Just from the little bit that you have said and other comments from this board, its looking more and more clear that a E9x would suite me better. I do tend to like the styling of the E90 models more, in the front anyways. Something about the headlights and front bumper on the F30 that just looks off to me.
Realistically i would have to wait another year or more before the prices come down on a F30 where id feel comfortable spending that much, considering a mortgage will be following soon as well.
But definitely will give both a shot.
