I have to concur, have come accross many many landcruisers in the mineral exploration game that have lots of K's and going strong. One drilling contractor I do a lot of work with leant me a ute, and they noticed I was takeing it easy and double clutching (gearbox was a bit notchy and it had 600k on it)
They told me that if I treat it nice it'll start expecting to be treated nice all the time, they figure that if you drive them hard, all the time, they only ever need their 5000km services - I'm not sure I agree with them, but their vehicles do seem to survive!
