RM Sotheby’s will offer the final Mercedes-Benz SLR McLaren Stirling Moss ever built through its Sealed sale this month. The 2010 speedster shows 32.9 miles and carries an estimate in excess of $6 million.
The last one built has barely moved
Seventy five cars made up the full Stirling Moss run, and this 2010 example closed it out as number 75 of 75. Its odometer shows just 32.9 miles, a reading closer to delivery mileage than to any real use on the road. Nothing else in the run follows it here.
The Royal Family of Kuwait originally commissioned the car, and it then sat in climate-controlled storage in Switzerland until 2024. That long stretch indoors covers most of the car’s life, and it explains how a speedster from 2010 reaches the block looking barely touched by time or weather.
Final examples carry a weight the rest of a run can’t match, because a production story needs an ending and this car is that ending. Buyers aren’t just bidding on condition here, they’re bidding on the last chassis the Stirling Moss line ever produced.
The 32.9 mile reading also freezes the car in a particular state, closer to its factory finish than to any life spent on the road. Every future mile changes that story, so the next owner inherits a genuine decision alongside the car itself.
Fire Opal Red and a cabin built around one commission
Fire Opal Red covers this car alone, since no other Stirling Moss left the factory finished in that particular color. The cabin follows the same brief, with Silver Arrow red leather inside and contrasting yellow stitching running through the trim panels. One color, one cabin, one original buyer.
The front seats sit wider than standard, the interior trim uses Alutex aluminum, and the detailing keeps pulling the eye back toward that single original order. Every choice here traces back to the commission rather than to a catalogue page, and that specificity is exactly what collectors chase in a final example of any limited run.
Red over red could have tipped into excess, yet the yellow stitching breaks the cabin up and keeps the whole specification legible at a glance. The widened seats add the practical note, a quiet reminder that somebody ordered this car intending to actually sit in it.
No roof, no windshield, no side glass
The speedster layout drops the roof entirely, drops the windshield, and drops the side glass, leaving two small wind deflectors ahead of the seats. That shape reaches straight back to Sir Stirling Moss and his 1955 Mille Miglia winning 300 SLR, the car this edition honors. Exposure is the whole design brief here.
Carbon fiber bodywork wraps the whole car, and without glass or a roof the body lines run uninterrupted from the nose to the tail. Rain stays the owner’s problem, wind stays a constant companion, and neither concern has slowed interest in the model over the years since.
Most modern performance cars seal their occupants away from weather and noise, then simulate involvement through screens and speakers and synthetic sound. This one skips the simulation entirely, and the little deflectors offer token help at speed rather than any real shelter from the wind. The brief never included comfort, and the car makes no apology for that omission anywhere in its design or detailing.
A supercharged V8 with nothing overhead
Under the carbon fiber bodywork sits a Mercedes-AMG 5.4-liter supercharged V8, and it makes 650 horsepower in this particular application. The sprint from 0-60 mph takes 3.5 seconds, and the top speed reaches 220 mph, figures that still read as serious today. The performance numbers still hold up today.
However, the open cockpit changes how those numbers land, because there’s no roof panel and no windshield muting the speed once it builds. A closed car at 220 mph feels filtered and distant, while this one puts its driver directly in the airflow the whole way.
Supercharging gives the V8 its character, with boost building under a long hood that dominates the car’s proportions from nearly every viewing angle imaginable. Sixteen years on, those figures still frame the car as a serious performance machine rather than a static collectible gathering dust.
Power reaches those speeds through a body that leaves its occupants exposed, and that pairing defines the Stirling Moss more than any single figure. Few cars at this level ask so much commitment from the person behind the wheel.
The only one America can register
G&K Automotive Services fully federalized the car and completed its US road registration, making it the only road legal Stirling Moss example in America. That status changes the buyer pool considerably, because the winning bidder can actually register and run the car on American roads. That legal status sets it apart completely.
RM Sotheby’s runs the Sealed auction from November 25 through December 2, 2026, and the estimate sits in excess of $6 million. Its cabin still carries the integrated stereo, a fitting oddity for a car pairing delivery mileage with a seven-figure estimate. Sealed bidding keeps the process private, and the final result lands only after December 2 closes the sale. A car this specific rarely needs a crowd, since the shortlist of buyers for a seven-figure speedster writes itself.
