I disagree, dealers have the potential to report and show where dollars are wasted and drill down in to misuse/wheels/repairs etc.
We as a dealer add techs every year and get busier and busier.
Most in house service companies up here have realized the importance of having properly trained techs and have opted out of having there own in house maintenance and going back to the dealer.
This may not be the case in the U.S but it is here and although I don't agree with the way Bigdogs stated it I have to agree with him. Most in house techs you will find were factory or dealer techs that couldn't cut it and that's why they are on here bashing dealers.
