Charging up an electric car is so much cheaper than for an fuel based car. Plus you might even get the electricty for free. If you own a Tesla you get free access to the free unlimited super chargers all around. Sure you have to pay that cost indirectly when buying the car but atleast you don't have to pay later down the road. And Oil could become much more expensive in the long run. Electricity cost are not expected to rise so much.
I drove once in a Tesla as a passenger and the cars are just grat, super quiet, so stylish and the big screen in the middle is awesome. If I had the money I would go for a new Tesla.
