I showed the picture to my friend who is a grey-market Jap engine importer (Skyline). He is very familiar with hotrodding trends unique to Japan. He (not I), believes AMG is being copied in Japan. Similar to the AMG-type wheels sold by Performance Products or Tire Rack except they copy the logo as well. I am NOT saying AMG isn't working with Mitsubishi. But he did show me a fake Edelbrock valve cover that came on a GTR engine. On it was stamped MADE IN USA. He said an island near Korea was renamed Usa for the sole purpose of saying USA on it's products.
Sounds like a good plot for a Oliver Stone movie.
