other than the fact that you sound like a muppet, i think you need to learn how to do skids better. commodores are the in thing where i live and i've seen plenty of them able to fry second gear.
also you would know that commodore gearing is much taller than skyline gearing, hence why it is slightly harder to do skids in higher gears.
and the nissan winning at bathurst thing is pretty pointless as anyone with half a brain knows that you can't directly compare a full blown group A car to a road car
but back on topic, the easiest thing to say to a commodore driver is "have you ever driven one? and when they say no, reply with "well until you have actually driven one, you aren't exactly in a position to say whether they are good or not. racing against one doesn't mean a thing because that person may not have been able to drive for shit"
