In 3 years have opened my sunroof 2 times
On hot days, I will tilt up the sunroof when I park, to try to reduce the heat buildup. But that is about it. I rarely use my sunroof.
In fact, I almost always have the shade closed. Sun through the moonroof just adds glare, and closing the moonroof cover reduces cabin noise slightly.
The Land Cruiser is already an overweight pig. The last thing I want is a pano roof, which would add additional weight up high to an already top-heavy vehicle.
