Yes, the measure the same thing over and over and over everyday of the year, year after year. I also doubt your 'hearsay' cost for the equipment.
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.
