Car and Driver:
"While we haven't had the chance to drive the new 2-series yet, preemptively we think the rear-drive 230i is the one to buy."
Based on your location, that statement may speak to you.
HUD would mean little to me as I have never had it, if it is that important, wait for it to come back.
The weight difference between the 230i and the M240i xDrive is very significant.
