I think that the mechanic set's his or her own standards. The training they receive has a lot to do with how they work. It's like raising kids what goes in is what comes out. The large dealerships have large overhead so productivity is an ongoing issue. The dealer usually encourages quick effective procedures sometimes with little oversight, sounds like a government agency a little....... As we all know everyone is working there own pay plan so thats also an issue so we as mechanics being from a capitolistic society do tend to like the good investments over the bad ones. The problem with Inde's is quickly after they leave the dealership network their training becomes outdated as the science of automobiles is ever changing. I have owned my own inde as well as worked many years at a dealership and the quality everyone wants is in the individual mechanic, not the store. As for integrity my pop taught us it is something we are born with but once set aside it is nearly impossible to get back. You may have noticed I don't refer to myself as a Technician, thats a label. Mechanics repair cars.
