This M120 6.0L V12 drivetrain is sourced from a 45k-mile 1997 Mercedes-Benz SL600 (VIN # WDBFA76FXVF146565) and was removed from the car in 2022. The 6.0-liter M120 V12 was factory rated at 389 horsepower and 420 lb-ft of torque from the factory when new. That power is translated through a 722.621 five-speed automatic transmission. Both the engine control unit and the transmission control unit with crank position sensors are included with the sale allowing for easier installation into a new chassis or project. This M120 powerplant is now offered with NO RESERVE by the seller in Southhampton, NY with compression test results, borescope video footage of the cylinder walls/engine internals, ECU/TCU, exhaust headers, factory accessories and may be picked up locally or crated for shipping.
The 1997 SL600 donor vehicle was a clean title, accident-free example prior to the smoke damage and the R129 was reportedly not directly impacted by any resultant fire or water. The garage where the vehicle was housed was reportedly a separate structure on the property adjacent to the home so, as a result, there was no direct water or fire contact with the donor vehicle.
A video of the powertrain being turned over as well as some borescope footage is viewable below.
