Points about wages are true, but I think another important factor is that the general trend in ownership has moved to one of expected change (contract-lease cars in particular) so there is a general assumption that people will just "get a new one in a year or so" and they won't be fussed (or they will claim on insurance). Also people will generally assume (maybe subconsciously) that other people live by their values, so (well-paid or otherwise) garage mechanics may not even see the damage as a problem if they have a throwaway car or something on a contract that will be replaced in a relatively short space of time. The idea of somebody keeping an item like a car for years and years is now quite alien, even compared to only 10 years ago, so many of the people working on them now will not have grown up with the mind set of preservation, and will have been trained in an environment of the disposable part rather than that of understanding and fixing the problem or (even better) preventing the problem in the first place. This is obviously where the holy grail is a garage run by a trained person with experience and a passion for your make of car- vocation for the job and understanding of their subjects will naturally ensure they do the right thing. Maybe we should set up a forum5 garage service!
