Depends, I have been taking my truck in to the dealer for regular services because I just don't have time, and they can do it for the same price as I can buy the oil and filter

I do my own air/fuel filters, rotate tires . . . etc.

I have only had one non warrenty problem and it involved the dealer's body shop (only trustworthy body shop in this small town).

The ford dealer up here has a pretty good service department, but the parts department is a bit of a let down. There is also a couple of local shops that are really good and my truck will see them for any work that I can't do, after the warrenty is off.

Ok, my fingers are sore from typing now
