It looks pretty much the same as an E90 just with the new corporate nose grafted on, side profile is virtually indistinguishable.

from the front wheel arch back, the car looks extremely similar to the E90 LCI. The rear of the F30 looks very similar too.
I must admit, i quite like the layout of the new interior though. Apart from that, a rare-as-rocking-horse poo E90 330i LCI or 335i isn't much different from an F30 328i at all, bar the front end and slightly better MPG figures..
Only one left now.
