Welcome aboard Jon. Looks like we Fiat fanatics are taking over the forum
Theres plenty of Fiat info throughout the forum, take your time and go through the threads, and give us your valued inputs. It would be a very refreshing point of view from you, as most people here still associate the 1100 with Bombays taxis. (There are still 53,000 plying the roads as taxis there!)
Rest assured you can find pretty much everything in terms of spares for your car here, and we'll be glad to help you out. Infact theres another gent from NZ lurking the forum as well, with a racer based on the 1100.
Cheers
Karl
