the reason? the windshield is RIGHT there, UNTINTED, and is directly going on the seats.. which = hottttt still..

just my observations

i thuoght about tinting the windshield 50% (about the lightest you can go..) so it would not make it dark, only block out the UV rays.. but have not gnoe that route yet
