Problem with the Allroad is that being an audi parts and repairs a VERY expensive (think pads and rotors every say 30k at a cost of around $2000 an end, timing belts are due every 3years or 60k (whichever comes first) around $1800 for the full service. They are a nice car and absolutely fly (my old service manager had one and i used to run around town in it) but Euros dont age well in Australia especially once they get to 100k they start falling apart. also as they get older electrical gremlins rear their ugly heads and thats when it gets real exxy.
A cheaper (Japanese) option to the allroad would probably be Subaru Outback H6, wagon, raised ride height like the allroad, Leather and all the luxuries, 6 cyl so u have decent power, reliability (look on carsales theres plenty with 200-300k on the clock) good resale as well. From $13k-20k for a 3rd gen shape and 20k-30k for a 4th gen
My recommendation would have to be the Toyota Aurion. ok it drives the wrong wheels, the park brake is in the wrong spot, but Value for money, reliability, space, economy is hard to beat. That will be my next move for a car in general.
