You'll be able to get daewoo parts from any Holden dealership. I was working at Holden (I'm a mechanic) when GM bought out daewoo, that was in around 2002 I think so that one won't be assembled in aus but should still be a good little city runabout. They are cheap and easy to maintain and run, and with the timing belt, it doesn't matter what car you get timing belts should always be replaced by 150,000km as snapping them can destroy the motor. Doesn't sound like a bad deal to me but if you can get the full service history and just make sure it's been regularly serviced and has no niggling reports on repair history

Toyota are Japanese by the way
