I think it looks great. I think the reason that they do not put the third brake light into the spoiler is because LS and LT models do not have spoilers unless you opt for the RS package. It would be more expensive to have two completely different set ups, and the price would be added to the price of all camaros. More difference between models = high price tags all around! as far as the shark fin, i like its location in the middle of the trunk lid, just not suuuper sure i like how its going to block a bulb or two from the 3rd brake light. The key i suspect will be painted body color very shortly after purchased for a lot of people. It should be under the emblem i think, but again, that would be a whole new emblem set up, rather than slapping a coupe emblem on it.
theres my 2 cents
