on the road or anywhere else, the BF xr6 turbo will be better than the VZ or VY GTS or even clubsport R8... holden produce massive engines and big power, but their useless and overpriced...
The BF GT and GT-P are a great car but lack bottem end power (i have personally driven many gt's, typhoon's and xr6 turbos aswell as xr8s)
all cars are excellent with the 6speed auto gearbox
moral of my story... the ford is the better car than the hsv.. copy or not copy whatever ford produces is a better product even though i wont own one.
