F30 looks amazing, even with the stripe. That front splitter really sets it off.
The 1er looks odd, far too hamann like to me, especially the front end.
5er is ok-ish. Don't think these performance parts suit the car. I think M sport trim is the way to go (if you can't afford an M5 of course!)
Interior spot on!!
And that concludes my first ever bimmerpost comment!
