Umm . . . According to the Newtonian laws of physics on this planet, the F30 335i is lighter than the E90 335i. So the new car is not "bigger". This is as basic as it gets and only missed if you're just completely biased. At least the guy that brings up weight distribution is talking sense and has a legitimate opinion.
And by the above flawed line of questionable logic, then a Ferrari 458 Italia is no longer an 'enthusiast's' car because it is more dynamic in it's handling and more civilized than its predecessor. It's a silly argument since development always marches on.
