Here is why I ordered a 2SS without the RS package:
High-intensity discharge headlamps - I like the regular headlights and foglights
Spoiler - I get this with the SS package
20-inch midnight silver aluminum wheels - I wanted the polished Rims
Body-colored roof ditch moldings -My car will be black
Darker tail lamps - Can get them latter
Red SS Badge - I think the silver will look better
If it was priced less I might have got the package.
