Nelson factors in other elements such as the mandatory $600 per year service plan to come up with a much more realistic cost.

Chesterton's Definition of Progressives and Conservatives

"The whole modern world has divided itself into Conservatives and Progressives. The business of Progressives is to go on making mistakes. The business of the Conservatives is to prevent the mistakes from being corrected."

– from Illustrated London News, 1924-04-19, per Wikipedia

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.
