I found Aussie car dealers pretty good when buying my two cars on moving here last year. Compared to UK at any rate.
A couple of bad ones but mostly all sensible people, and not too pushy.
The funniest was a proper old school guy who was very nice, but insisted we meet "the boss". We get dragged in to see a guy in his mid 30s, obviously very busy, that had the face of "why are you bringing these people to see me".
My most pleasant car buying experience was actually back in Blighty. A dealer was setup whereby they give you a price list, and a button you press if you want to actually drive something. Zero staff stalking the lot. Bliss.
It helped that it was after a terrible place where the guy tried to sell us a Chevrolet Aveo about 5 times...
