Hey, Australia! Want me to put you on the map? Well, my choice would be the FPV (Ford (of Australia) Performance Vehicles) GT. I consider most modern Australian cars (the ones that I know anyways) as being sharply-styled and modest cars... all until you floor the gas and hear the sweetest music one can hear- the roar of an Australian V6 or V8. The FPV GT makes very nice noise. I just wished I could start more races with the FPV GT. But it's been in my virtual garage collecting dust and glair.
I didn't really think this one through, but my answer would be the FPV GT. If I think of anything else, I'll report here ASAP with a new pick.
