Well, my car dealer tests a wide spectrum of things on a number of different vehicles. Their equipment is expensive. And I’m not bothered by your judgment regarding my assessment of the cost of the equipment they use. And yes, dealerships do run tests on vehicles that were not manufactured by their parent company. I wonder how they do that without charging $27,000 a pop and taking weeks to do the work.
BTW, they will charge about $100 to tell you what your engine check light code means!
You claim the $27k is too much but won't provide a test plan to support a lower value ...
