I really wanted the panoramic roof, I sat in a non pano GTD and a GTE with panoramic for comparison in 2017 before ordering my GTD.
The problem was, I’m quite tall and whilst there was head room (just), it made the car feel small and claustrophobic. I’d like to have driven one with the roof to be sure as this was in a showroom so maybe why it felt this way. I opted for dynaudio instead in the end.
Fast forward to 2021, I really wanted the roof again on the CS45, but nowhere had even a normal golf I could try to judge if it’s ok and decided not to take the risk. One salesman said that the headroom loss was more or less identical to the mk7/7.5.
