I think that any kind of "rally/support/advocacy/purchase" of this Camaro with a prescence of every generation at the said event would be huge for "GM/those who do not own one at the time", because the influence would be great. I mean, this car is not even out yet and there is a marketed sweeptakes to possibly own one!
Publicity would/
WILL definetly gain
HUGE notariety for this car.
