These covers are beautiful and very well cast and finished. Mine came wrapped in Chinese/Korean newspaper, so no hiding where they were manufactured if thats a concern. So nicely finished that only usual prep was needed to paint them if that's what you want, but so nicely finished that they look great naked. The only slight issue was that in my stock caddy engine bay they require the generator to be pushed out quite far to avoid it hitting the covers. You may have to experiment with a slightly longer belt.
