Rust would have appeared by now. Look close (rear fenders and hatch). It may even have been repaired on the one you're looking at.
My '05 is at 72,000kms now. Had it since new and the only real complaints I have are doors freezing up way too easily and rear brakes needing replacment way too early (48,000kms).
It's been a good little hauler...so far. It's still only at 72,000kms, right?
