Too many tuner/design shops are coming out with packages that are just too similar. Saleen. Steeda. Roush. Shelby. Etc. I do give Shelby credit for doing something with the '6' at a time when fuel economy is a focus, but I have to wonder how well it would accepted by the true muscle car crowd. It wasn't long ago that a good idea called the Prowler bombed mainly because of its 6-cylinder powerplant and subsequent soft-toned image. When the new GT500 comes out most of them are going to see a grinding halt in their sales IMO. Even though I'm not crazy about the new platform. JMO.
