Yeah, we thought about just getting enough tint to block out heat/UV (70% I believe it's called) w/o darkening, since I'm not a fan of the dark window look, but we're holding off till later once we see how it is w/o it. So far the glass roof has been no issue, even in the minor heat wave we have occurring (at least according to my BF, who shaves his head, so if anyone would feel it he would!).
FYI they also do partial PPF - I just opted for full since this will be my primary car.
Oh, and the 'Nice Tesla!' and stares have already begun while tooling around town in the Y. Lots of smiles. =)
