In the real car history, the Mustang brand is way more important and "legendary" than the M3, not to mention that the first M3 came 20 years after the first Ford Mustang.
As a brand it's probably more important in north America, but outside the states the mustang has achieved very little, its well known for no good reason but nothing else. The m3 over the years has pushed the boundarys.
