Put E9x on your freaking signature/avatar folks
. We have to be guessing which darn car you're talking about
.
No issues at all with either window rattling or tint marks on my coupe. But yes, it has many other noises
. By the way, window is not going to rattle if fully closed or open, so just keep it in one of those positions and problem solved. Or if really loose, it doesn't have to be tightened to hell. Again, maybe sedan is different, but no such problems on the coupe. If it's a coupe, just get it tightened to where it should be. I'd obviously do that myself, but if you want a dealer to do it, make sure they have another M3 to do it right. Good luck.
