AMG is a company, a brand (such as Roush or Shelby) that takes Mercedes cars and then customizes them. Just exactly like Shelby, Roush, SVT, Steeda and Lingenfelter.

Wickey, I agree. But in my opinion, American cars rule everything. I think this because I do not give a shit about reliability, handling, economy and quality. So, Benz just does not have anything good aside from those things. Speed, sure, but the only fast ones are so insanely high in price, it just makes you want to go out and buy that $41,000 GT-500 (and walk away with $100,000 that would not be there if you bought a AMG Benz).
