Joe most of the sites of the type you posted are really just distributors. They have no clue what is and what isn't a limited edition spoiler. Just went through a fiasco with automotix about ordering limited editions and they sent me stock spoilers. They had never heard of a limited edition spoiler, yet advertised that they were selling them. I had to post pictures and go through a bunch of hassle to get my money back.

Edit: Now also looking for an F1 hood
