I've had my Civic Hybrid for 3 and half years now and it still feels nearly as tight as when it was new. My mileage is 50-57 in summer and 42-45 in the cold northern winters. It handles great in the turns though fully loaded you can tell the difference. It is a nice smooth and quiet car that driven lightly will get outstanding mileage in town. Two gripes only. The electric power steering doesn't have a good sense of feel or on-center and will drift if twitched even the smallest bit. Winter warm-up of the battery/hybrid system takes way too long and drops the car's mileage a lot in winter. That said, I think it's a great ride that has really taken the pain out of the high gas prices.
Gas mileage. Great handling. Quiet. Solidly built, high durability.
Steering feel is poor and easily drifts off straight line (before and after dealer alignment).
