I have held off buying a hybrid simply because the technology versus the price doesn't make any sense yet. A good(Toyota)-mileage car was/is still more economical choice. Hybrids don't really do much better.
But it looks like the technology is improving and soon will actually make a difference. But the catcher is......"if owners keep them a few years".
I figure that a few years means more than 5.
