For those of you that have the panorama roof, do you guys get a lot of rattles and squeaks from the roof. Over bumps and uneven roads and also when the body of the car flexes (going up the driveway), I get a lot of creaks and squeaks and sometimes loud cracking noises. I have less than 10,000 miles on the car and the roof is very noisy. I wouldn't expect this from a $50K+ mercedes. I don't know if its because of the large glass area or if I need new seals around the glass. PLEASE HELP
