Definitely, the car costs more.
But speaking purely in terms of maintenance, costs are nearly 0.
Assuming I don't but a pot hole, the tires will last me 7-8 years at minimum (I drive a bit under 3000 miles a year).
Brakes are barely used with an EV.
Insurance + tabs is my largest cost.
I bought my EV cash a few years back when prices were super low thanks to hertz offloading their fleet.
