I just purchased this vehicle yesterday. So far I think it is great. It has unbelievable accelleration, a smooth ride, sharp looking exterior, and very comfortable interior. I am not sure about the EPA numbers for fuel economy, but I am sure that may have to do with aggressive driving. I recently drove a family member's BMW 5 series sedan, and I must say the Accord Hybrid feels very similar performance wise at far less of a cost.
Acceleration, handling, sunroof added to 06 model...Fun to drive!
Bluetooth added to Navigation system for cell phone access, passenger side power seats, more interior color options (i.e. black leather with silver exterior unavailable...only grey is available). Possibly make a sport edition w/ added stock customizations as in Civic SI.
