Hey, looking to buy a used Audi, probably something like an A3 or A4 wagon, preferably AWD but not mandatory, maybe the Avant I don't know. New to Audi and wondering if there are years to avoid or a year and model that was really good and what type of things one should look out for. Probably would be looking at a 60k-120k vehicle, how do Audis fare high mileage? What type of work should I expect to have done.
