Need help with buying a used D600

[alim0h]

Hi everyone. I want to buy a used D600(4800 expos) which the owner claims she mainly used it for filming and stuff and never had any oil problem or whatever. She gave me the offer of 800euros for the body or 1100 euros for camera + 24-85 + 3 batteries and a bag.
With having in mind that a new D610 body costs 1350euros here and the kit with 24-85 costs 1840euros
I already have a D5100+18-105 and a good tripod and a set of speedlights , umbrellas and ....
I mostly shoot portraits and landscape.
What is your suggestion ? What should i check on the camera and lens when i meet up with her ?
I live in hungary by yhe way(im not hungarian though!)

Here in the US, a used D600 sells for $725 to $900.

Your 18-105 mm lens is a DX lens, for use on APS-C (DX) size image sensors.
The D600 has an FX image sensor, so the 18-105 won't fill the much larger than DX, FX image frame.

Nikon makes two 24-85 mm FX lenses with a $250 price difference, but you do not say which she is offering with the D600 nor which comes with the D610, 1840 euros kit.
Are the 3 batteries all Nikon batteries, or 3rd party batteries?

I just paid $670.00 total, shipped for a clean D600. It had the oil/dust issue. No worries, for Nikon already corrected it for free.
He shoots, he scores!
