Definitely a great (and often overlooked) car. I still miss aspects of mine after moving to a GTI (the engine sound, comfort and reliability).
The Aurion didn't have many of the 'major' issues that come with the (more expensive) Falcons/Commodores like timing chains, diff bushings, transmission milkshake etc. I used to think the water pump going at 150000km was poor, but a looot (probably more than not) of Golf owners see theirs leaking at 40000km's. I can smell coolant from mine everytime I get out of the car and apparently that's normal 😆.
