The reality is that we can't do all the repairs that are needed by the customers because of workforce development issues, because of the number of mechanics we have, so we maintain that it is in our best interest to make sure that third party repair shops have the parts and have access to the tools and diagnostic equipment they need.
In your situation of a large customer, absolutely a dealer will quickly realize that it's in his best interest to make that stuff available—the special tools, the diagnostic equipment and the parts—so that a large customer can do their own repairs.
