I'd be interested in a group buy, if the price is right, although I don't know what color yet. These things look ten times better than overlays, which clearly look like stickers. Overlays are a good deal for the price though. Some of those color combo are sick.
I saw something similar, handmade in cloisonne at a show, but that dude had well over $100 in each emblem, plus wheel center caps too. It was really a work of art.
