What tires come on the SS? Are they Z rated? Those 18 inch rims look sweet on the SS. I got a redline only because I got it for about $9k less than i could have got an SS but i still like the styling more on the SS. If anyone is willing to travel to find an SS, head to western PA. I have seen at least one or two in every dealership here. When i checked them out, i thought they would all be spoken for already but they weren't.
