Welcome to the forums Mat,
Having had a black car before they are an absolute nightmare to keep clean but once they are they look amazing!
Enjoy and don't forget to post a few pictures up, particularly if it's all nice and clean.
Colour is a matter of taste and preference, obviously, and as a designer I am well aware that cars can look very different in the flesh to how they look in pictures and from paint swatches. Consequently I rang around dozens of MB dealers to find out what colour GLAs they had in their showrooms, and then made a point of travelling around until I'd seen every available colour. No contest - it had to be silver, which is to MB what red is to Ferrari. An added bonus to this travelling was that I found out that not all MB dealers are equal on pricing policy. Most followed the rules of their owner-groups and would not discount my car by a single penny. However, not all dealers are equal
