Yeah I use them - sort of pledged allegiance to them if they fixed my warranty problem I had at the time and standing by my word - until the service manager (if he's still there) fxcks up again.
The service manager is/was a fwit, but the foreman was a good guy and is there to help - rebuilt my engine and it's going strong - which kind of surprised me.
Haven't had any issues since, but if I didn't feel a bit of moral obligation I would drive the extra 10 ks and use Motorama Hillcrest - have heard nothing but good stories from them.
They have the QLD state service manager (Russell I believe) and perform all necessary hotfixes without being forced to do it (he also probably finds/has all the hotfixes/warranty issues first being the state manager).
Good luck
