Only crazy CL600 M275 V12 like this that has ever known to exist.
Used to be the World’s First rear mount turbo m275 cl600 but this is so much more efficient.

Hahaha at first I was like what!?

Issit a good learner vehicle

What do you mean? Like good learning platform or is it easy to work on?

My dad would PDI these when they were new. He told me about taking one around an old, mostly abandoned industrial estate about a mile away from the dealership (housing estate now) and it was raining. Him and a mate did doughnuts etc there in one, and according to him, that a W220 S600 and W220 S65 are some of the worst cars he’s ever driven in the rain

Haha I believe it! I got caught in very bad rain / standing water on a highway outside of Albuquerque NM (on my trip across the country 2 years ago) and I thought I was actually going to die. Granted I had Toyo R888’s on…but at 60 on highway between and around semi trucks and I was hydroplaning every where and losing traction. These new non radials seem to be able to shed water much nicer. but yeah with all that TQ it likes to kick out.
