Simply personal preference. The two Scenics I used to drive both had sunroofs (wide, not panoramic), but the Berlingo that followed it didn't. I always found the interior dark and depressing. As it happens, that car was written off within a year (not my fault - it was parked at the time), and the replacement had a double non-opening sun-roof. Immediately, I felt a lot better about the car. I like light.I can't quite understand these panoramic sunroofs, cars get hot enough as it is without turning it into a greenhouse, make far more sense to make it a solar panel.
