I definitely enjoy having the option to have the roof open. I've been sliding the cover shit more and more recently though. I don't really like being all lit up inside, and it definitely lets more heat in when the cover isn't closed.
I'm glad it has it, but I also enjoyed the added headroom in [MENTION=135317]rkntoy[/MENTION]'s rig when I was in it. I'm not worried about leaks- those can be fixed easily enough.
The added space inside really is noticeable, and if I could option out my "dream 3rd gen", I'm not 100% sure I would add the sunroof.
