I think initially many were happy to get a cool old bike and mid range was popular. Also the older group valued them as they were childhood bikes. But now many just want high quality or recognized top names in good condition.

And, so many mid range Italian and other bikes became available from overseas on FaceBook. Steel is Real was kinda like here, people showing cool bikes or finds. Now it seems to be a for sale page. Rarely any new content and everyone sees everything all the time. The magic of mid range and less suffered.
