Looking for history on a vehicle

[shibby]

I'm doing a favour for a friend of mine, He's looking at the following vehicle. The current owner doesn't have alot of information on it, but said it used to belong to someone who worked at national 4x4. was just wondering if anyone knows anything about it.
