I stopped by my dealer yesterday - they received the Barrique Red 330i they had on order. I wouldn't consider it a brown (or "root-beer") color at all. It's definately a shade of red - a very unique shade of red. Reminds me of a lipstick color.
I plan to take some photos of it this weekend and post them. The car hadn't been cleaned up yet, so it was a bit dirty. I think once they clean it up, it will look great.
I'll have to say, I think I like it. This particular one had a beige, non-sport interior, which I didn't particularly care for. I would definately get the gray leather sport seats, myself.
