there is a major flaw in his argument, a diagnosis on a car can take anywhere from 5 minutes to days on a really bad problem, the 39 dollar exam he is talking about is a couple of x-rays and a quick look at them. The amount of time spent is roughly the same for each one and I am sure he more than makes up the cost when the does whatever work is needed. Plus he is not taking into account the other expensive tools and equipment a auto shop and it's techs needs to do their jobs.
A very ill informed elitist opinion, LOL the health and well being of mankind... Really? wow only a little full of himself. Your not a open heart surgeon buddy your a dentist.
