Most car dealers in our area (all make of cars) have realized they were loosing a lot of business to independent shops due to their pricing policies.
I don't mind paying $85.00/hour when I really need a specialist to work on my car. If I need a job done where expertize, knowledge, experience, expensive diagnostic/repair testing equipment is required, I'll pay the price.
An oil change, tire change/balance and routine work where a fresh-out-of-school junior mechanic with basic tools does the work does not warrant $85.00/hr.
Most dealers in our area have understood this and have set-up labor prices according to the complexity of the job to be done....and are gaining business back.
Driving a Mercedes is not a good enough reason to be the subject of highway robbery by dealers.
