I have a new '15 Reserve. Overall, I think it's very smooth and quiet on the highway -- that is up until about 75-80 mph. Near 80, I get some wind noise from the panoramic roof area. I've never had a panoramic roof previously. Is this common? I've had many moon roofs, and never had an issue. Everything is closed tight. When washing, I did notice the rear glass panel sits slightly higher than the front? I'd honestly rather not have the glass roof, but it was standard on the Reserve.
