The old argument. Interesting, though, that modern car engines are much
more reliable than older (simpler) ones.

If all other things are held constant, then simpler is usually more
reliable. Modern car engines have the benefit of much better
manufacturing techniques, better understanding of fatigue,
better oil, etc etc etc.
