I've had my Civic for over 2 years and I absolutely love it! Of course, like every car, it has its quirks, but all in all it's a great car. 40,000 rolled up last week, and it's still tight as a drum. It does have several rattles, but they have gone away with time. I LOVE that I only have to change the oil about every 6,500 miles rather than 3,000 (the Maintenance Minder system even tells you when it's time to change the oil). I have the coupe, and the trunk is surprisingly roomy. I do about 90% city driving and get about 34-36 MPG. The car also holds up well in accidents; I've been rear ended and clipped in the front, and both times the car had less than $500 worth of damage.
Digital speedometer, steering wheel audio controls (EX/Si only), GREAT gas mileage, great handling/avoidance maneuvering, and a great stereo system (EX coupe comes with an 8" subwoofer in the rear parcel shelf)
Make it quieter (less wind noise/tire roar), improve the optional fog lamps.
