I have news for you. I remember reading in a magazine, that Mercedes has already produced a cabriolet version on the CL and the C Class sports coupe. The Sports coupe was a one off concept vehicle, but the 5 examples of the CL were built and auctioned for charity in Europe. I know that there is a picture in existence, but I can’t find it. It is safe to say, that Mercedes did a much better job that the CL above, with the massive roof being totally submerged under a solid cover, much like that of the CLK.
