It's great to see you've finally joined up Geoff and welcome! BM-Bob is lurking here somewhere as well.
We both know what a blast it is to drive an old Aussie Muscle car; however driving a 911 at pace through a long set of corners is quite simply something else again.
The cornering ability, the torsional rigidity and "feel", the sense of purpose and the sound of a howling flat six all combine to deliver a massive case of sensory overload. In comparison, the poor old Aussie Muscle Car is just not in the same league.
I'm sure you'll enjoy P-car ownership as much as I have. If you want my advice, do it NOW!
Oh, and by the way... don't waste your time on those 3.2 litre girly-cars

. Get a real 911, get a mighty SC!!
