I have no desire to buy a hybrid but this is some pretty tortured logic. A Hummer is expensive to buy, expensive to operate, and, a fact that I don't see in here, has the highest rate of repairs per 100 vehicles of ANY make sold in the U.S. It's hard to imagine one going 300,000 miles without a whole lot of repair shop time.
Just adding that a Prius is fun to drive. It's got a lot of zip, and it's quiet.
I don't think anyone should buy a hybrid to save money. If you like the car, you buy it.
We have a Prius. My husband loved it after he test drove it. It handled a lot better than the other cars he drove, and it was quieter. Being a computer geek, he also like the screen and other technologies in the car. Of course, right now he loves that he isn't going to the gas station often.
