Mine's on a J without Air-Con or leather but I'm not that fussed [It was only £400

]
My neighbour has a 520i SE with Air-Con and no leather which he gave £600 for [about 140k].
The one you've posted seems a little dear to me...plus it doesn't list the mileage which probably means its been to the moon and back. And its an Auto which I personally wouldn't have.
You usually find th 2.5 is a little cheaper as nobody wants the big engine model but mine is 'Ok' on fuel
The other adavantage is its RWD...don't think the Rover is, is it?
