I would think that caliper color can also be changed easily, it's the painted stripe, and what appears on the invoice that are the more difficult items to "alter". Another question would be how many of these are non salvaged? Since becoming an owner, I've heard all kinds of stories as to how many cars were hit and never reported through insurance, etc. Yes when buying through someone like Shelby, you're going to be comfortable with knowing it's a "clean car", other than that, obtaining a PPI from someone who knows what they're doing is a necessity!
