~~The car dealer said it costs $75 and 45 minutes to charge the electric cars!
Not even close. Maybe $5.~~
Maybe where you live, here we have no charging stations so that is the cost here from his business.
I don't want to start an argument so I'll just say this and butt out.
Keep in mind he's a car salesman selling internal combustion motors.
He's either lying or misinformed. There is nowhere in the country that electricity costs anywhere near that much.
Sorry
