Modern diesel regular maintenance really isn't bad until you need to start replacing injectors - which seems to happen far too soon IMO, perhaps inadequate OEM fuel filtration.
Thousands of dollars to rebuild or replace injectors at under 200k miles seems ridiculous to me. Always had good luck with my diesels but not sure I'll own another unless I'm towing long and hard.
filtration + EPA regulations + degregaded fuels = bad combo
