Have you tried the fiat dealer in sheffield that isn't stoneacre? The one on the Pennsitone road towards Hillsborough? I found stoneacre were very keen to sell me a car they already had in group stock but didn't seem to want to order me a new build... I went in on several occasions to try and order and pay a deposit but was fobbed off and told someone would ring me next week or to come back next week when the person with the passwords is here. I ended up using a dealer 60 miles away who I dealt with over the phone!
