I drove around the southern highlands today via Warragamba, Picton, Hume, Mittagong/Bowral to the Treetops walk/Illawarra fly thingy, and back, didn't see any Golf R's either.
Did 400km of driving, that is over a third of the kms the car has travelled in its lifetime :) Near the end of the drive, even with some quite spirited overtaking maneuvers, I have seen the best economy so far, 8.5l/100km...normally about 13.5 for me :). Only half a tank used in 400km of driving!
