I just got a 2013 BMW 328xi Sedan AT, Estoril Blue, Black interior, M-Sport/Premium/Tech/Cold weather packages. I paid $49,750.
I agree with all your statements it is a great and fun car to drive. I haven't filled up yet only had it for just under a week but the instant mileage is telling me 26.3mpg so far. I don't put it in sport mode too much yet and have been using the ECO mode after I'm up to speed and cruising.
