Actually I need to replace the upper grill, too, because the plastic guide that holds the hood release is also broken. I thought instead of direct replacement I'd go for piece from S6 or A6 4.2. The only thing that's holding me back is the matt aluminium trim the regular grill came with. I'm wondering whether I can detach the trim and retrofit it to replace the chromed surround that comes with the S6/A6 4.2 grill... More uniform look, I suppose.

As for the mirrors I've only looked at OEM stuff. But anyway, what you're getting is a primed but unpainted mirror case. So you'll need to find someone to color-match the paint. VAGPARTS.COM is offering $73 for a set. My local stealer wants $75 per side.
