36.5% is still a hefty savings and pays for the extra upfront cost after 5 years even at cheap USA fuel prices. Economically there is no reason to purchase conventional gas cars anymore.
I'd say your 12 years of life is quite pessimistic. I would expect a Ni-MH hybrid battery to last 15 to 20 years for most people.

Some are using 12-years as the statistical lifetime of a new car. I've no way to vet that.
