I agree: the chrome trim around the tail lights on the 50th Anniversary package makes the back end look more finished to me.I never cared for the "goggles" look of the black panel inside the wrap-around painted edge. It may be iconic Mustang, but it's also kinda uni-brow to me. (I.e., the black panel spanning the tail lights.)

Don't know if I should keep this on or not, don't get me wrong its a work of art but it makes the car look like a gypsy waggon.
