I look at what kind of models are selling well these days, and it makes me concerned as to what we will have coming down the used bike pipeline in the coming years. A whole lotta junk, IMO. Even a lot of the high end stuff (all black, of course) looks pretty inferior to bikes built in the 70's, 80's, and 90's. And people only knock off 100 bucks or so, from the original (outrageous) purchase price.
It looks as if the golden age of finding great vintage bikes on CL are basically over, for the foreseeable future. With occasional exceptions, like when a collector with no friends or relatives that ride, dies.
