They now have the Stage 1,2 and 3 Roush cars. All have full factory warranty and have passed federal emissions standards. The start out with a base Mustang just like Saleen does. They offer different options, much like the factory and Saleen does. They have to meet the federal standards of a vehicle manufacturer, unlike say Steeda which is a "tuner car". Even though the Steeda cars have full factory warranty. I think a lot of it comes down to volume. If you exceed a certain volume of production then you must meet manufacturer standards as opposed to being a "tuner car". Lingenfelter and Henessey are "tuner cars". They are not considered a automobile manufacturer. This is my understanding of it. If I am wrong, I am sure that someone will be more than happy to point out the error lol.What vehicle does/did Roush manufacture? I thought they've always bought some mustangs and threw some of their performance parts on it and then labeled it as their own. If that's the case then I have a '95 SVE GT. Does Roush have a car their own like how Saleen has the s7 or whatever?
