This is from the 1967 Jean-Luc Godard (not the face-palming Enterprise captain) movie La Week-End. I saw it years ago and I know it's a masterpiece of French New Wave cinema, but all I remember is how many amazing cars it has.
Of course, lots of those cars end up wrecked and on fire, but still. Minis, Panhards, P1800s, NSUs, Dauphines, Citröens, Jags, even an American car or two, it a great set of mid '60s iron. Oh, the end has a sort of gruesome wreck scene, so, maybe just quit before it gets ugly.
