My Fairmont station wagon is about to roll over 400,000 miles...it's like my SOHC4!
My SOHC4 looks a lot better, though.
The largest "problem" we have today in the industry is: electronics. The marketer who is trying to sell his product wants razzle-dazzle so he/she thinks it will sell better, so it gets lights. And sounds. And actuators of some sort that are neither needed, nor wanted, by the person who needs the 'function' provided by the 'product'. Cars/bikes/appliances/whatever, it has all become the same thing. (Do you really want an ultraviolet LED to set your glue? And when it quits, the glue won't set?)
If you have to use a voltmeter to diagnose it, or a computer to figure out what is wrong, chances are you will not take it coast-to-coast anytime soon. That's one good way to immobilize a population, which lends itself to conspiracy theorists...
I work in industry, making machines that make things that grow very large, very quickly (and usually make lots of noise doing it). Reliability is 100% of every single part we make for these machines. I'm happy to say, I learned how to do it from Ford (of old) and Honda (also of old), and SONY, long ago.
