Well, I just wanted to say that I have had my G6 GT four months now, and I have had NO problems with noises from the panoramic sunroof, or leaks or anything like that. My only gripe with the car at all is the fact that you cannot manually turn on the dome light in the back seat, as there is no knob. The only way the light goes on is by opening the door, which would be unsafe on the highway I love this car, and would recommend it to anybody that is interested. By the way, mine has all the options other than XM and the side curtain air bags. A little over priced? Maybe, but I did get the supplier discount, as well as a little known discount of $1000 because we also own a Subaru. I'm not sure that this is still available, but it is worth asking about. You just have to show current registration on a foreign car, and bam, another $1000 off.
