Hello - I just bought a 2004 Grand Prix GTP, Special Edition after being a 3x, 10-year loyal Saturn owner. I'm looking forward to having some fun and enjoying a nice big car with that something extra under the hood. I haven't found much online about the GTP Special Edition and welcome comments from similar owners - any quirks to be aware of? Also, what exactly does the "special edition" in addition to the GTP package, mean? Are there any particular TSBs that seem more important than others? I still have a little time on warranty so I want to be sure it's up to par. Thank you!
