Well I paid massively over the odds for mine £3.7k, but it has no rust at all and had 41k on the clock which I could track back in the UK and Japan.
Still had leaks in the sunroof though.
Since then I have done some work on mine i.e. a full service of everything I could possibly think of, it does 33mpg on a run not bad for an auto and whenever I get a Snorkel to fit it (ABS bugger, everything else including a full rack, under body protection, wading kit, rock and tree sliders, cb, cooker etc) I will have spent a total of 6k on an overland prep car with 46k on the clock now. Thats about a rusty 110 Defender 300TDI.
I think its ok because the other choices would have been to get the welder out, or buy something which could not be fixed in Morocco if and when it goes pop. Mind you the Aircon has given up :-(
Mind you that is f1ng expensive, I guess its shiny though.
