2005 Mercedes-Benz SL-class SL65 side.jpg

Mercedes' premium roadster may get outhandled by the baby SLK, but definitely not outpowered. Like the CL, the SL gets the same new 604-horsepower, twin-turbo 6.0-liter V12 added to its lineup with the same $180,000 MSRP. Can we call this the ultimate driving machine, or has that been taken?
