All it has is some 'bumblebee style' rallies and a few autobot stick on emblems? Not even different paint? I don't think this car will be terribly collectible, but hey either way you won a free Camaro, so congrats!
P.S. I found these: on the internet
and I would guess that they will be quite similar to the badges they put on your car. ($4.99 for 2 on ebay)
