JJ,
MB has been producing smoke silver for years. That means there is a certain following to that colour. I think it is a pretty colour and it is definitely my top choice. My SL is white, smoke silver will be my choice if I am in the market for a SL again.

Black is great only if you take care of it. My ML is black and it is a pain to keep it looking good. If I have to do it again, I will not have another vehicle in black.

Buy the one you like. Not what the dealer tells you. You are the one drives the car and have to live with it.
