I spent three weeks in France, in Paris, Pau and Burgundy. I saw many an odd car there: Daihatsus, Skodas, Ladas, Austins, NSUs and Wartburgs. I saw Chevrolets, Opels, Vauxhalls, a Buick and even an aged Pontiac, though it was sitting up on blocks. I did NOT see a single Cadillac. I did see the turnoff to the town of Cadillac on the highway between Pau and Bordeaux, but if there is a market for Cadillacs in France, it is recent.
I don't really like the persona in this commercial, he is a smug prick, but since there are many such smug pricks with money, it makes sense for Cadillac to cater to them.
