To tell the truth I would get a Z06 twice over this but you cant really compare the two. This Cobra is mainly going to an all out fire-breathing, burnout competition winning muscle car except it can take corners and stop. The Z06 is in another class altogether. It will basically be the ultimate Corvette and stomp on just about anything at the track. The technology put into that car far surpsses the Mustang's. It will not be 70-80K as someone else sated but it will be expensive.
All I know for sure is that it is great time for American performance.
