Historical icons and cutting-edge supercars went under the hammer last weekend at Broad Arrow’s 2025 Monterey Jet Center Auction, underscoring the diverse tastes and rising values within the collector car market today.
The top five sales at Broad Arrow’s Monterey Car Week sale ranged from timeless classics to such as the 1967 Ferrari 275 GTB/4 Coupe and the legendary 1955 Mercedes-Benz 300SL Gullwing to the rarified world of modern sports cars and hypercars.
The sales results are headed by a Maserati MC12 Stradale, which went for a winning bid of $5.2m, making it the second-most valuable Maserati ever sold at auction.
Cars from Koenigsegg and a Singer 911 were also some of the most valuable to cross the block.
Here are the five highest prices paid:
Estimate: $4.8m-$5.50m
Sold for: $5.2m (£3.84m)
A model-record sale for Maserati’s ultra-rare FIA GT1 homologation special.
The Stradale is one of just 50 MC12s built and based on the Ferrari Enzo platform. It sports a competition-purpose body and a V12 engine.
With just 11,500km from new, the MC12 became the second-most expensive Maserati sold at public auction, highlighting its significance as the ultimate modern Maserati collectible.
Estimate: $2.75m-$3.50m
Sold for: $3.22m (£2.38m)
Only 11 CCXR examples were ever made, and just three of those delivered to the US, making it rarer than almost any other hypercar.
The CCXR Targa is one of the first “green” hypercars, equipped with a 4.8L twin-supercharged V8 engine capable of running on both standard gasoline and E85 biofuel.
When using E85, the car is boosted to a staggering 1,018hp – performance that eclipsed rivals like the Bugatti Veyron at the time. Its technology was groundbreaking and remains world-class even by today’s standards.
With a top speed over 250mph and a 0-62mph time of well under three seconds, the CCXR Targa stands among the fastest road-legal cars ever built.
Estimate: $2.90m-$3.20m
Sold for: $2.64m (£1.95m)
Singer’s “Dynamics and Lightweight Study” (DLS) commission pushes the boundaries of the classic Porsche 911, pairing bespoke design and a 500hp naturally aspirated Williams-developed engine with exquisite craftsmanship.
The DLS is Singer’s most exclusive project to date, with only 75 examples planned worldwide. Each is a commissioned build for a discerning client, making every DLS unique in specification and details.
Singer partnered with Williams Advanced Engineering, tapping into Formula 1 knowledge to completely re-engineer the 911. The 4.0-liter, air-cooled flat-six engine is developed by Williams, revving to 9,300rpm and producing 500hp—absolutely remarkable for a naturally aspirated, air-cooled engine.
Estimate: $2.50m-$3.00m
Sold for: $2.56m (£1.89m)
The 1967 Ferrari 275 GTB/4 Coupe is celebrated as one of the crowning achievements of 1960s automotive design and engineering, highly prized by collectors and enthusiasts for several reasons.
Penned by Pininfarina and built by Scaglietti, the 275 GTB/4 represents peak Ferrari elegance with its long, flowing lines, prominent hood bulge, and rounded rear haunches. The proportions, detailing, and stance became the template for future Ferrari berlinettas.
The GTB/4 was the first Ferrari road car with a four-cam V12 (hence the ‘/4’), giving it higher rev capability, improved breathing, and a distinctive engine note. The 3.3L engine produces 300hp, delivering both thrilling acceleration and a top speed approaching 165mph – remarkable for its era.
Estimate: $1.90m-$2.20m
Sold for: $1.90m (£1.40m)
The 1955 Mercedes-Benz 300SL Gullwing Coupe is one of the most revered and collectible cars of the postwar era – an icon whose legacy looms large across automotive history, design, and engineering.
When introduced in 1954, the 300SL was the fastest production car in the world, capable of 160mph thanks to its 3.0L inline-six with Bosch mechanical fuel injection – a first for a production automobile. This made it as advanced under the skin as it was stunning outside.
Its most striking feature is the “Gullwing” doors, which lift up rather than outward. This wasn’t just for style – it was an engineering solution, dictated by the innovative but high sill space frame chassis. The end result became a styling icon, emulated by many but never equaled.
