I've been the beneficiary of "goodwill warranty" and I have a great service department to work with. That has not always been the case.
In my view, "stealership" is a term only to be applied to those firms that DESERVE it.
As Randy said above, not all dealers are out to empty your pockets.
Many consumers don't know enough about their cars, or how the business is run, to understand how a repair or service to resolve a driveability problem is processed. Further, there are those out there that believe that anything that goes wrong with their vehicle is a direct result of a previous service or how the vehicle was built.
That, in itself, is asinine. The manufacturer and their dealer network have NO CONTROL over how the owner uses (and at times, abuses) their vehicle.
Sure, there are some firms that qualify for the term "Stealership" and rightly so.
But it's wrong to assume the dealer you are working with is out to screw you. The majority of the folks working in the service and parts departments are regular folks, trying to do a good job and provide service to the customer.
The sales department, however, is another story...
