Thanks for the review jaehshim.
I feel we are on the same page when it comes to comparing the e90 vs the f30. I wasn't impressed with the physical steering wheel. It seems to be "plastic" compared to a nicely wrapped leather. Suspension didn't feel as tight unless you switched to sport mode in which just gives you higher RPMs. Did it change anything else? I don't think so.
Also there were 7 gears if I'm not mistaken.
Very lovely car but I wasn't sad at all getting back into my e90 335i.
