I have this combo...
I always had black on black trim on black roof (damn I miss my E46
).
Time for change, and i don't regret it 1 minute!
You had more of a cocoon feel with the black interior. Now it's so spacious, I think it's great!
I chose for the aluminum because the wood trim's makes it an old man's car in combo with the beige...
1 year and 60.000 km later, i still think it's a very nice combo!
