I'm not gonna come out and throw them on the burnpile but do your research, they have no qualms about selling fake items (including cars) as long as they get their cut. All you are going to get is a short description, if you don't see the documentation you can assume it isn't real. A classic example is the upcoming Eddie Vannoy road art collection, never seen so many fantasy/fake items put out there although there are some real items mixed in, mostly restored pumps.
