I have found that dealer service pricing can be variable. Sometimes good, sometimes bad. At least this is my experience with Honda and Toyota dealers.
My cars are older now. Just took the Honda in for an oil change. They had a special. But the real reason is that both Honda and Toyota give me a list of all the things that need attention (according to them) and the cost. Which is exactly why they often run a special. Other than the standard fluids, brake, transmission, etc, I take the list to my mechanic and he does what needs to be done. We will put the Solara on the road next month. First oil change will be with the dealer for that very reason. Other than that it goes to Elmo.
Overall, I believe that we have saved a fair bit of money by avoiding dealer service on most items. I do not have to pay for a fancy lobby, coffee service, rides to and from the dealer.
I believe that one reason our repair costs are low is because I keep track of all the fluids and replace them at intervals as per the manual. So...the cost that the Honda dealer gave me to do brake and power steering fluid flushes/replacement is in the ballpark of what my mechanic would charge. For just about any other mtce item I go to our regular mechanic shop.
