The newly designed Cadillac STS is entering dangerous waters. Seniors everywhere who liked the STS the way it was will not be happy with this hipster version emulating the popular CTS. So what does the Canadian GM arm do? It writes and publishes a book called "Hello Cadillac STS, Goodbye Anonymity," available online only. Grandchildren everywhere are being asked to figure out that darn Internet thing so potential buyers might even consider trading up to the more advanced and stylish new model.
