It's behind you
My E220 is a peach, a teeny bit noisy on startup but after that it settles down and is lovely and quiet. Power is nice and smooth, i was worried before i bought it that with the weight of the car nearly 170bhp wouldn't be enough but i don't drive like an idiot (which is why i didn't buy a BMW) and am very happy. In the real world the power is more than enough.
