After driving around in my hybrid for two years now. I feel as if I would be getting the same gas mileage if I were in a non-hybrid civic and I could of also saved $$$ at the time of purchase. Now come to think of it, if I were to get more out of this I would simply switch to an alternative fuel such as natural gas or corn oil instead. IMO, my HCHII could be just as fuel-efficient as an EX model except when sitting at the light. Overall, I'm still happy with my purchase and still planning to keep it for a long time coming.
