Electric cars will be the future this is clear, but at the moment they are expensive and in case you need to replace some parts for example the windshield is 5-10 times more expensive than for a classic car, at least in the case of Tesla model 3 changing the windshield costs over 1000 Euro.
But you are not going to pay for it right unless you don't have Insurance for your car. 
Look at the maintenance cost not the spare parts.
While you are at it, COUNT how many parts are used in a typical ICE vs en EV. It is baffling people are so blind to even notice this.
Take a look at the inside of the typical ICE, then look inside the EV, note the simplicity. This matters in the long run. The Tesla barely uses some oil for the driving wheel and the (much fewer) moving parts, while the others have gazillion pieces that degrade and need to be replaced periodically: separate types of oil, filters, hoses, sparks, water, fuses, etc, etc, etc.
An people dare to insinuate an EV is more pollutant, as if the EVs were leaking oil and fuel (and fumes) all over the place and not the other way around...
The windshield for the Tesla 3 might be more expensive, but that is because that particular car has long windshield like the modern Volkswagen. If you want cheaper parts, get a simpler car from another brand or just another model (eg. used S vs 3).
