A social problem ??
It's fundamental, surely - if you pay for something, then that is what you must receive.
If you mean, 'oh, well, they are all like that' then there may be an element of truth in it, in the sense thare is a culture of main stealers - sorry, dealers - ripping the customer off, and it has been prevalent for years, with all makes. I have had bad experiences with Ford, Volvo, and VW in the past. I have even resorted to marking parts with a dab of paint prior to my car going in for service, only to find it hasn't been touched - a que for me to visit the service manager and loudly bang on the desk!
Thankfully they are not all like that. I am currently a customer of Hodgson Mazda in Gateshead, and can't recommend them enough, they have been faultless, even though they didn't sell me the car in the first place.
