Thanks for the replies. I've contacted two local Fiat Dealers who both told me something different about when I should get the car serviced. Thought I'd better contact Fiat UK and this is their reply:
"[FONT=Arial,Helvetica]Thank you for contacting Fiat Group Automobiles and for your interest in our products.
Regarding services on your vehicle, a full service should be carried out at either 18000 miles or after two years, whichever comes sooner.
For what regards having a service after one year, there are certain elements that need to be checked and/or replaced in order to maintain the warranty. This is called the low mileage annual service, and as per the service and warranty booklet, include oil and filter checks and replacements.
Your local authorised Fiat dealership can provide a more exhaustive list of checks carried out during the low mileage annual service."
[/FONT]The advice I've received seems to go against the car manual says so I'm still none the wiser, but looks like the car still needs an annual service.
