I need a new car for school and I'm thinking about getting another civic. Good idea or bad idea? Does anyone have any advice on buying? What are your opinions of autotrader/ebay/honda-tech classifieds vs used car dealerships? Should I buy something that is still stock? I probably can't afford much over 7 or $8k.

I'm sure this has been discussed before but I'd rather not dig up and hijack an old thread started by someone else.
