Well Japo cars are always a threat to Australian Market, hell even Korean Cars,
Buy Australian aka Ford and Holdens, well not sure about Holdens cause some parts are designed in Korea
Though this is from an R34 sedan using R33 parts, this sure does give you the tips and problems you may encounter, good luck

Though maybe not getting much attention as Skylines do, my black R8 sure does turn heads when i put my foot down.
Especially when going past chicks, hell even oldies as well, gotta love that unique 6.2L engine V8 rumble that Holdens can only produce
