I have a hard time turning down old French bikes as well. One of the advantages of living in the US, though, is that the odds of finding anything this old and French are not very good. Finding incomplete bikes isn't hard, though.
I do have a 70s era Motobecane Grand Record I've rebuilt and I have a 70s era Mercier 300 that I will rebuild one of these days.
.... yes. Love or hate - more often than not there's a good bit of both with a French bike
