There you go, guidance from $350 to $1,000! The low side feels like a local CL “just move it” price and the high side a throw it on eBay for that lucky overseas sale.
If you’ve been watching values, you already know vintage bikes have slowed to a crawl. Best to hold on to it and enjoy it if you can. If you’re committed to selling, I think it could sell locally somewhere in the 4s. Campy on a clean bike can still do okay. It might look like listing at $475 and waiting until someone comes along who will give you $425-$450. My 2c.
