We are looking at one of these quite seriously and was wondering if there had been any reliability issues. My wife will be driving this primarily with the kids etc and we don't want to worry about the mechanical or physical stability of the car. On the flip side we are also looking at a BMW 330XI. We like these two models mostly because the used price is quite resonable and the all wheel drive is a near must for our area. We are quite new to the Audi arena and appreciate any opinions or advise.
