At times I wistfully miss a points, condenser , carbs etc, then I realize I have driven >100K miles and the only maintenance other than oil changes ~ twice a year and valve adjustment checks at same time
...I have tested several ignition trigger setups, all worked. That was voluntary so I cant count that.
Replaced: 4 spark plugs.
...I have reworked the shocks twice, installed a custom AC rig, replaced the entire rear suspension, and put an automatic in it in that period, but only changed the plugs once.
I did have to replace the air filter as the first and last time I tried to clean it the cleaner caused the uni filter to dissolve.
It is burning some oil now, the used 1.8L jugs/rings must be nearing end of life.
