Less routine maintenance. OK. But the routine maintenance they do need is twice as expensive as gasoline motors. So maybe the same total cost between gas and diesel. And when it comes to actual repairs, you pay twice or triple the cost for a diesel repair than a gas repair. Diesel needs repairs too. Just like gas.

Last longer. OK. But you pay an extra $5000 up front. So you pay for this extra lifespan. Its not free.

Not sure but maybe overall the total cost between diesel and gas is about the same. Higher up front cost, higher repair cost, higher maintenance cost per event, is made up for longer lifespan, less maintenance, and maybe, maybe less overall repair. Ain't nothing free. If you need the benefits of diesel, extra power and extra fuel efficiency, its worth it. But if you really don't need that, then probably best to stay away.
