At 7:22 a.m. on 1 May 1955, Stirling Moss and Denis Jenkinson launched their Mercedes-Benz 300 SLR from Brescia into the Mille Miglia, the grueling 1,000-mile race across Italy. Ten hours, 7 minutes, and 48 seconds later, they crossed the finish, averaging an astonishing 97 mph—an achievement that remains the fastest run in the event’s history. Their car bore the number “722,” a simple departure time that would become one of the most evocative symbols in Mercedes-Benz lore.
More than fifty years later, on 28 September 2006, Mercedes-Benz and McLaren revived the legend at the Paris Motor Show with the debut of the SLR McLaren 722 Edition. Limited to just 150 hand-built examples, each crafted at McLaren’s Woking facility, the car fused Formula One expertise with AMG’s powerhouse engineering to create a modern tribute to Moss’s immortal drive.
Broad Arrow Auctions is proud to offer an exceptional example of the 722 Edition at its Las Vegas Auction, held at the iconic Wynn Las Vegas in partnership with the prestigious Concours at Wynn Las Vegas.
Under the long carbon-fiber hood sat a hand-assembled, supercharged 5.4-liter V8 producing 641 hp and 605 lb-ft of torque. The performance was ferocious. From a standstill to 60 mph takes just 3.6 seconds, while it rushes to a top speed of 209 mph. Quicker shift programming, stiffer springs, revised dampers, lightweight forged 19-inch wheels, and massive 15.4-inch carbon-ceramic brakes with red calipers elevated the driving experience with sharper turn-in, greater stopping power, and heightened precision.
Aerodynamics and weight savings completed the transformation. A deeper front splitter, functional diffuser, and deployable airbrake enhanced high-speed stability, while the carbon-fiber body shaved nearly 97 pounds from curb weight. Inside, darker finishes, embroidered “722” insignias, and sport seats underscored its exclusivity and racing inspiration.
The lineage expanded in 2007 with the SLR Roadster, its carbon-fiber monocoque preserving strength and safety despite the absence of a roof. The soft top could be raised or lowered in under ten seconds and maintained refinement even past 124 mph. By 2008, the SLR McLaren 722 S Roadster pushed the concept further—an open-air supercar retaining 641 hp, sprinting from zero to 60 mph in 3.7 seconds, and reaching 209 mph. With sharpened suspension, aerodynamic finesse, and styling cues worthy of its heritage, the “722” name was carried into a new era of uncompromising performance.
Of the 150 722 S Roadsters produced, this example is one of only a handful sold new in Canada. Finished in Crystal Galaxit Black Metallic, the interior was specified with Black leather and Alcantara, contrasted with red stitching, seatbelts, and binding on the carpet floor mats. The largest body-contoured seat options, including the “XXL” driver’s seat and the extra-large passenger seat were specified for added comfort and convenience. Additional equipment for this Roadster includes an Anthracite power-folding soft top, dual-zone automatic climate control, a six-disc CD changer with a Bose sound system, and 19-inch multi-spoke alloy wheels.
The accompanying clean CARFAX Vehicle History Report shows that the car remained with Canadian owners until it was imported to the U.S. and “declared to meet U.S. highway safety specifications” on 27 November 2024. Before its importation, in November 2021, the car received a large service by Mercedes-Benz Boundary of Vancouver, British Columbia, that included a brake fluid flush and replacement of the hood struts, engine oil, spark plugs, and serpentine belt at 7,915 kilometers.
Set to be offered at Broad Arrow’s inaugural Las Vegas Auction on 31 October 2025, this superb example of the SLR Roadster 722 S was acquired by the present owner in January 2025 and has remained in outstanding condition ever since. With only 5,290 miles recorded at the time of cataloging, it reflects minimal use and careful stewardship. The Roadster 722 S marked the pinnacle of the SLR program, blending the engineering precision of McLaren with the luxury and innovation of Mercedes-Benz. Its distinctive styling, motorsport-derived performance, and limited production have made it one of the most sought-after modern supercars. Presented in an exceptional color scheme and showing remarkably low mileage, this example offers a rare opportunity to acquire a car that captures the very essence of exclusivity, performance, and design.
