Unimog price advice?

[SmokinV8]

Hi all. I have been offered by a supplier of mine a Unimog that they have working on their farm, and Im interested but have no idea about its value. Its a 1981 1000 with 6250hours of use on it. Any ideas of value or potential pitfalls in this vehicle? As a price guide I was told about £4500.
Any help appreciated, Neil.
