As awkward as many feel the X4 is, myself included (though it's growing on me), the 3GT is worse. I would go 4 gran coupe over 3GT and I'm not even 100% sold on the 4GC yet (haven't seen one in person). We have a '14 X5 M sport and love the styling, it and my '13 335 (F30) are miles better looking than the 3GT. I had one as a loaner for a couple of days and it is great looking from the front but awful from every other angle.
X4 is growing on me. If the X5 is too big, I would say 435GC or X4, or even the new X1 when it comes out (not sure when that is or what it'll look like). I may actually take my wife's X5 for myself and getting her an X4 when my 335 lease is up. She parks on the street for work, so smaller car might make me cringe less when she takes it to work
