Not that I know of unless some flying clubs or aviation buffs still have a few in flying condition but this nothing I have heard of. I am sure there are Caravelle groups to be found on the Web maybe on Facebook.
To answer your first question, yes I keep excellent memories of flying in the Caravelles. They were the precursors to Concorde which original name given by Sud-Aviation was "Super Caravelle" which had later become Concorde as named by General de Gaulle.
This was in the 60's way before the French Revolution of 1968. I was mostly with my aunt and my cousin. I remember being served full meals on board that included lobster and champagne. This was in regular class not First. They did not have the name Economy class in those days. They had another name for it which I can't remember.
It was the flying of yesteryears.
