I have been selling bikes and parts on CL for 5 years plus now. It is easy to tell the spammers from the actual people that are interested. The fact for me is most of my stuff I end up shipping (parts not the bikes) on CL or here or other forums. I haven't been doing bikes much because I haven't been finding them or the time to work on them. The last bike I sold last week. On Thursday I bought a few year old Diamondback BMX bike at a garage sale for $40. A quick tune up and cleaning and listed on craigslist Friday night for $120. I would have taken $80 for a quick double of my money, but ended up getting $100 for it on Sunday. Not bad for a quick $60 in a few days sold to the first (and only) responder.
