As if that's the only problem with his numbers. He is comparing a large luxury sedan to an entry level, small car.
I know two people who own Teslas, and neither of them got it to save money. Teslas are quite comfortable, halfway good looking, and offer good performance. They are also a statement that goes beyond 'I can afford this.'
I have a heavily modded 460hp S60-R Volvo, and a very clean 26 year old Toyota Supra. A Tesla pretty much covers all the strengths of my two cars: performance, turning heads, comfort on long trips, maturity... in one car.
If I wanted a Tesla, I'd buy one. Saving money on gas would not be amongst my reasons... but unless something drastic happens to my cars, I'm happy with what I have. I cannot imagine what would make me buy a new Civic. Losing my job, having my savings wiped out and becoming unemployable wouldn't. I'd buy an old car I could fix and maintain myself.
