I have a 12 sport that I love. It came with the freedom hardtop that was great on the colder days this spring. I orderd a trektop nx back in march and just got it on earlier this month. It's nice but still a very tight fit. Yesterday comming home from work I was thinking it would be great if the hardtop had camper style sliding or removable side Windows and a removable back window. It would just be way easier than dealing with zippers and finding storage for the hardtop plus if the Windows were out and freedom panels off it would almost be as open as the trektop nx.

 

Sliding windows would be nice in the 2dr. I'm really surprised that no vendor has come up with a window kit for the hardtops.

 

I have seen a write up where someone installed sliding rear windows. Looked good.
