Yeah It Happened To My Friend When I Was In The Car We Were Coming Back From Atlanta And He Was In The Triple Digit MPH's And We Heard A Loud Thud The Sunroof Had Come Off And The Headliner Was Pushed Down From The Roof And Hit The Person In The Back Seat Right On Their Head. Our Friend Was Behind Us In An S10 And He Said That The Glass Had Flew Up And Over A Semi And Shattered Behind It. The Glass Was Ripped Of So Hard That It Actually Bent The Metal Frame Of The Sunroof. The Black Stuff Was The Adhesive Of The Glass And That Stuff Was Getting EveryWhere In The Car Also. But I Believe That He Got The Whole Thing the Frame And Glass Off Of Ebay.
