Sold my (2005 hybrid tt) on there too back in 2012. Got $2000 more than what they were giving me as the trade-in. Had it listed for about 4 months, but on the day I put down a deposit on my new tt, someone called to look at it, and bought it. That was cool.
I sell / flip a lot of stuff on Craigs.
Enough to supplement my nearly retirement.
