I have a "shade" tint across my windshield at the top.  It comes about 4" down from the roof and is the darkest limo-tint available.  That is probably the most appreciated tint of all my windows.  You can still see through at all the beautiful mountains and trees and stars, etc. but late in the afternoon or early morning when the sun is low and right in your eyes, that tint is a wonderful thing.  I had a big "Header" decal on the windshield of my racecar, mandated advertising for one of my few sponsors, and I loved that so I tried the limo tint on the van windshield and it works great, too.
