I Dont Consider Rattling Bolts Loose, Window Not Glued Tight Or Anything Like That Causing The Window To Break A Big Deal, Let Me Hear About A Good Condition Auto With A Damn Loud System That Flexes The Glass To The Braking Point, Now That Is Impressive, Havent Seen It Yet In My Days, And I Have Been Doing This Since Most Of You Were In Diapers, Yea I Have Seen The Seems Blown Out Then The Glass Bounce Across The Hood And On The Ground, But Never A Window Explode Like Rock Has Been Tossed Thru It....
