 1955 Mercedes-Benz 300 SL Gullwing, a 2003 Aston Martin DB AR1 Zagato, a 1975 Ferrari 365 GT4 BB, a 1981 Ferrari 512 BB, a 1955 Lancia Aurelia B24S Spider and a 1991 Lancia Delta Integrale Futurista by Automobili Amos. These cars are blue chip or close to it, and none failed for lack of pedigree. Without published bids, the likeliest reading is a gap between reserve and room.

The Gullwing deserves the most attention. A 1957 300 SL Roadster sold in the same room for €1,041,250, and Bonhams sold a 1961 Roadster two days later for €1,265,000. Demand for the 300 SL is plainly intact. When a Gullwing fails to sell in a room full of new bidders, the question is usually the specific car and its documentation, not the model. We made that case this week in our look at how the data card decides a Gullwing’s identity.

The 1990 MCA Centenaire sold, but not where it was pitched. The car brought €821,875 including premium, below the €900,000 to €1.2 million estimate we covered in our pre-sale guide, Five Built, Three That Count. Broad Arrow’s release describes the Centenaire as the first road car with a carbon-fibre monocoque, a significant claim. Bidders still priced it as an obscure Lamborghini-powered curiosity with a complicated build history rather than a landmark. When the production count itself takes explaining, buyers tend to discount the explanation.

Records That Rewarded a Story

The results that cleared their estimates by the widest margins were cars with a single, legible story attached. A 2000 BMW M5 prototype, fitted at Ferdinand Piëch’s direction with Volkswagen’s W10 engine, sold for €411,250. Broad Arrow says that is a world record for an E39 and the most ever paid for a non-charity M5 at auction. The car is a footnote in the engineering line that led to the Bugatti Veyron’s W16. That footnote is what bidders paid for, not the M5 itself.

A 1987 Aston Martin V8 Vantage X-Pack made €647,500, a record for a V8 Vantage coupé. A 1992 Lamborghini Diablo brought €343,750 and a Lancia Stratos HF Stradale €625,000. The Kimera EVO37, a modern carbon-bodied revival of the Group B Lancia 037, sold for €1,131,250, tying the 599 GTO. For a restomod, that is a result that would have been hard to imagine five years ago.

Then there is the celebrity question we raised in our September market brief. Pete Sampras’s 2000 BMW Z8, owned by him from new until 2015, sold for €287,500, inside its €250,000 to €350,000 estimate. Bonhams supplied the control sample two days later. Its own 2000 Z8, with hardtop, sold for €212,750 in the same town. That puts the Sampras car roughly €75,000 above a comparable Z8 in the same week, before accounting for differences in mileage and condition. That is the clearest single measure of a celebrity premium Zoute produced. For the model’s fundamentals, see our BMW Z8 collector spec sheet.

Bonhams: The No-Reserve Test

Bonhams’ Zoute sale on October 11, which marked 14 years of the house’s partnership with the Zoute Grand Prix, sold 53 of 72 vehicle lots, a 76 percent sell-through, for €10.2 million. The house reported more than 800 registered bidders from 36 countries. The sale’s structure made it the more useful of the two for reading prices. Its centrepiece was the Keller Collection: twelve predominantly Italian sports and supercars offered without reserve. All twelve sold, for a combined €3,593,750.

We argued in our preview that the Keller sale would matter more than its estimates, and the results bear that out. The 1970 Lamborghini Miura P400S, chassis 4578, one of the late ventilated-disc cars, sold for €1,725,000. Bonhams charges a flat 15 percent premium on motor cars, so the hammer fell at €1.5 million, below the €1.6 million to €2 million estimate. That is not a weak result. It is an honest one. This Miura was repainted from its factory Arancio to Giallo Fly, and no reserve meant the room, not the consignor, decided what that change was worth.

Elsewhere in the collection, the 1989 Countach 25th Anniversary made €517,500 and the 1974 Ferrari Dino 246 GT €322,000. The most telling Keller result was a 1977 Ferrari 512 BB at €189,750. Across town, Broad Arrow’s 1981 512 BB, protected by a reserve, did not sell. Broad Arrow’s 365 GT4 BB failed to sell as well. Both houses had a Berlinetta Boxer. Only the one without a reserve found a buyer. A reserve records what the seller remembers about the market. A no-reserve sale records what the room believes today.

Outside the collection, the 1961 Mercedes-Benz 300 SL Roadster led at €1,265,000, followed by a matching-numbers 1968 Ferrari Dino 206 GT, the 28th of 152 built, at €563,500. A 1979 BMW M1 sold for €437,000, which works out to a hammer price well under its €450,000 to €550,000 estimate. The cars Bonhams lists without a result include an Aston Martin DB6 Shooting Brake (estimated at €500,000 to €600,000), a 2012 Mercedes-Benz SLS AMG (€280,000 to €320,000), a 2017 Lamborghini Huracán Spyder (€220,000 to €250,000) and a De Tomaso Mangusta (€280,000 to €300,000). Late-model supercars without a historical hook struggled here as they did in Zurich.

The Cobra: The Question Got an Answer, and the Market Still Hesitated

The 1965 AC Cobra 289, chassis COB6047 (Lot 160), was estimated at €700,000 to €900,000. As of October 13, Bonhams’ lot page shows the estimate and no sale price, which means it did not sell on the day. A post-sale deal remains possible.

Our preview asked when the car’s right-hand-drive-to-left-hand-drive conversion and red repaint took place. The full catalogue goes a long way toward an answer. COB6047 was built in right-hand drive, finished in Vineyard Green over beige, and sold new through H.R. Owen in Kensington on July 7, 1965, registered EYT 78C. Its first owner took it to California and drove it across the country and back. In the 1980s, Lynn Detzel of Oklahoma repainted it red, and the catalogue says Detzel “or possibly a subsequent owner” converted it to left-hand drive. The car later spent 24 years with one California owner before moving to France in 2011. It has since been comprehensively restored and retains its matching-numbers engine.

So the alterations date from four decades ago, in American ownership, and are traced in the car’s Cobra Register history. That is a better answer than many buyers feared. It is not a complete one. The catalogue hedges on who did the conversion, and a comprehensive restoration makes it harder to claim the “original, unmolested” character the pre-sale publicity promised. Buyers at this level compare cars against the best-documented examples on the market. A Cobra that is no longer in its delivery colours or its delivery configuration has to make up that difference elsewhere, and on Sunday the room was not willing to do it at the estimate.

That outcome fits everything else Zoute showed. The market was not short of money or bidders for Cobras or for anything else. It was short of patience for unresolved questions. Restoring COB6047 to Vineyard Green and right-hand drive would be a defensible decision for a future owner, and that is exactly the sort of cost a buyer subtracts before bidding.

What Serious Buyers Should Take From Zoute

The hypercar market is selective, not weak. Settled, out-of-production cars with clear historical roles are liquid at the top of the market. New allocation cars are liquid only when the consignor accepts today’s price. Sellers of recent limited editions should read the 911 R comparison carefully.

No-reserve results are the best price data available. The Keller sale produced a dozen honest numbers in an afternoon. Buyers tracking Miuras, Boxers and Countaches should treat those results as more reliable reference points than many reserve-protected sales.

Paperwork answers questions, but it cannot unmake changes. COB6047’s history is better documented than its pre-sale story suggested. The car still sits outside its factory specification. Documentation can explain an alteration. It rarely pays for one.

Celebrity is worth something, but it can be measured. The Zoute Z8 pair offers a rare same-week, same-town comparison. Treat about €75,000 as a provisional figure for one famous owner on one model, not a rule.

Belgium’s new auction record will draw the headlines, and it deserves to. The more durable lesson from Knokke-Heist is quieter. Over one weekend and two salerooms, collectors showed they will pay generously for a car whose story is complete, and they will discount any car whose story still needs explaining.
