If you were in the north of Sydney I would recommend Scott of The Rev Doctor in the back of Hornsby (it's probably closer to Asquith).
There are dealers who will come to you to do the standard services, and who only charge standard service prices. Instead of arranging that, I get up 1.5hrs early so I can drop the better-half off at work, drive up to Hornsby, drop the car off, walk up the hill to Asquith station & catch the train to work. Then the trip home is an extra 2 hours.
I've rather (a) support his business than a "faceless" dealer workshop and (b) have him work on the car. He just ... knows stuff, picks stuff up. My Volvo project car (
waves to SuckSqueezeBangBlow) has a Supra gearbox, and there's a locating pin on the Toyota bellhousing which is almost not needed ... my bellhousing is Dellow not Toyota, I knew nothing of this pin & had been driving the car around (not properly sorted) for years. I asked if he could suss-out some vibration, he not only had a VS-or-thereabouts tailshaft fitted & balanced because the original was wobbly, he also added the locating pin where it was missing (there was even a hole in the Dellow bellhousing where it should have gone) ... now this is the sort of stuff people with knowledge are ever going to pick up, and it's not like he's a Toyota fiend or anything like that (his cars are pretty varied - although invariably old, I think he was almost disappointed that we replaced the VS with a new VF
).
And on top of that, he's using the same stuff that Holden dealer workshops use, and the "capped price servicing" turns out not to be much a Thing because he costs no more.
Only downside, as mentioned above, is no free software upgrades. But it seems they're not happening anyway, seem to be plenty of people around with 2013 VF's that've been dealer-serviced their whole lives & who still don't have the lines on their colour-touchscreen MyLink.
