Thanks for the information - yes it does feel very quick...this morning, approaching my place of work, I had to change lanes rather quickly because a car braked without warning (turning right and no indicator!)...I changed lanes and accelerated without realizing how quick the car was. As a result I overshot the entrance to my office building, and had to make a U-turn...shows me I'm slow in not shifting my mindset from my '97 Camry, which I traded in for this head-turner.
Since this is my first Merc (I'm 26), I am not sure if I should drive in D or 4. What do you suggest (I love this forum very much, since people are full of kind words and advice without being condescending

)
Best regards,
Sesh
