Second upgrade this year....but something weird

Hello again,
I came back from one shop with a new body to my list.
I didn't open the box yet here at home, but as first glance in the shop, the box seems was opened before, the manual is not original at all, it is a photocopy printed out, i don't know what else there i didn't check, i told him don't take everything out, only the body and i assure the letter X is there. On my way back, a salesman called me and told me there is the eye-cup missing, i don't know what he means, but shouldn't that be on the body or at least it is inside the box? What's going on?
How can i be sure now that this body is new BRAND NEW? before i open the box i want to know your opinions about it.
How can i make sure about the shutter counts so at least to feel this body is really new and not used before or opened or even for demo, any clue?
