Some CL buyers/sellers must live in a world that moves at a snails pace, even in SoCal.
I list an item for sale. E mail says, can I come look at it a week from Tuesday? ummmm, If I have any idea what I am doing this bike it will be sold by tomorrow.
As mentioned by bigbossman it is difficult sometimes to give your money to someone that is selling what you want. I guess you can't expect too much since humans with a low IQ are not excluded from free classifieds.

It is refreshing when you get someone on the phone, you tell them the BB on this steel lugged frame has been overhauled and they know what it means.
