In 2003, Mercedes-Benz dropped the proverbial H-Bomb on the German horsepower war in the form of the Bi-Turbo, 5.5L V12 for the top 600 series CL and S Class cars. Not only did the V12 match their own all-new 55 AMG Kompressor with the exact same 493hp rating, but it added a 590 lb-ft mountain of torque that left competitors like the 394hp/368lb-ft BMW M5, the 438hp/444lb-ft V12 BMW 760, and even the vaunted 450hp/415lb-ft Bi-Turbo Audi RS6 seem like tinker toys by comparison. The CL600 seen here is an immaculately-kept example. In addition to the glut of standard features like heated/massaging/ventilated seats, GPS Nav, premium Nappa leather upholstery, xenon headlamps, 10 airbags, etc., etc., it has the optional Power Trunk Closer and Nav CD Collection. Original MSRP: $127,935. This CL has a clean CarFax, brand new tires on upgraded later model 20-in AMG wheels, and has gone through our 71-point inspection process. It is a superb value, and if you told people you paid $100k, they would likely believe you.
