Another perspective, from the seller's end -

I just tried to sell my 2007 54cm Trek 2100 WSD on Craigslist, and was very disappointed with the experience. I got a few "bites", but one turned out to be a "scam"...thank goodness I was able to detect that this guy was scamming me and just trying to get my personal information. I had a few genuine interested parties that emailed me for more information/pics...which I gladly provided to each and every one of them. I did have one actual offer, but the guy low-balled me so badly...basically wanted me to give my bike away. When all was said and done...no sale resulted. I guess I'll try listing in a month or so, as we get closer to springtime.
