Re: What shape was it in?
I was at the after-party in Cape Canaveral when Elon returned from inspecting the landed rocket. He told us "it is in such good shape, we could re-fuel her and send her up again!" So very little "re-furb" would be required - that was the whole goal.
The next day, however, Elon told reporters that he probably will NOT re-launch the Falcon 9, only because of its "historical signifigance." He probably wants to save her for a museum etc.
