o yeah forgotten to mention about prices. Just for comparison, a basic BMW 320i cost $50000 AUD here, all you get is 4 wheels, some seats and a shell.
Holden SS = $45000 AUD
Holden SS-V = $52000 AUD (the v has 19 inch wheels, leather interior, satnav)

All HSV has the same 307kw 6.0L V8 engine but with different equipment and trim levels

HSV Clubsport R8 = $62000 AUD
HSV GTS = $74000 AUD
HSV Senator = $76000 AUD

The Ford Falcon GT cost between $62000 to mid $70000 AUD while the Typhoon starts at $59000 AUD.

Personally the Typhoon is my favouriate. It accelerates just as quickly as the V8 cars. 0-100km/h in mid 5 secs, better overtaking ability, and it handles better because the engine is lighter.
