This past week delivered particularly active auction activity on both sides of the pond, across RM Sotheby’s and Bonhams in Monaco, Broad Arrow Auctions Air|Water in California, Bring a Trailer, and duPont REGISTRY Live online, producing strong results across historic icons, modern hypercars, and analog driver-focused builds.
Leading the results, RM Sotheby’s Monaco delivered an eight-figure sale with a 1961 Ferrari 250 GT SWB California Spider by Scaglietti selling for €16,655,000 ($19,529,784), a new record for a non-competition example. The result extends a consistent run of strength for blue-chip Ferrari open-air classics, surpassing comparable sales of the model earlier this year at Rétromobile, Paris for $16,727,110 at Amelia Island Auctions for $16,505,000 and a LWB California Spider result at Moda Miami for $7,045,000. The final figure lands meaningfully above the car's current duPont REGISTRY Index (dRi) value of $16,800,000.

Modern Ferrari flagship models were also well represented in Monaco, led by a 1-of-9 Argento Nürburgring 2004 Ferrari Enzo at €6,530,000 ($7,657,129), a track-only 2018 FXX-K Evo at €5,180,000 ($6,074,108), and a 2014 LaFerrari in a 1-of-1 Signal Green at €5,067,500 ($5,942,190). A Classiche-certified F40 closed the group at €4,336,250 ($5,084,720), maintaining strong demand for analog-era Ferraris with verified provenance.
Across the broader Monaco sale, results showed strength across multiple segments of the collector market. Historic competition cars such as the Porsche 550A Spyder and Ferrari 312 T3 traded alongside modern hypercars like the Bugatti Bolide. Rarity, competition history, and factory specification continue to define pricing at the top end. Overall, the RM Sotheby's Monaco sale delivered €87,967,385 million ($102,929,470) in total sales, setting a new benchmark as the highest-grossing multi-car auction in Europe.
Bonhams Monaco delivered steady results, led by a 2021 Lamborghini Sián at €2,012,500 ($2,358,523) and a 2019 Aventador SVJ at €563,500 ($660,385). The event recorded an 83 percent sell-through rate and €10,385,907 ($12,178,596) in total sales, reflecting consistent demand across modern supercars and collector-grade classics.
Broad Arrow Auctions delivered one of the week’s standout modern results with a 2025 Gordon Murray Automotive T.50 selling for $8,035,000 in a single-car auction in Paso Robles, California. Separately, the Porsche Air|Water event in Costa Mesa saw multiple seven-figure results, led by the only paint-to-sample Riviera Blue 2015 Porsche 918 Spyder Weissach at $4,680,000, well above its duPont REGISTRY Index (dRi) of $2,700,000.
Modified and specialist Porsche builds also performed strongly, including a 2025 RUF SCR at $2,095,000 and multiple Singer reimagined 911s surpassing seven figures. Demand continues to remain concentrated in low-production, high-specification restomod and tuner-built cars. Broad Arrow's 2026 Porsche Air|Water auction realized total sales of $20 million with an 84 percent sell-through rate.
Bring a Trailer added further evidence of analog transmission-driven value, with a 2003 Lamborghini Murciélago 6-speed selling for $680,000. This follows last week’s stronger duPont REGISTRY Live result for a 1-of-26 factory-gated Murciélago that had a hammer price of $778,000. It highlights the premium and interest attached to curated enthusiast-focused platforms for rare manual examples.
Ferrari’s gated manual market showed a similar dynamic. A 2006 Ferrari F430 Spider 6-speed hammered at $377,000 on duPont REGISTRY Live, while another example brought $376,000 on Bring a Trailer. Both cars were nearly identical in specification and presentation, with only minor differences such as wheel configuration separating them. Pricing still varied by platform and presentation, reinforcing sustained demand for factory manual Ferraris.
Across both Ferrari and Lamborghini markets, factory manual transmissions remain a distinct valuation tier above automated manual cars and aftermarket conversions. This premium is largely driven by scarcity, as both brands no longer produce or offer manual transmissions in their current lineup.
Taken together, this week’s results reinforce a familiar pattern: the market continues to reward rarity, strong specifications, and enthusiast-focused appeal across both modern and legacy performance cars.
This trend was also reflected on duPont REGISTRY Live, led this week by a 1997 Porsche 911 Carrera Speedster by Gunther Werks that crossed the digital block at $910,000.
The following highlights break down the individual sales that best illustrate these broader trends.
Market Highlights

1961 Ferrari 250 GT SWB California Spider
RM Sotheby’s Monaco - €16,655,000 ($19,529,784)
This 1961 Ferrari 250 GT SWB California Spider by Scaglietti (#2955 GT) remains among the most desirable open-air Ferraris ever produced. One of only 39 examples (this is the 26th built) originally configured with covered headlamps, it is powered by a 3.0L Colombo V12 and paired with a 4-speed manual transmission, it combines competition-derived engineering with timeless coachwork. Finished in a Blu Scuro with a red interior and accompanied by the rare silver hardtop and extensive documentation including the Ferrari Classiche ‘Red Book’, the result landed close to its $16.8M dRi benchmark. At this level, the market continues to be defined by blue-chip scarcity, long-term collectability, and historically significant configurations that rarely trade.

2025 Gordon Murray Automotive T.50
Broad Arrow Auctions - $8,035,000
The Gordon Murray Automotive T.50 continues to establish itself as a benchmark for modern analog supercars. Powered by a naturally aspirated 3.9L Cosworth V12 revving to 12,100 rpm and paired with a 6-speed manual transmission, it emphasizes driver engagement over outright performance metrics. Offered with just 27 testing and delivery miles and representing a limited production run of just 100 units, this rare U.S.-market example highlights its position at the very top of the modern collector segment.

2015 Porsche 918 Spyder Weissach
Broad Arrow (Air|Water) - $4,680,000
This Paint to Sample Riviera Blue 918 Spyder Weissach was delivered to North America with a black interior and silver piping. It significantly outperformed its $2.7M dRi benchmark, highlighting continued strength in early hybrid hypercars that make up the holy trinity along with the La Ferrari and McLaren P1. Optioned with the $84,000 Weissach Package and over $7,000 in Exclusive Manufaktur CXX tailoring, the car shows under 1,300 miles at the time of cataloging. Powered by a 4.6L V8 paired with dual electric motors for a combined 887 horsepower, it represents one of the most highly specified 918 Spyder examples to come to market in recent activity.

1997 Porsche 911 Carrera Speedster by Gunther Werks
duPont REGISTRY Live - Hammer Price of $910,000
This Gunther Werks Speedster is a top-tier interpretation of the air-cooled 993 Porsche platform. Handbuilt in Huntington Beach California, with extensive carbon fiber bodywork and a naturally aspirated flat-six paired to a manual transmission, the build shows just 1,084 miles at the time of documentation. Finished in Amethyst Metallic over a bespoke purple-and-black leather interior, it sits firmly in the upper tier of the Porsche restomod scene. A limited production run of just 25 examples and meticulous execution continue to define values at this level, where craftsmanship and engineering integration now rival originality in importance for collectors.

2006 Ferrari F430 Spider
duPont REGISTRY Live - Hammer Price of $377,000
This Nero on Beige Ferrari F430 Spider features the increasingly sought-after factory 6-speed gated manual transmission paired with a 4.3L naturally aspirated V8. As Ferrari shifted toward automated manuals during this era, true factory manual examples remain exceptionally scarce. Alongside a comparable Bring a Trailer result at $376,000, this sale reinforces the clear premium attached to factory analog configurations, where transmission choice remains one of the strongest differentiators in modern Ferrari valuation.
