Sorry to hear Scott.
It is not GM's fault for damage in shipping, but they and/or the dealer and/or the trucking company will get it fixed. It is a car, but it is the same when UPS or FedEx damages a package during shipping. Unfortunately it does happen. It's like the old phrase "That's like trying to blame Ronald McDonald for a bad burger..." just a goofy phrase, but it has merit.
Just bummed it was Scott and Steph.
