As for the model 3 and working on it... keep in mind that electric drivetrains require much less maintenance. You will need to do some of the normal brake maintenance (pretty much limited to fluid check/replacement since regen results is much less wear on the pads), tire rotations, and washer fluid top off, some HVAC checks/filter/desiccant replacements. The Model 3 has lifetime battery coolant - so that doesn’t need to be changed. As they get older, normal suspension and steering maintenance would be needed too.
Here’s a link to the manual with the maintenance schedule:
