If nothing goes wrong, the first two-three years are practically free for an EV. Home charging costs pennies and if you're really stingy you can use free public chargers.
Then you might need a new set of tires maybe a quick maintenance at the dealership and you're good for a few years again.
Unless you also have solar panels at home and want to have the hassles of making sure your EV only charges on sunny days, you're going to be paying rates for electricity close to rates for dinosaur-fuel, especially if you're comparing to a modern 60 mpg gas car.

Still a hell of a lot cheaper than gas over here (coming up to 2€/litre in some places). Even diesel is over 1.8€/litre.
At 15kWh/100km consumption it'd cost me under 4€ to drive 100km on my EV. My old Prius did around 5l/100km, which would be closer to 10€/100km.
