Mercedes planning CL-Class convertible?

Mercedes may be planning a convertible version of 2007 CL-Class coupe, according to Germany's Auto Motor und Sport. The magazine report stems from a conversion with DaimlerChrysler's Hans Dieter Multhaupt. Such a vehicle would conceivably be similar the the BMW 6-Series convertible, however its price point would be much higher. It would likely be priced above SL-Class roadster, as the CL coupe is already pricier than the two-seater. Mercedes is also rumored to be planning a four-door S-Class convertible.
