It would be cool to have if it wasn't your daily driver but otherwise, not practical. My step-dad has Saleen S281 that sits in the garage. He takes it out every now and then, burns tires until he hits 55 and cruises down the road. I don't really see the point either.
i saw this about the 2015 Saleen, it reminds me of the camaro. http://blog.caranddriver.com/saleen...r-the-2015-ford-mustang-and-it-looks-bad-ass/
