I recently bought a 5D mark III in Sydney - I just love it!
The retailer (an authorised dealer) offered it at what was a good price at the time although I suspect that the unit had been used as a 'showroom' unit for a little while, because when I took it home and put a brand new memory card in it, the sequence number was around 1400.
That may or may not be the actual shutter count - possibly a card used in another camera had been used by the shop to demo the camera.
I tried EOSinfo (had good results on my older 50D) - but it didn't work with the 5D III (PC, Windows 7 64-bit)
Does anyone know of a method to find the actual shutter count on a 5D Mark III?
