No worries, its a great looking car anyway. I would doubt it will go any lower TBH - but lets hope!
I remember when I got mine new last year and it seemed as low as my previous E90 2006 330d M Sport when I picked it up, from what I remember.
It doesnt bother me that much (as a possible F30 purchaser) however, as someone mentioned in another thread, if it starts to affect body roll - than that
is disappointing.
In fact, here's what mine looked like the day I picked it up. Not great pics though, but I dont think it looked any different to today.
