TB, I just picked up my Z last night. It has both the Touring and Sports packages. With the Nav system, you forfeit the 6-disk CD changer but get a 95 GB Hard Drive to store all your music in.
Mine is empty atm, and I need to spend some time figuring out how it all works. Damn... I should have called in sick today.
EDIT: I also got the 7-speed auto trans, which I'm loving the hell out of already. The - + paddles rock!
