All depends on the price of petrol. If gas is 4 bucks or more, the average 15k mile per year cost savings will be $2000 per year. At a 100k lifecycle for the car fuel savings will be $14000. 150k will bring a 20k savings. Plus add in the $7500 gift from Dear Leader and you have a car that makes economic sense.
Now I'm too pay 40K for a Corolla with a battery pack that costs about half of what the car goes for if it craps the bed.
No thanks.
