e90 330 is awesome! get it with active steering ($2000 option), well worth it.
i work at the bmw dealer btw. stop by if you want. it is a hell of a car for the money.
valvetronic is simply awesome. think vtec with infinite number of cam profiles.
get the i drive option too. cool system once you get used to it, and way better then the i drive on the 7 series.
