I drove to singleton via the putty last week. Windsor bridge to Bulga Bridge including two toilet stops 150km 1hr 28mins.
Return Leg 1 toilet stop, lots more traffic, 2 trucks , 1 bus crawling up Colo hill and one random Breath test.
Casualties 1 kangaroo (died instantly) , front guard headlight bumper bar
1hr 30
Vehicle 1987 Corrolla twin cam
Believe it or not one of my favorite cars for these types of roads. I paid $450 for this car 10 years ago. In that time it has cost me two head gaskets and brake pads. Thats it
It falls over a bit on the hills or under 4000rpm but its a missile around the windy stuff.
