Had only a brief read.
What I hate is the way they try to justify dealers' expenses. I don't care what they charge. When you can get a part or a service from an independent specialist for less than half the price of the main dealer, you hear people exclaiming "That's highway robbery!" or "That's extortionate!". That is equivocal to stealing.
Are you gonna sue people/customers/potential customers for slander?
This is like the entire crap with people naming and shaming dealers, then those dealers suing for libel.
