I'm debating with myself about getting the pano or not. The reason to get it is extra headroom, I'm 185 cm (somewhere between 6' and 6'1") tall. The reasons to not get it is that it is expensive to just get ~2 inches headroom. And it seems to have some problems like creaking, leakage, etc. Can I sit in the drivers seat without my head touching the roof without pano? What about in the back seat (not happening very often)? Any other advice?
