Well, make sure you get insurance when renting!
I am not worried, GM will look at and resolve the issue. Besides, look at the underneath area of the fascia, it looks as if it might have been hit. There is not enough view of the entire bumper to see if it was tagged.
The Corvette has been in production for years. Each time a new model comes out it has it's own issues. The Camaro will follow suit.
GM, here is a big one for you. Just tell us soon what the plan will be.
