Wait, now you are comparing a luxury car to a Toyota truck. That doesn't make any sense at all, so your question "Which one makes more economic sense?" doesn't make sense.

By your logic, everyone who buys a BMW M3 or a Porsche Boxster ... or whatever ... is dumb because they should have bought a Toyota truck because it is only $19,000 over 5 years.

If I compared it to a Leaf, it still wouldn't make sense. A Leaf is $35,000 MSRP. The Leaf is built on the same platform as a Nissan Cube ($14,000) and the Nissan Micra ($17,000). I could run the same comparison between the Leaf and the Cube and come up with the same results.

Except, if I did that, it might even be worse. See, I picked the Tesla Model S for a few reasons. One being that it's the subject of the debate here on HN, and second is because the Leaf gets 100 miles in range. The Model S gets 250. The Model S is also capable of being mostly recharged in 30 minutes (for free), and while the Leaf can also be recharged in 30 minutes at one of Nissan's charging points, they are not free. You would end up paying a fuel cost for a Leaf, no matter how marginal.

I was using a Toyota truck as an example, but also noted that the rented minivan in the example cost just as much in gas. Minivans secondhand are also generally cheaper than trucks in my experience. The difference between a Model S and a Porsche is simple in my opinion: if you don't like the Porsche, the BMW is a comparable option. The Ferrari is nice at that price point as well. But you can't swap out the Model S with a comparable option. Like I noted in the first and second paragraph, the cheap competition isn't much cheaper at all, and in all honesty is a much worse value for the money.

If you're buying an electric car, it doesn't make sense to not go with the Model S. And if you can't swing the extra $30,000 for the Model S, just realize that the Leaf is ($35,000 + $100/yr in electricity + $1400/yr to rent a car) $42,500 for 5 years compared to $66,000 for the base Model S compared to $19,000 for the gas-guzzling 4x4. The cheap mainstream competition still doesn't beat a 5,000lb, 14 year old truck with a V6 engine. How many years would it take to break even on that investment? Trading in your old car for a new electric car isn't going to save you money. It just isn't. Especially if you're renting another car as well.

Okay, but ... did anyone ever say that it would save you money? I don't see that in the thread anywhere.

I certainly wouldn't make that argument for cars of today. But I see how rapidly the price is coming down, and I see what price targets Tesla is aiming for, and that is pretty interesting.

(And if you really want to compare price, it's probably a good idea to try to account for externalities. It's hard to estimate those for gas cars because so much is kept secret, but they are substantial.)

Actually, I own a Leaf and it does save me money against buying a comparable compact car like a new Sentra. His math fails to account for the full range of costs associated with a gas-powered vehicle including oil changes and engine maintenance. Also, I drive considerably more than my 17 mile one way commute, so it makes a lot of sense for me.

Here's a great spreadsheet to get the real costs: http://www1.extension.umn.edu/environment/energy/vehicle/
