Black Trim Question

[bsklar]

I have ordered a Space Grey 4.8 sport with many other options. I did not know if the car would come with chrome or blacked out trim. I originally thought that this was based on sport or non-sport models. However, I saw a 3.0 (see space gray picture) and a 4.8 (see black picture) on the dealer's lot today. Neither of them were sport models. Both had rear climate packages with the privacy glass. The space grey 3.0 was blacked out, the black 4.8 had chrome. Now I am confused. Is it that all 3.0s are blacked out and all 4.8s have chrome??
