In the UK we can only get the metallic - Comos Black. The night package comes as part of the AMG option in the UK with things like the different body kit, wheels, interior and suspension. i just noticed the price list in the UK has been updated to include the 45AMG.
You should have a look at the UK price list as a comparison so you can see how the different options are split/ marketed based on region.

I was so lucky they had a black one left without options i didn't want already built. I only had to wait 8 days and ended up getting the heated seats and mirror pack for free through negotiation/ bluffing i was willing to wait for one to be built.
I will take more pictures tomorrow when i wash it for second time this week......brake dust on metallic black alloys/rims is a nightmare!
