Welcome Grolsch30, nice to hear you finally got your up! That was definitely a mammoth wait for you.
I have to admit that those were my initial thoughts when I saw pictures of the sunroof but once I got my car, I just love it. I suppose it's a bit of a cheat in that the "panoramic" bit seems to refer more to the exterior look of the sunroof but in any event, it certainly makes the car seem lighter and even more spacious.
Unfortunately, I haven't had much opportunity to make use of it as it seems to have rained constantly since I collected the car but I'm so glad I opted for it.
Can we see some pictures of your car please. We all love seeing photos of our up!s and yours will (I think) be the first four door we've seen on here.
