to be honest jason,
usually the better way to go say if you wanna go check out a car in nsw or something.. is call up a mechanic over there and go 'hey can you guys check this car out for me' etc etc etc... they check it out, give you feedback on all mechanical things, you go 'BAM!!!' deposit... fly over there, take it for a drive yourself if you prefer, and then buy...
but if this dude was flying over... he wouldve had a mechanic look at it and made a deposit at that point... it's the smartest way to go or the car is pretty much still free game '-_-
