Looks good! Any accents you do will only help to set the car off even more. I too was thinking the berger panel might look cool on there. I thought it would coordinate well with the top. Or get the black Camaro lettering to fill those recessed letters.
As for that color, it was a special option on the 5th gens. As Jim stated, originally only on the V6 cars for 2010 as part of a 'green' high mileage package. But for 2011 they have changed it so you can get it on the SS too. The color is awesome. It totally pops in the sun. There is one in the parking deck at work here and on a sunny day it reflects a lot of green in that area of the garage. :lol:
