Mercedes-Benz has released a new topless version of their vintage-inspired coupe, the 2012 Mercedes-Benz SLS AMG Roadster.  It’s the famed gullwing roadster without the gullwings, replaced instead by a convertible top for breezy summer driving.  Under the hood, the same 571 HP heartbeat has this SLS pushing neck-breaking acceleration numbers, all the while maintaining the interior luxury of its hard-covered twin.
