My sainted grandmother bought a new Cadillac CTS in November 2002, when they first came out. 60,000 miles and only one tow in because of an ignition issue. No other problems that I can recall. Plenty of granny marks, though, even after multiple bumper repaints.
I got the SL at 16, and she continued driving my late grandfathers mid-90's Seville until upgrading to the 2003 CTS. She gave the Cadillac to my uncle, the head cracking a few years later after he overheated it. He does have a tendancy to abuse cars, and watching him slowly destroy my grandfather's car was kind of disheartening.
