All - back to topic ;-) - I have news!!
I am now the very proud owner of a 100HP - well almost, deposit paid, collecting in 7-10 days.
See link in post #66.
Saw it at 9am today. Totally immaculate outside apart from one scratched alloy which I can sort out in time. Otherwise clearly a much loved car. One previous owner, clearly an enthusiast, right down to the red FIAT graphics on the wheels - not sure about them TBH.
Inside it is like new. You really can't tell it has been used at all!
I liked the dealer. It's an Alfa Romeo specialist and almost like a museum inside with classic Alfas and parts all over. Used to be a FIAT franchise and still sells them - check out their site - Black & White Garage - Cold Ash.

He agreed to MOT it, service it (both due), touch up the alloy scratch, and do four wheel alignment - was slightly out on the test drive.
It had been reduced from £5500 to £5200 this week. He wouldn't budge below £5100 (I tried!) but it was in such good nick (and the dealer knew it) that I decided I couldn't miss out!
Very happy and can't wait to get my hands on it!
Thanks to you all for all your help and advice!
Cheers, Dunc
