Surprising choice. One would expect a more contrasting color in combination with AMG, panoramic roof and black interior. Mind you, I like a black exterior too, my all time favorite by far, but again in combination with AMG and pano... I don't know. The thing is I see the W212 with the AMG sports package all the time nowadays and the ones in black, well... you don't see it's an AMG until you're really up close. The lines in the front somewhat blend together preventing you from picking up the more aggressive styling of AMG. The same applies to pano, you can't really tell if it's a pano roof unless the colors really contrast. If the car is parked however, it's stunning. Aggressive styling combined with an aggressive color. Absolutely beautiful. It's just that you don't pick up the same look once the car is driving.
Again... love black... drive a black, albeit the limited Columbite Black, 2009 W211 right now in Avantgarde trim, without AMG package. And in combination with a non-AMG W212 I would opt for Obsidian Black too.
I'm in the market now to buy a new MB. I will most likely stick with the E-Class (love the Coupe but that's a C-Class really) and will opt for a more aggressive appearance this time. White is a favorite, especially since Diamond White - at a hefty premium - has now become available on the sedan as well, but lowers the resale value here in Europe. So I'll probably opt for Iridium Silver in combination with Avantgarde, AMG and pano. And black sports interior - as classic as one can go really. Make it a classic "Silberpfeil"(Silver Arrow). Uber classic I know, but the pano and AMG will add a nice touch.
Enjoy your W212. I'm sure I will.
