If you are waiting for the last version of a tuner Mustang you may be waiting awhile. Roush and Saleen will keep making versions as long as they sell. For a long time the tuner versions were outperformed by cheaper factory versions. Only the limited production/expensive models like the P51 and the Saleen Extreme approach factory car performance and are quite a bit more expensive. Their claim to fame is in the handling department. I would expect to see the same thing with the Camaros and Challengers as other tuners will want to tap into the market...
