The problem is, those concerns still apply even if the owner is hiring the service done.
When I was working as a mechanic, we had a few customers with land rovers (most of our business was trucks & SUVs). The land rover owners had to pay roughly 2x for everything, simply because the cars are so much more time consuming to work on. And from family members who have owned them, BMW & Mercedes are just as bad, albeit slightly more reliable. If it is time consu3and a PITA, the customer will be charged more.
