In the Roush Mustang hierarchy, the top dog is the Roush Stage 3 Mustang. It’s the one with the supercharger to go along with all the style and handling mods that Roush has to offer. It’s also the version that carries a massive price at $24,995 over the cost of the base Mustang. For those who want the Roush style, but want to spend about half that much on their car, the 2020 Roush Stage 2 Mustang might be just the ticket. It’s $12,995 on top of the price of the base Mustang, certainly not cheap, but that is $12,000 cheaper than the Stage 3 car. The buyer could always add a supercharger down the road and save some cash.
