Really?  My wife just traded in her A6 and it was one of the best cars we’ve owned.  We feel like it had a lot to offer for the money, especially compared to MBZ and BMW.  Basically, we were able to get all the safety features, size and power comparable to the BMW 535 or MBZ E320 for the price of the BMW 330 or MBZ C320.  The A4 might not compare as favorably, but the A6 certainly did.  And it was a very reliable vehicle, only in the shop for three unscheduled visits to resolve minor problems.  As for the interior, I know it’s a lot of personal preference, but I like Audi’s better than BMW’s or the newer MBZ models (I like the older MBZ interiors better – i.e. with the window switches in the center console where they belong).

As for the Q7, I am guessing it’s based on the Touareg/Cayenne platform.  It will likely be a decent vehicle once the typical European new model bugs are worked out.  The lines from the side remind me of the R-class, but with a more SUV-like styling as opposed to the R’s minivan looks.
