Those are one of the 3 identifiers of a 4.8 vs 3.0 car (the chrome window trim). The front has the Titanium Kidneys, the rear the larger chrome exhaust tips and the side is the window trim. Of course on Sport Package models the chrome side trim is replaced, but unlike the non-sport 4.8 wheels (which look VERY similar to both wheels offered on the 3.0) the sport package 4.8 wheels (in both 19 and 20 sizes) are different enough to know them when you see them.
