There are some cars that we wish could live forever. The Acura Legend comes to mind as one of those, and now the Mercedes SLS AMG GT can be added to that list. Ahead of its unveiling at the upcoming L.A and Tokyo Auto shows, the German automaker has released images of the final edition of this classic roadster. Limited to just 350 units, the Final Edition boasts a 6.3-liter 591-horsepower V8 engine and bespoke bodywork. The SLS will be replaced next year by a new model, codenamed C190, which is said to be go right after the Porsche 911 Turbo when it debuts in 2015.
