From the FAQ:

    Q: "I am confused as to why and how you got
    this, it seems like a mistake or fake?"

    Answer: As stated above apparently there was
    some miscommunication when the vehicle was
    decommissioned. It should have been offered to
    museums but the sales team did not know what it was. 

    They were told it was just a "Nasa vehicle" 
    they did not know it had any special status, 
    or history. To the sellers they thought it was 
    just a van that could have been for moving laundry
    around the base. It was an accidental (yet valid) sale.

    Q: "I see it says 025, were there 24 other vehicles?"

    Answer: Yes there were 25 other vehicles of different
    types and all of them were crushed and/or gone.

They continually emphasize what a foolproof and lucrative investment it is. As always, begging the question why don't they take advantage of the golden goose themselves?

Also, no photos of the interior, just renders is a joke.
