Graham,
To look at an Audi is not considering the dark side - a Falcommodore is! Bear in mind a Passat is an A4 with a different body - the same applies to the A3 and the Golf. So the vehicle size is your first decision.
I have driven various Audis for almost 15 years. They are well-built, reliable vehicles. Yes, they can cost more to maintain but if you are buying a decent european car, they all cost more than a '67 beetle to run.
I would suggest that you try

Please note that, like all vehicles, not all Audi drivers look after their vehicles - then repair bills can skyrocket. It is better to find a good car than to buy cheap and pay for the repairs.
There are a number of Audi owners in Adelaide who will point you in the right direction for most repairs.
Here is picture of mine.
regards and good luck
Rob
