Adrian feel free to drop by my place over the weekend and have a gander at my old mans 03 XR6T. He loves to talk about it and I myself can give you some valuable info regarding servicing, maintenance and clever mod strategy.
Standard brake rotors have been known to warp as young as 20000km's old, the power windows give up after a while, there were re-calls for a water pump issue in some cars (an o-ring) and also standard issue tyres were also replaced free of charge when there was a deterioration issue discovered.
Be aware of transmission related stuff (the early auto's are crap basically) and I do know a bloke that had his diff replaced for no reason. Dodgy trans service.
Among all things, Ford simply cannot be trusted to tint windows.. At all.
Personally I would steer clear of an 01 BA, AU falcons are marginally cheaper pretty much the same car/level of shitness.
