Don't rely on that as an accurate average life of a Hiace. Couriers have the engine running all day, it's stopping and starting that causes most damage on an engine. Airport shuttle vans are reaching a million k's since they're running the whole time for long distances. So if you're using it as a commuter and taking it to Manfeild and back, you won't be getting so many k's out of it
In saying that, Hiaces are damned reliable so long as you go for a petrol model. Toyota diesels can be dodgy apparently
Get The Dog and Lemon Guide. It's a good book if you want to know about the reliability of second hand vehicles in NZ
