SG and AW look awesome with FR interior. IMO the advantage of black is that it goes with any colour combination, the disadvantage is that an all black interior can be a pretty drab environment. My Jetta is all black inside and seven years of it made me want a change real bad.
I guess another factor in the FR's favour is that it probably comes close to neutralizing the hideous orange of the various radio and dash displays.
SG and IB were the two colours I really considered, I think if I got SG it would have been the FR interior. When I decided on the IB I chickened out on the "Superman" car, although I was intrigued, and went with bamboo.
