Jeramy,
You asked for opinions and mine agrees very much with yours. Tangibles like actual equipment, condition and factory documentation can have significant value to many buyers where intangible claims about originality, ownership, location, storage and even mileage may have little value to most buyers. In fact, when sellers make intangible claims about their vehicles, even if they have some means of verification, they usually limit their potential market if they try to use it to justify a premium asking price.
I also agree with Rob that seller's claims that are obviously incorrect because of visual evidence to the contrary or known false statements are a real turn-off to knowledgable and observant buyers.
As the Romans used to say: "Caveat emptor!"
