Dan...Just picked up my first GM ever. Always driven ford, from trucks, to mustang's, but here lately with Fords decision to go cheap, and my need for power, reliability, and gas concerns I decided to check out some GM cars, and before the day was over I was driving my 02 GTP sedan. Damn thing is fully loaded minus a sunroof...I still am excited about the HUD...not that I need it, but it's really cool. Well if anyone has some easy info for maintainence, improvements, common problems, or just facts about my car I should know I would really appreciate it. I look around online for info, but there is no better place to learn that from those who are in them every day. Thanks
