Have only had the E350 Coupe a few weeks cant believe the amount of bonnet stonechips i have got in such a short time, the previous couple of BMW i had , 1 & 3 series only had the odd one , the wifes 05 Golf has not got any and thats from new !! . Dont know what looks worse just leave them or try touching them in, got some some touch up paint ( iridium silver ) but that has only made the chips more visible
