> Full EVs: Less moving parts = less maintenance required = less issues to worry about (think no oil changes, no timing belt changes, no spark plug replacements, no belt/filter changes, no exhaust system checks, etc).

The above is a tiny part of the costs of an ICE. Sure you have to do it, but either it isn't common, or it is cheap. ICEs have gotten very reliable over the decades.

Meanwhile most of the parts of a car a common between an ICE and EV. You have tires either way, which need to be rotated (do you?) Shocks/struts, rust, tie rods, AC compressors, just to pick a few random ones.
