To be clear, that's a w220 s-class (early 2000's). There is no s500 amg, only s55 amg, s63 amg, and i believe s65 amg
So either that guy only has a factory issued amg body kit/styling, or is just an even bigger poser For slapping an amg logo on there to seem cool.
Either Way... shit like that just makes me shake my head!
