>>1934142this red bike for example, has a campagnolo seatpost. That is as far as they decided to spring the money for campagnolo.
you're gonna see far more of the shitty entry level campagnolo of that ~late 80s/90s era but i don't think that campagnolo is really special at all, you just might get some nice wheels on a bike with it.
As for vintage campagnolo like pic rel, gorgeous, yes, but also ridiculous and absolutely shitter than basic japanese equipment that's newer.
