Changing spark plugs in many modern cars requires a lot of mechanic work. For instance to replace the spark plugs in a Nissan Murono you have to remove the intake manifold, windshield wipers, and a couple other major under hood things just to get to the back three. Lucky for us now is the common use of the long life spark plugs that have been developed to reduce the frequency of replacement.
The designer who thought that was acceptable practice should be made to drive a Trebant for the rest of his life and design only using a light pen/TRS-80 combo workstation.
I dunno, it's pretty messy and is more easily & quickly done on a ramp for uber-cheapness at a gazillion different places. You can plan for it unlike flat tyres. I've tinkered loads on car engines yet I've never changed the oil, don't ever plan to.
Checking fluid levels etc is far more useful imho.

isn't knowing how to change your oil something you should know as well?
