The car is obviously poorly engineered. I can only say that this is the worst underperforming car you could waste money on. Save your cash and buy a real exotic 'cause this ain't it. 36K and the transmission had to be replaced. The engine knocks like an AMC Pacer on unleaded gas. Burns oil like the forgot to install the rings. I will never own another MB after this beast is put to pasture. Oh, MB has denied that they are replacing 350 engines like there is no tomorrow. So much for Dr. Z and his nonsense. He should make the remaining payments. The car is listed at 268 HP; no way it develops 268, more like 200, maybe. My Z4 could blow the paint of this beer can.
Looks are it. If you want a poser vehicle, spend away. If you want performance I suggest you take another look, elsewhere.
Buy the 500 engine version. The car is a waste of good money.
