I think the glass roof vs. no glass roof is something that you either like or don't. I don't like them, and have rented a few cars with them that made me realize they weren't for me. But the AGT came with it. I cursed and figured that the blackest tint I could get would be fine. It is tolerable but I really wish that there was a retractable interior cloth cover like some of the Mercedes SUV's that I had rented with glass canopies. I had HuperOptik i3 ceramic tint installed, and the darkest is about 70% light rejection and 93-99 % IR/UV rejection. It is a vast improvement over not applying the tint but I wish they had a 90% visible light rejection. My 2 teenagers wish I didn't put in the tint and liked the backseat view the way it was, so different strokes for different folks. I think if you know you don't like a glass roof don't waste the money {and then extra money adding tint}, get a metal roof you'll be happy. If you've never tried a glass roof, rent a car for a day that has one. Doesn't matter which brand, the experience of a glass roof will be known to you quickly.
