My Tesla pals gloat over the fact that they spend nothing per year on oil changes, tuneups, or really anything except for tires and getting their cars washed. And windshield wipers.
There’s just not a lot that needs any maintenance and a fraction of the parts that an ICE auto has. Teslas “phone home” on a daily basis and Tesla will know if something is failing before you do. They will tell you that they want to come out to your house and fix something.
