Thanks IT
The Q7s I was looking at were all fitted with a TV tuner. So that is good to know they get twin pane.
I'm really leaning towards the RR on the basis that most reviews state the Q7 is a bit plastic and tacky... where as the RR is clad in leather and rides rather well.. there is also the fact that the Q7 is not as capable off road as the RR.
So I think I'm now shopping for RR
