BMW's paint quality is not the greatest.
I got clear bra installed on my 335 and M3 right after delivery. On the M, I had rocker panels covered as well.
Also for those who are talking about repaint: -I would stay away from a used car where the entire front end was repainted. Good luck explaining to potential buyers that it was repainted due to rock chips & etc.
