I know this is an old post, however if anyone is still looking for a carbon fiber trunk lid I offer the VIS Racing Carbon fiber trunk lids (Hoods also) for A4 02-04 trunk lids start at $720 plus shipping for OEM Style. I am also willing to do work with the price for members. Hope this helps someone out.
