They save you gas and some maintenance, but that’s about it
I'll cop to that. My sole motivation for going EV was to minimize the potential maintenance burden in the long term. In my experience, the internal combustion engine was the single largest maintenance cost, for both money and time, that wasn't a wear part (e.g. wipers, tires). The sheer number of moving parts and subsystems in an ICE vs an EV is staggering. I'm taking a bet here, but there's just less to break down on an EV and until that's the standard, it's a convenience I'm willing to pay for.
