A few different things to mull over here.

My wife drives an E46 325x, and it has been great. It is time to replace it next year, and it will likely be an E90 or an X3.

325 vs 330: 325 has good power, with the manual trans, IMO. We couldn't see any reason to take the 330 over the 325 when we bought. If we get an E90, it will be a 325x again, especially with the revised engine.

New look vs old: I like them both. Up to you, personal preference.

Buying a model with all the bugs out: always a good idea.
Buying the first year of a new BMW: more risk than waiting a year.

Resale value: Agree that the E90 will have more value, but it matters mostly if you plan to rotate it out again in 2 years or so. If you keep it longer than that, the differences blur.

Does fuel efficiency matter? If it doesn't matter now, it might matter a little more going forward. Who knows where the prices will be. That would be one of the things leading me to the E90 325.

Good luck, let us know what you decide.
