Bought a 2003 civic coupe with 130k on it from craigslist. Paid $3000, the woman had done the timing belt, water pump and clutch at 110k. Drives like a dream, not to mention gets 35+ mpg.
You gotta find cars owned by old women, they dont beat on them and USUALLY get all the preventive maintenance done on them. This lady had a binder full of paperwork: everything from oil changes to timing belts
