I think thats a very difficult question to answer. If I go to a dealer and have a good experience then thats service I expect, for me thats not a good dealer. If I find a problem, and they have a good attitude, nothing is too much trouble, get it fixed for me with as little hassle as possible thats what makes a good dealer. So for me, I'd need to wait till I had a 'problem' before I could recommend anyone.
