You may recall awhile back there was a green one floating around, up for sale in London.
It was very low miles, more than likely for the reasons stated above, and after being for sale for nearly a year, the price was down to a level where it became attractive (cheaper than a standard Plus 8).
At the time I looked into the cost of fitting a proper screen and a hood (which meant modifications to the rear deck), as well as side screens... needless to say, even having the work done by knowledgeable independent people with parts supplied by the factory, it was cost prohibitive (rear eye watering!).
