I've just had my 100HP serviced by fiat in Wakefield and they don't even change the air filter or plugs!!i rang them up after the service to ask and the response I got was "oh, they get replaced next time". So I took the air box off to look at the filter and it was ready for a replacement! I was in two minds to do it my self , wish I had now as it cost £150 for basically an oil and filter change! The only reason I had it done there is to keep up with the full main dealer service! But you don't get any thing extra when you come to sell it really! £100 if your lucky!
