My situation is this: I currently own a 2011 Civic and I have been able to hypermile it to an average of 44.3 mpg over the last 10 fill ups. Now I have almost 53000 miles on it and the dealership has a 2011 CR-Z demonstrator so I'm debating trading up. Just looking over people on fuelly I'm not seeing any extraordinary numbers that make the switch worth while. I figured the best people to talk to would be on CleanMPG as we thrive on getting the most from every car. Thoughts ?? Exclude the fact it is a two seater as I'm more than willing to sacrifice that for the cause of better fuel economy.
