My Sixer has 20% all around, its black on black, I wasnt a huge fan of tint before I did it, but Because I live in Florida It was necessary. Not the Car looks so sharp, and I'm very used to it. The only problem is driving in the rain at night, you have to be carefull. As far as legal, THe fronts are not, but the cops in FL arent gonna bust you for that, They know how hot it is. Besides if I ever get pulled over, I'll just lower the front windows. But The car looks great, the rear windows are really big and if I see a sixer without tint I think they look kinda goofy. It definatley keeps the car cooler. and I'm sure it helps the rear leather and back pods. I always use a sun visor over the windshield. Hope this helps.
