Cheers guys, thats all really helpful stuff. It is the green one that I was interested in. It appears to be the only one he has got left. From what I understand he (Clive) has stopped dealing in them now and has moved on to selling alfas.
I will try and go and have a look at it this week if I can - the low mileage is an attraction but by the same token I know thats no guarantee of reliability (I'm assuming the isuzu engine is pretty good in that respect it would be my only vehicle so reliability is a bit of an issue for me) but it seems to be commanding a very hefty premium £1500 to £2000, which presumably is nearly a months worth of fuel for one of these things!!
Kirk - I am not averse to travelling for the right one and the black one appears to be in Hertfordshire so not a million miles away, if you have got the number of the previous owner that would be great. The black one certainly looks very nice and dare I say a nicer colour than the green one!
