RE: -=OFFICIAL HPI FIRESTORM THREAD=-
Hobbies, crafts. People in my area usually search for nitro or radio control because there isn't a specific category. I sold three trucks in one day last month and only advertised two of them! The two posted trucks sold about a week after posting and I had five people seriously interested and I ended up finishing another truck up for one of the other guys. Other trucks have sat there for a few months - its hit and miss.
Try Craigs list as well.
