I was extremely hesitant about purchasing a 4 cylinder, but after 2 weeks of ownership in hilly country, there has been no problem with power. It cruises comfortably, the seats are fabulous, and there is definitely enough power to pass a car when necessary. The car is sporty and fun to drive, easy to turn, and easy to convert for large items (I brought a huge self-propelled lawnmower home in the back of the car last week). My mileage is averaging 24.5 mpg. The car is quiet and the radio/CD sounds terrific.
Love, love, love the entire car!
My only improvement recommendation to Honda would be to redesign the little window in the back. It does not aesthetically match the contour of the slope of the roof. In an artist's eye, it just doesn't do justice to the overall appearance of the car.
