Only 25 were built.
Back in 2003, Mercedes-Benz and McLaren teamed up to create the SLR, long before the Mercedes-AMG developed its own in-house sports cars like the SLS and GT. Created as a modern-day tribute to the 1950s Mercedes 300 SLR racer, 2,157 examples were built between 2003 and 2009.
As Ed Bolian recently found out, owning an SLR isn't cheap as the service costs are astronomical. Bolian paid $180,000 for Paris Hilton's SLR, but this example for sale in Germany is even more special and expensive. Not only is this SLR the more desirable 722 variant, but it's also one of 25 examples that were modified by McLaren Special Operations.
When the SLR was launched, Mercedes owned a 40 percent stake in McLaren. The SLR was discontinued after the two carmakers parted ways, but McLaren Special Operations gave the sports car a special send-off. The result was the SLR McLaren Edition.
To distinguish it from the regular SLR, MSO fitted an aerodynamic body kit that added new front and rear bumpers, a unique grille, a new hood, and a more aggressive diffuser. It also sits on unique wheels and features a titanium exhaust system. Mechanically, MSO upgraded the steering and suspension setup and fitted new ceramic brakes to improve the stopping power.
MSO's extensive modifications reduced the SLR's weight by 110 pounds while increasing the downforce by 20 percent. Under the hood, MSO left the 5.5-liter V8 stock, but 722 variants have an increased output of 641 horsepower and 605 lb-ft of torque, enabling the SLR McLaren Edition to sprint from 0-60 mph in 3.6 seconds and max out at 209 mph.
This example listed for sale in Germany is number 12 out of the 25 SLR McLaren Editions built. At the time, the upgraded SLR will have set you back $205,615, but this example is selling for an eye-watering €2,600,000 ($3.1 million), making it more expensive than a Bugatti Chiron.
