Welcome to the forums, dpatrickv! Glad to hear of your new XTS purchase. I'd just echo what Raven said, if you're looking for a full-size luxury sedan, you've got one of the best on your hands in terms of being as problem-free as possible. Raven hit all the well-known issues on the head.
Also, and maybe of no consequence (but just curious), what was that GM product you had when you were 16? My first car was a 1998 Olds Cutlass, I loved that thing even though nothing worked except the drivetrain lol (no heat/ac, suspension components constantly breaking, brakes always wearing out, electronics eternally having issues, etc). Memories!
