I was driving my sister's '06 Z71 Burban last week and noticed a quarter-sized hole on the left side of the front bumper. She had backed into it with their other Burban the week before. I have a neighbor in VA that owns a chevy dealership, so I took it in for a look-see. The bumpers on the new suburbans are held on by several PLASTIC pins. She had dislodged one, even though the contact didn't even scratch the paint on either of the glossy maroon vehicles. They popped a new one in and away we went. A break-away bumper in a 6K lb vehicle doesn't seem like a good idea to me.......
