The Tesla Model S is a fine car and it has much to recommend it. However, +Elon Musk should not be resorting to these kinds of shenanigans to sell cars. To claim that the time you spend filling your car with gas is worth $100/month is a bad joke. What about the time you have to spend looking for a charge station if you're getting low on electrons. 

Then there is the $227 you subtract if you are using the car for business. If you are using any other car for business, you could make the same claim so this one is a wash and if it's just a personal car, you can forget it anyway. 

You're going to pay $1,100/month to finance a  Model S and that's that.
