Though I haven't seen one in person either(Dealers say some time around May). From the official released pics, S600 has different wheel(looks like Lorinser wheel, but at least 17"), side sills and rear bumper is a bit different. S600 also has chrome exhaust tips like CL-Class, and "V12" badge has move from C-Pillar to front fender, just behind front wheel, on the side body strips.....
Performance wise, I doubt it that S600 will be any faster than S55 AMG. Both should be about the same, but I would go for S55 AMG for its look/performance....
