All NZ based, are a heap more though.
I drive a 1990 Nissan Skyline GTS-4 (currently with a bung gearbox).
The car scene is pretty good, heaps of modifed Japanese cars floating around. I think we have the highest number of Ferrari's per capita in the world, second highest amount of Nissan Skylines after Japan etc.
