Yes, you are right..only SLK55 AMGs Black Edition have a
carbonfibre roof and no folding mechanism to reduce weight and make
it more powerful..can even specify carbon-ceramics brakes for track
use..it's limited edition and SO, it doesn't mean no CF roof, not
SLK55 AMG..normal SLK55 AMGs still have a normal steel folding
roof.. 
And I agree Vanquish takes AWESOME pictures!! LOL..rock on!! Post
more stunning pics..and I especially like the Aston Martin DB9
pictures you took..
