As long as you can get a cheap electric car, everyone will be selling them by then and once you switch you'll never go back, no oil changes, no exterior components that break down, virtually maintenance free.
Oil changes are probably the cheapest maintenance requirement for ICE. As EVs evolve I foresee a an increase in maintenance frequency in fluid changes (specialty fluids) including brake and cooling specific to the vehicle involved. No machine is maintenance free. Sadly, the manufactures will adapt.
Dealers here call it service one and up, they charge quite a bit in Canada. My Niro EV only needs tire rotation and brakes are at 200k because their regen, I have never had a ICE vehicle go to 200k yet. There are so many other benefits, instant tork, no smell, clean electricity is cheap as well.
