Carbon black vs. jet black

[MBrown1003@xxxxxxx]

The order on my M5 is in, but I'm waffling about the color -- Jet Black (this 
would be my 6th black car, so I know what I'm getting myself into!) or Cosmos 
Black.

The Cosmos is an extremely dark blue metallic.  At night, or from a distance, 
it appears black.  Up close, when brightly lit, it appears sapphire blue.

Anybody out there got the Cosmos?  Whattayathink of it?  I've heard it looks 
dusty when clean -- is this so?  Also, I've never had a car with metallic 
paint -- how hard is it to care for?  (Remember, my basis for comparison is 
black!)

Thanks, everyone.
