I’ve got to be honest, but I often forget to use the sunroof. It’s nice for extra light although I often find myself closing the blind on the pano roof for some additional shade on the cabin especially if it’s going to be parked up on a hot/sunny day.
Also useful to cool down the cabin quickly on a hot day when you first get in, but soon end up back using the air conditioning after a few minutes.
I think in the last convertible I had, I used to drop the roof when it was above about 10c, although with heated seats and airscarf it’s probably less of an issue.
It’s a classic British phenomenon, the cabriolet/convertible - we buy more of them here than most European countries IIRC and it’s usually raining, too cold or too hot!
But then cars that make sense are seldom interesting or fun
