Save your money. My mate has a BA GT-P and it's not fast. It should be a rocketship for $85,000, but it's disappointing. It's just so bloody heavy, it's 1800+ kg.
An XR6T modded for about 400kW would be much better, and you'd have about $50,000 left over. But in the end, they're all just Falcons.
I will stick to my falcons and you stick to your volvos, i know what i would prefer LOL

I just like the GT, they have plenty of poke, i dont want a V8 Supercar.
