Bought this for my wife in June.
After about 4000 miles (1/2 of which was ATL to WI and back), it's been a great vehicle. Quiet, absolutely SOLID driving.
28mpg on the highway (3.0 TDI)
Wife is tickled pink, and is addicted to torque.
This replaced a Honda Odyssey that we bought when pregnant with our 2nd child.
"This will be the only minivan I ever own!!!" was her quote. Loved the vehicle, and got lots of great use out of it. Time to move on.
Back to the Audi. I realize that long term ownership is the central discussion here. Of course, prior to first service - we have no idea. I sincerely hope that this model has enough years under its' belt to have worked out all of the bugs. If lots of issues before out of warranty - we will reconsider the long term plan. Same powerplant as used in M-B, Porsche and VW - if I understand correctly. Cant imagine that it can be all that bad. Most concerned about electronics and goodies - but hope that if serious problems, will work themselves out within warranty period. She is pretty careful and gentle on vehicles, and I hope that bodes well.
Comments on the overall package: Seats, Dash and materials are all nice. Carpet - looks like it came out of a 90's VW. Don't know why they did that. We did put the all weather mats in - so I am optimistic that the carpets will stay clean.
We have not had integrated nav before - and so far, she likes that a lot. I think not quite as advanced as some of the other makes - but we also test drove a new Acura MDX. My wife actually cried because it was so hard to use. Two screens and lots of buttons besides. That killed the MDX immediately.
The Q7 has great legroom in back (middle row), and 3rd row is kids only - but that was a big deal for us, as our folks visit frequently. We need the occasional space.
Cargo - not anywhere close to what the Odyssey had, but we do not need that very often.
Space for all the little junk that you always bring along - the Q is a bit short in that department too.
Sorry for the scattered pseudo-review, but those are my thoughts. Happy with the vehicle so far - and if I didn't need a utility of my own (Outback) to slog through lousy ATL area traffic, I would love an A6 - or other variety of their current lineup.
