They look very similar but I'm not sure. The standard Avantgarde ones are only 16" aren't they and in the catalogue it shows that they make 16" and 17" just like the Merc option list so I would probably say yes they are the same.

Just compared the two...they are identical to me...no wonder I've seen some on Non-MBz cars and thought...."wait a minute..isn't that....." So i guess either Mbz copied or Dezent replicated.
