I have a Q7, just did home to Morzine with 4 bikes on the tow bar.
It was extremely quiet, very easy and it performed flawlessly. Had it for about 6months. Before that I had a 5 series estate. The Q7 is about same length, is wider and does fit in spaces less (easily? or just less…)
It is a ridiculous car, it is a crazy size. But it works and fits what I need it for. It does not get used around town. Fuel consumption – have seen it show an average of 40+mpg for a journey, but that is very much the exception. Did average something like 34mpg with bikes through france @ 82mph. Long term is currently 31mpg (I am not very patient).
Haven’t used the 7 seats much. But would not consider buying the Q5 (that seems too compromised in my mind).
Was ironic in the winter – take a 4wd to work in the snow (on pirelli Pzero) or 2wd with winter tyres. I did both and the 2wd was almost certainly safer.
Apparently you can’t get anybody who wants the 4.2tdi (a friend of a friend was looking to get do a trade-in and nobody would bid for the car).
