I have owned this car for a little over 2 years now. I bought it for getting to work and college, as well as cheap insurance. The Civic is pretty slow, and I usually have to rev into 4-5k RPM to make it to freeway speeds by the time I need to merge. Freeway passing is slow, unless you downshift to 4th. Gas mileage is good, but not the greatest, but one of the better ones at the price. I haven't had any major mechanical issues, just a broken power door lock actuator which was fixed under the extended warranty. Maintenance is a breeze. Interior breaks and scratches easily. Good view out the rear. It gets you from A to B, which is its intended purpose.
Exterior. Gas mileage, cheap insurance. No major mechanical issues in my experience.
I put in a short shifter for well... shorter throws. I also updated the stereo system. Fabricated brighter dash lights to be able to read them easier. Needs better tires, suspension. Most of the complaints I have are irrelevant because the car does what I need it to do.
