Routine servicing I do myself, and I'm fortunate that my Astra 2.2 and my wife's Barina both have chain-driven camshafts. The stuff I don't do are things like automatic transmission fluid changes, wheel alignments and so on.

Our two local Holden dealers in Canberra are terrible. My wife's car has been to each one once, and I would never take either car to either dealer ever again. I don't worry so much about the price dealers charge, but the problem is the servicing never gets done the way it should be (important items overlooked, engine overfilled with oil etc etc).

Before the Astra I had a Hyundai, and the dealers for it were much better.
