I think you misunderstood my comments.
I am aware that the two services are seperate, in my case as I had some warrenty work on the body fibreglass left from the previous year to be completed it was as well to have both done at the same time with the selling dealer, it involved a 200 mile round trip!
The job ended back at the factory (Autotrail) as they refused to accept the quotation from the dealer, the even collected from my home rather than pay the dealers prices! But thats another story.i
If there is work under the warrenty at the selling dealers expense/liabilaty, another dealer or garage would not usually be interested as the costs could not be recouped.
If you ask for a low milage service in the second year the cost quoted to me recently by a main Fiat dealer was £169. At year 3 dont forget its time to change brake fluid and additional items so it would add to the cost. In saying this I would agree that the costs at main dealers are expensive, but be wary, if like me you have an extended warrenty (5 years) read the small print. This sometimes does not take into account the recent changes in the EEC law! They catch you all ways.
