Like UK said, this photoshopped pic has been floating around for awhile - ever since the new SL debuted basically. It'll be a few years yet before an all new SLK debuts, and what it will look like remains to be seen, pardon the pun .
This pic whas used by Auto Bild a car magazine that did know howe the E lookt a year befor it was released and they are the Nr1 in spy pic's and fotoshops that come true. But Mercedes hase a new designer so the New slk can be totally different.
As said above, this is a picture that pops up on the boards and in magazines every few months for the past year or so. It was even in a recent issue of "The Star" -- the magazine of Mercedes-Benz Club of America as the next SLK! But its origin remains obscure, and fairly reliable sources say the 6.3 just isn't going to be. Most sources say the new-design SLK will be introduced in '11, as a '12 model. Frankly, I don't think anybody knows what it will look like.
