I wouldn't be so sure of that... They already discontinued Oldsmobile a couple of years ago, which was the oldest American make still existing back then. Cadillac was already endangered back in the 1990s and we all expected them to close for good. And if you ask me: They should've done it. For me, the last acceptable Cadillac was the 1993-96 Fleetwood and all these awful things they released afterwards (Catera, Escalade, whatever... I've already even been waiting for a Cadillac subcompact, a Cadillac bulldozer or anything worse...) didn't deserve to carry the traditional name Cadillac any more. (Just my point of view)

1902 - 2002 would have been a honorable century to last for such a great make. Better than becoming a caricature of itself, anyway.
