About "it's too much of a monster already", I remember vividly 10 yrs back when I was accelerating full throttle to the speed limit of 120km/h with my E91 320d after a stop light. I guess it would have taken me about 12 seconds to get to 120 then. The cops behind me overtook me with full drama and gave me a ticket for reckless driving and they were really pissed because of my total lack of responsability!
