Well after driving them both for awhile (as loaners) I have to admit I like the F30 328xi more than expected and 30+mpg is well within reach (unlike with the X1 with same powertrain.) I'd consider paying the premium for an F31 wagon vs. the X1... Many bits are a notch nicer- nice interface that comes w/o navi is pretty cool and seems well integrated but no std camera with it? That said I definitely wouldn't consider it a sports car (never was w/o an M badge) and not sure I'd put it in the sport sedan class either anymore- at least not without some sort of sport suspension packaged on. If its a sports car you're after and you want a BMW, you need to change your order to an E82 1 series, quick while you can
... I kid, F30 is a nice car with a way better interior than the former but it is less engaging, much less so than my E82 even though it may be a tick or 2 quicker.
