I do work on the car myself except for warranty work. Here is one reason why:
I planned to replace the engine coolant. Went to Schaumburg, IL Honda dealer parts dept. Honda Service Manual directs you to open engine block drain plug to drain coolant as well as open the radiator drain. Manual states replace the aluminum washer on the engine block drain bolt.
Parts dept did not stock the washer! The Parts guy went to speak with the mechanics. He came back and said to me that the mechanics do not open the engine block drain when they do this work. So the Parts dept does not stock the washer.
Obvious conclusion: So even though the dealer charges customers the "book rate" for the work which includes the time to open and drain block, customers do not get that service, their cars are not serviced according to Honda proceedures. And this dealer claims that they are better than non-honda service people/shops.
