That's the colour I have on my current car, and I absolutely love it! It keeps me motivated to clean my car more often.
Btw, I understand that you ordered your car this week, and the order is already locked now. I ordered my F20 in November and it's still not locked! I asked my dealer how this could be possible. If I understood him correctly, 116d is so popular that they basically just order them before the customer has asked for it. So when they get a customer, they update the order according to the customer's wishes. I don't know if I understood him correctly or if it's even true, but it could be a plausible explanation.
I don't think they sell many 120d's, so I'm in for a long wait. At first I was told mid February, then late February, then maybe late February. The latter is the last information I got, and I interpret it as "mid March". I also read that BMW are experiencing delays due to lack of parts for the sports automatic, so maybe it'll be April before I have my car.
