I'm not a big CL seller so I can't comment on buyers. Basically I'm just buying for parts or to add an occassional bike to the collection. I'd rather sell my good on ebay and avoid the face to face contact.
I'm not anymore either.
Our family has an ample supply of bikes, and that was the original goal.
Goal was achieved a couple of years ago though, and the rest is gravy at this point.
