Thanks all for your very helpful feedback!
I placed my order today for the 2009 128i with Monaco Blue Metallic Paint, Savanna Beige Boston Leather, and Gray Poplar Wood Trim.
The trim turned out to be the tough part.. I had dark burl trim in my '2000 328CI and I loved it, but the only burl trim on the 128 was the light colored type and I didn't think it was quite the same. I'm hoping the Gray Poplar will look good on Savanna Beige... I guess we'll see!
