That's very true, I never really considered it such an important issue, but thinking about it, it really is.
Did you bother to get tints on your Magna's, or do you think this would be unneeded? Some seem to recommend them, while others not so much. I am extremely surprised at the number of vehicles in Australia that do have tinted windows though. They seem to be a common sight, compared to here in New Zealand, where they tend to be a rarity.
