Just got my new R&T and there is an article on page 42 "BMW 328i vs. BMW 328i"
The E90 is a 08 and the F30 is 2012
The article does a great comparison between the two noting that they did not compare the 335 models because the 328 is "the one we'd buy with our own money"
The E90 they compare doesn't have sport package while the F30 does.
They note that the old cars interior feels a "full class more expensive than the new car's. And that's everywhere, from the switchgear to the center console to the glove box." noting that in the back the new car feels "rental-car grade"
This exerpt pretty much sums it up "Our decision was unanimous: We liked the old car better, if only by a slight margin. And later, when we hopped into a post-face-lift, Sport-package-equipped E90 328i, it was game over for the F30. No contest. "
So smile e90 brethren, and don't fret for that F30. Enjoy your ride!
