I need to replace a panel on my drivers seat. I have the dark gray (agate) leather interior. The guy at the local upholstery shop told me that it was a discontinued item and the best he could do was a vinyl patch. I already tried that and am not wasting my money on that route again. I really love the look of the interior with this leather and do not want to go changing anything else. Did I just get one lousy shop or is there really not an availability of this material?
