I have a black 2005 G6 GT. I've had it since March and like it ok. I thought I would love it, I love the way it looks and drives, but as for problems with it, I'm not loving the problems. Since March I've had to get a new door speaker and a new amp. I have the Monsoon system. Yesterday I had to go to the dealership for this rattle that they can't seem to hear and to see if they could fix the door because it's coming apart. My G6 only has 4000 miles on it. I am glad I found this site because now I see other people seem to have the same rattle as I do.
