Wow okay. Well thanks for pointing me to the hidden photo of the gray/wood combo. I guess my imagination wasn't far off and that it doesn't work very well, at least to my tastes.
It looks like aluminum is the only way to go with a gray interior. I think black interior gives it that classic BMW look but 1) I don't particularly like black inside in general, even though BMW's pull it off well and 2) With an SG exterior I think the whole car would just be a bit too dark.
I'm also waiting to see the SG in person. If its too dark in person then I guess I'll switch to old reliable (and common) TiAg/Black/Aluminum and get on with it then
