obviously, they dont do the repairs for free
but i cant imagine they get paid by the manufacturer at their standard parts and labor rates, otherwise so many dealers wouldnt be stingy on getting warranty issues acknowledged
so does the manufacturer pay them at some negotiated rate that varies from dealership to dealership? or is it at some calculated break-even point to the dealership? or do they pay them normal rates, but with some auditing process so that the dealerships can't rip off the manufacturers (like they do to their customers) ??
