Best thing about Ford (I know, it's a surprise that one exists): The Roush Mustang is fully backed by the original Ford Warranty. That's why it is surprising that you don't see as many Roushs and you do Saleens. Roush has over 300 changed components and the Ford warranty, but the Saleen has less than 100 changed components and no Ford warranty. Yet Saleen is more popular.
