Whether a hybrid is worth it or not is a matter of personal preferences. The analysis appears incomplete to me too.
For example, according to this website:
http://www.hybridcars.com/tax-deductions-credits.html
A Camry gets $2,600 tax credit. So for a tax PAYER, more than half the difference is paid by the tax credit. And if you save $500 per year as all the assumptions in the analysis say, you are $100 to the good after five years.
I drive 30,000 a year. Sales people drive even more. I drive a BMW, but have wondered if I would like a hybrid. But a sales person who in the car much of the time might find a hybrid does not fit their needs.
You beat me to it while I was typing! Good one.
Great thanks for pissing away yet more of my money Uncle Sam.
