You can still find that in heavy equipment. My Kubota tractor is pretty easy to service and designed for 8-10k hours over a 30+ year lifespan.
The thing is designing for that costs a fair bit, just take a look at the step from riding lawn mower (~$2k) to garden tractor(~$15k) for similar horsepower. It's not a direct apples to apples comparison but does go to show how much more something overbuilt can run.
