I have just bought another Landrover (picked it up today) and will be doing around 2000 - 3000 miles a month in it. I have owned (well they were company cars before) 2 land Rover's before and my experience is that you could do with spending some effort to soundprooof it. The noise is the only thing that is a negative really, oh and the mpg is not too hot.
I have bought one with a few creature comforts as it will get a lot of use but essentially reduce the noise is my tip apart from the usual make sure you get a reliable one and maintain it properly.
