Ok I order my 5.0 a while ago and want it with some accessory like the side scoops, 1/4 window louvers and the pedestal spoiler. But the my salesman said that if I wanted those items I would need to buy the GT Coupe Acessory Package 5. Which it inclueds those plus the hood scoop and the decklid trim. He said that I couldn't order it with only the accessory I want it. So is that true or false?
