Since I don't have an Audi yet, in my case the question would be, "Why do you want an Audi?" I want a 4000 because I understand it's durable, crashworthy, FWD or AWD, fun to drive, ca. 400 lb lighter than my current Peugeot 504, and not too expensive to run as Audis go. I see it as the spiritual descendent of the Saab 96, of which I had 3 over the years.
