Hi kateblundell,
I do not have open sky, but I also do not have a black interior. I specified a beige interior as I liked the look of it from the brochures and do not regret it. I have sat in an A2 with a black interior and no open sky and I know what AMG means when he describes it as claustrophobic. I was gob smacked. I cannot say that my beige interior is claustrophobic; filthy in places, yes, but a good clean brings it up a treat.
John.
