Well guys, I doubt seriously that we'll ever see the names Cadillac is known for after the next few years. They've gotta compete with the Japanese and more importantly the Germans if they want to survive. Both camps use simple letter and numer combos for their model numbers. BMW's are labeled simply by their numbered series and their engine size. Mercedes is almost the same. Honda used to give it's Acura's names (Legend, Integra, etc.) but now they're all letters and numbers (3.0CL, TSX, RSX) just like the Germans. Cadillac is just following the trend. They've started with the CTS, and the XLR. The Seville according to car and driver is dead, and will be known as only the STS next year when the new model comes out. That only leaves the Deville, which is going to be the oldest chassis in Cadillac's lineup. I expect it just to become the DTS or whatever. I guess the only exception to this is the Escalade, but even then they've got the Escalade ESV.
They may be killing off some of Cadillac's heritage, but times change. If the young people (in general) want Bimmers and Benzes when they get rich, Cadillac's gotta get on their radar. If something as simple as naming their vehicles like their competitors could help them move cars, they'd better do it. Otherwise, it's of course a longshot, but they could end up like Oldsmobile...
