Our Civic started out averaging 34 mpg. It increased to a max of 43.4. Now it is down to about 35. We mostly drive in a semi-city situation, and we are not quick start and stop people, we drive conservatively. I am not excited about the 40-45 mpg claims at this point since we have yet to see that on a regular basis. Otherwise, we really like the little car.
Easy to park; roomier inside than we expected. We have always been truck people, so we have had some difficulties in just getting used to a compact car of any kind but we are satisfied with this one so far.
I would like the nav system to have a back-track feature. If it does, I have not found it.
