Thanks again to everyone especially Northern Lad...Ta for all the info.
I didnt buy it in the end. If it had been you (NL) selling it, I would of snapped your hand off but between yourself and the current guy(who seemed very nice and genuine incidently) anything could have happened to it, it certainly had picked up some minorish yet annoying body damage and had nearly 30k put on the clock. so all in all especially at the price I decided against and have picked up a 159 SW which I am getting at the weekend. Not the 2.4 sadly but hey next time.
If the guy got 4.5 grand for it he's done pretty well, overpriced for sure but difficult to come by so may be thats a factor.
Incidently if anyone is looking(or has a friend looking) for a 2.4 10v SW on a 51 in really superb nick with 86k on the clock and fsh then message me. The car has been really cared for by me and the 1 other previous owner and drives fantastic. I was in Milan in it last year and it did the 1700 miles without fault. I really would like her to go to a Alfaowner.com member who will look after her the way I have.
Take care all and drive safe.
