I think good bad or indifferent service is endemic to most brands. Here in dear old Adelaide the BMW dealership gives the best service, the Audi dealership is so-so and the MB dealership is woeful from all accounts.
Go to another city and it is all different. I worry when the head office of the brand gives bad service when you try to escallate issues beyond a particular dealer.
I have been extremely happy with Adelaide Motors so far, they have exceded all my expectations.
