Personally, this is what I would say, and this is just MHO. I have viewed at least 6 of their cars advertised (not in person, just online), and have found their descriptions to be lacking honesty. Maybe they don't know, but I seriously doubt it. Take the lack of tach issue. That's been done by them before, so seeing it is nothing new. Does that mean the entire cluster has been swapped? Maybe, maybe not. Them not mentioning anything about it is kind of shady, especially since they claim to know Mercedes Benz'. They tend to throw a cheap paint job on there, as evidenced by lack of something as simple as masking, put one of their "car killer" kits on there, and sell for 7-13k. Not bad business, but I couldn't do it myself. I'm not into screwing my fellow American for profit.
