I'll throw my hat into the ring for the Defender. Landie jokes aside, when talking standard 4WDs there's not much that can compare to a Deefer. All the options (inc mud tyres, winches, bars, etc) are all factory options. Small TD motor should help appease the bean counters. Big enough cargo are to haul all the gear you may or may not need.
Of course, I've got no idea what the standard safety spec for a Defender 110 is these days. I believe they have ABS, but no idea if you're talking Traction Control, or any of the fancy Terrain Response that the Disco gets. All I know is that I've seen the video of the fancy anti-stall system working, and it looks idiot proof.
I'd be tempted by the 200GX, simply because of all it's fancy electronics.
Good luck with whatever you can convince the Powers That Be you need!
