A 2008 Mercedes-Benz SLR McLaren roadster with a twin-turbocharged V8 engine and numerous other upgrades is being auctioned on Bring a Trailer. The vehicle, which has 12,000 miles on the odometer, features a carbon-fiber body, butterfly doors, carbon-ceramic brakes, and a high-end Bose sound system. Originally delivered to California, the car has since been modified and imported to British Columbia, Canada.
Why it matters
The SLR McLaren was a limited-production, high-performance sports car developed through a partnership between Mercedes-Benz and McLaren. This particular example has been further enhanced with a twin-turbocharger system, making it an even more exclusive and powerful variant. Rare modified supercars like this often generate significant interest from collectors and enthusiasts.
The details
The 5.4-liter V8 engine originally featured a supercharger, but this has been replaced with a Weistec twin-turbocharger system. The car also has a high-flow exhaust and air filters. Power is sent to the rear wheels through an AMG Speedshift R five-speed automatic transmission. Other modifications include carbon-ceramic brakes, 19-inch alloy wheels, and a Bose sound system. The roadster is finished in Pure Black over a Silver leather interior.
- The supercharger was removed and replaced with a twin-turbocharger system in October 2022.
- The differential fluid was changed in October 2022.
The players
Weistec Engineering
A California-based automotive tuning and modification company that performed the twin-turbocharger conversion on this SLR McLaren.
What’s next
The judge in the case will decide on Tuesday whether or not to allow Walker Reed Quinn out on bail.
The takeaway
This rare and extensively modified Mercedes-Benz SLR McLaren roadster represents an exciting opportunity for collectors and enthusiasts to acquire a unique high-performance sports car with significant upgrades over the factory model.
