I noticed a big drop in the number of cars for sale by owner when they started charging for them as well as an increase in the quality of cars listed on there, there was typically 1200+ cars in there at any given time, every day stuff was re-listed so fast that I would list a car and the next day it was burried pages deep, this morning there was 266 total FSBO cars listed. I hated that they were charginig for it, now I am happy to pay a few bucks, I get more calls because there is less garbage listed for people to weed through to find mine as well as the fact there is less competition.
