Okay well I sort of take that back. I usually drive around w/ my driver & pass. window down... But if I let my car sit out in the FL sun and heat (tint also helps w/ heat I think?) it still gets hot as hell w/ the windows up and I can barely touch the buttons on my dash lol. I can't imagine not having tint on any of my cars anymore, it was OK back up in NH but as soon as I moved down here I got it installed for 100 bucks. Best modification ever
