Just my personal opinion but I found the Vouge shit to drive, on the backroads of Wales in auto mode it couldnt pull the skin off a rice pudding, had to switch over to semi-auto to get it to go anywhere.
The XC90 and ML are much better to drive.....as I said, just my opinion
Not driven the 4x4 Audi, but the A8 pisses the RR hands down.
