Good night, sweet luxo-barge. After nearly 10 years in production, the 430’s sales have fallen from about 14k in its first several years on sale to 720 units last year and about 2k units the year before that. Which, for a rather ungainly and quite expensive boulevardier, is not half bad at all. It will never be a car that enjoys enthusiast or collector cachet, but cougars and their plastic surgeons alike appreciate its smooth power, anonymously ostentatious looks, and old-school personal luxury coupe style. In short, it’s been the closest thing to an old-school Buick Riviera on the US market in decades. And as of July it will be gone forever.
