About to buy my first AP royal oak but needed advice from you guys...

[Stonedcl]

I found a AP 25594ST 36MM moonphase watch locally and I am very close to pulling the trigger on it. The owner said they bought it about 5 years ago but never had it serviced and hardly wore it. IT looks mint in the pictures.
It has a white face.. They are at $7000 and are willing to meet me at a AP so I can have it authenticated before handing over the money. Is $7K a fair price for this watch, I see others on Ebay and chrono24 for 8-10K and they look alot older. This watch has the AP clasp with the AP letters so the clasp is AP not the rectangle clasp that alot of them have. How much would it cost to have this movement maintained at AP service center? I tried on a 39MM AP and it was a little too big so I think this 39MM would fit perfect..
What do you guys think about the price and the movement in this watch..
For 7K would I be able to recoup me money if i did not like it and wanted to flip it?

Thank you!!
