doesn't sound right, I'm a total top down sl*t, i drop my top every chance I get
done 7k no sign of wear. my 1 series on 22k, to 150k, had some very slight material crimps shall we say but NOTHING on that side
sounds like it's rubbing somewhere
I'd bet you only fix is a new roof or major component and there not going to swap a whole roof or top just for that
