I understand that to completely understand the complete make up we must examine all the criteria that you listed above, however I am simply interested in the support staff to technician ratio. I should of been more clear about my expectations from my question. I am trying to understand if there might be an industry standard, I have visited several automotive dealers, they seem to run 3 to 4 technicians to 1 support member in my experiences. Our industry doesn't seem to be willing to allow such a saturated support staff?
