Astra, Barina, Vectra, etc servicing

[MK]

Hi,

I recently took my Vectra to a Holden dealer to have a problem diagnosed and
rectified, but they said nothing was wrong and charged me $80 or so for the
pleasure of spending 4 hours in their waiting room.

There seem to be quite a few non dealer specialists for other makes (Volvo,
Audi, etc) - does anyone know of any non-dealer specialists in Brisbane for
these types of cars?

Holden are probably good at looking after the Commodore family, but some of
the cars they sell seem a bit beyond the capabilities of their service
centres.

Thanks in advance,

MK
