@sedecrem
for sure the one you've posted is a photoshoped nose on a R230, look at the side of the car and the A-pillar
the one i posted is a "concept" and is not the final approved design yet but it's got the most votes internally at MB (don't ask how i know).
I have not paid much attention to the upcoming Cl to be honest but i'll try to find out if it'll come in cabrio.
