>> People run diesels due to durability. They run at lower RPM than similarly designed gas engines, and last longer between rebuilds.

Reliability is one of these stubborn diesel myths that refuses to die. The lifespan of modern gasonline engines -when driven normally- is several multiples of what the average owner will drive the car for before it is replaced. You can easily put 300K kilometers on a gasoline engine before it needs a 'rebuild' (which typically involves not much more than changing the piston rings and rod bearings). Around 150K you may need a mild cylinder head revision (valve seals, valve seats, tappets) if you torture the engine enough. You won't have to break the bank for either of those. I don't know a single person except myself (driving a 25 year old car with a high-performance engine) who ever needed an engine rebuild.

Meanwhile, regular servicing for diesel engines is guaranteed to be more expensive compared to a gasoline engine, so in the long run you will not save any money on maintenance unless you drive your car without any care for reliability.
