I have the glass roof and expected to have it tinted or to buy a cover for it but haven’t done so in the almost 3 years I’ve had it. If your concern is heat, it’s not an issue as whatever tint they have built in works quite well at rejecting heat. If it’s weight or something else, well I don’t have much to offer there.Once they get rid of the glass roofs I may consider buying one.
I don’t even notice it, the rear seat passengers get to enjoy the open feeling more but it’s hardly noticeable from the front seat.
