F430 spider vs R8 GT
Hmmmm, whilst I love the F430 I think I will go with the R8.
Nissan GTR Spec R vs Dodge Viper ACR vs Porsche 911 GT3 RS
Well not the Viper, I can't imagine how hard and scary it would be trying to navigate through the country lanes round here with that thing, also too uncivilised and too un-refined. So it's between the GT-R and 911, I think it will have to be the GT-R.
I love the looks, it's insanely fast, easy to live with etc etc.
