If you're handy with a spanner then these things are a bit of a steal at the price point they're currently at. Most of the problems and issues with this model are quite well documented on the internet as well.
Mum had one around 2000 (I think, I was at secondary school anyway!) and she loved it, it was brand new at the time but since then I have always fancied owning one. I just can't justify a large 4x4 when I don't have kids, dogs or any mates
The air suspension, if I remember rightly, was a problem, but at the same time it was very comfortable. The petrols had head gasket problems, ours was a 4.6 Vogue but I don't think it was much of a problem on the diesels.
I think the diesel problem was 120bhp in such a heavy car, I'd definitely get a test drive, see what you think? I was only a kid but I'm pretty sure the body roll and pace means it'll never be anything other than a capable, comfortable tank.
Ours was blue, Oxford Blue I think it was called? My advice is test drive it and look for one with plenty of options to make it desirable to sell on, Harmon Kardon stereo was amazing, used to sit my mates in it and put awful scouse house on; I was about 15 at the time! Nav was available back then with TV i think.
I can't really offer much more! But I'll see you later to collect the projector!
