I would have loved to have gone with the 20%. Am a bit jeolous.
But I really worried about seeing out at night or having a "cave-like" interior as I also have black leather etc... How is your view out the windows at night like when backing up? (Yes, before everyone says... I know it has a camera, but I'm old-school coming from an era when you actually had to look out and turn your head)
I might go back an have the back tailgate window tinted over the factory. Driving at night with the electro-chromatic mirror, the mirror doesn't darken enough and the headlights shining in back bother me.
