Mate. Im in Perth. If you need a Cosworth fix there are a few of us here that can take you for a drive! Im sure my cossie isn't as quick as yours, but atleast its still a Sapphire cosworth!
You would be better of buying a Evo lancer out here. Much better value for a performance car than XR5's. Unless you just want huge power with boat like handling, then go for a XR6 turbo/F6 or a HSV if your real desperate.
Just dont look at how much a Cossie costs to buy here!
