Hello,I am A new Grand Prix owner of A 2004 GT with 127k on it. I think it is a wonderful car and hope it is going to be fun learning more about it on this site. Anyone have any tips I may use? I did see that I may need to change the head gasket with 127k on it or do i wait tell it blows? Probably the wrong place for this first post huh?lol I will learn!
