Dang, something else to worry about. I've been very gentle with mine, more or less easing it down, but I guess I'll really give it a gentle touch, now. I'm still not putting on the straps I have in a drawer until I need to do something else that requires tearing off the roof.
Anyone have a tear in their headliner? I found a little tear in mine on both sides that must have been there all along and I just never noticed. I'm debating trying to stitch it up in-place, or maybe putting some little roundels or M patches over it...you know, since the Z4M has so few M's on it.
