I have never bought a car (except a convertible) w/o one; it’s one of three absolute requirements in a car for me. I use it all the time. I’ve ruled out cars because I can’t get one or at least not for a reasonable price. One car it was a $15,000 option - okay it was only a $2500 option but one had to go up three trim levels to even have it as an available option; getting one w/ a sunroof was $15,000 more than the base & probably $20,000 over the life of the car due to a different engine in the higher model.
Tilt it open a bit in the summer when it’s sitting in the parking lot & the hottest air goes right out making it not so hot when I go to get in it. Except for the defroster I hardly ever use the air conditioner, windows & sunroof are open so I get glorious fresh air most months; even a decent winter day it gets opened On rainy days I’ll use the tilt function so that I get air flow w/o getting wet.
The shade is almost always open letting in additional light on all but a few of the hottest days & the opening begins behind my face so it doesn’t typically cause any glare.
Yes, there was a time when with aftermarket sunroofs it wasn’t if they’d leak but when; however, I believe they are better now but didn’t get much of a response when I asked about them a few years ago
