Do a search for tsb (technical service bulliten). There will be some links to web sites with your answers. Other than that I'd say musty smelling ac, clutch chatter, and rusty rotors are big probs that I can remember but easily fixed by the dealership, actually if you are buying new then the dealership should have allready fixed these. The car is an excellent buy so get one and enjoy. Consumer reports loved the car if thats any help. Definately get the 5speed, I didn't have a choice since I'm married and it's not my car. I have a supped up civic so all is well. Also, if you are buying new you should get around 4 grand off the sticker price.
