You guys do realize this is just a name that came from an online contest, to rename the performance package? This isn't some new model, and frankly I think the name is kind of stupid. I think they should have just stuck with "Performance Package".
I just can't imagine driving around in a "Mayhem" Mustang anymore than a "Transformers" Camaro, but then again, I'm not 18 anymore either.
I can't believe people are saying there are too many models of Mustang to choose from. It seems better than the alternative. And being at the end of it's life cycle, the Mustang can afford to do these kind of things. It's great for the enthusiast, so I don't see a negative to it.
