The only concern I had before buying my Hybrid was the horsepower. But needless to say I have no complaints, I am able to get on the freeway & keep up with traffic with no problem. Since I've only had my Civic for a few weeks & have only filled up once my mileage was 38.6 mpg. I think once I break the car in that will go up. I constantly catch other drivers staring at the car, perhaps with jealousy!!
(Lack of) Gas consumption
The only thing I would change would be to add cupholders in the back seat & having the arm rest lock into place.
