I am saying if there were two cars, one had spoilers and a ZL2 hood and one did not. I would want to find out if the car that had those options came with them. If both cars came with originally with the flat hood, and one car had it added later on, I would take the car that had the original flat hood. AND depending on color for me, if they were the same color and one had a factory ZL2 hood vs the other car of the same color having a flat hood, and everything else being equal, then I would take the ZL2 optioned car.
All I am saying is there are other things that may sway me more than that hood, I am just very fortunate I found the car that i have and it happened to be a car that was ordered with the ZL2 hood so along with the color it fit my criteria for the Z that I wanted.
