After giving the world the Black Series CLK at the New York Auto show as a fortieth birthday present, the gang at AMG are at it again. A very special Mercedes-Benz SL has been spotted being prepared at AMG's Nürburgring shop. Like the CLK, the SL gets modified bodywork to cover the steamroller tires and will undoubtedly get an extra helping of power. So far there's no word on when we'll see it officially or how much power it will have, but the smart money is on something involving a "63" badge on the boot.
