I tend to use an independent specialist although my local main dealer (Desira Norwich) has done some work on mine including a recall for minor rectification of a cable routing issue under the steering wheel which apparently had the possibility of causing complete light failure all of a sudden. They have always been very efficient. Might be worth checking if yours is subject to that recall or had it done before you got it. From various posts on here, it's obvious that standards vary enormously between dealerships and it's just lucky if one near you is any good or, indeed, whether you are lucky enough to have an independent specialist within striking distance. I have also read, I think, that Abarth/dealers have recently changed the recommended oil and service intervals (made them longer) but I am going to stick at 9k for oil and filter changes. Tyres and pads are, of course, 'as required' items and slightly odd that they only recommended one tyre changed - unless one had cuts in it or something, they usually tend to wear in pairs unless maybe yours were odd ones when you got it? Anyway, hope you sort things out with your dealer to your satisfaction. You can always show them your handbook that details what they should be doing or find the relevant section on the service details on this site and print it out. If you want advice about independents where you are just ask on here, saying whereabouts you are, and I am sure you will get replies.
