Roush package was only offered in 2000 and 2001 by special order. They didn't sell many because people viewed the Expy as a family vehicle and no more. Although this one handles quite well with it sitting so low and the Roush suspension upgrade. There were only 112 made so they are rare. They were only offered in Stage 1 which means it is all exterior mods by Roush, the gray bumper package, the Roush exhaust system, 2x4 Touring suspension, ceramic coated headers, the Roush chrome racing wheels, and all the Roush badges, decals and emblems. I live near the dealership where it was purchased, i am the second owner. There is very little info out there about these but i don't believe, although it woulda made it a beast, that the supercharger was offered because that is only available in a Stage 3 Roush modification. It has the Triton 5.4 V8 with a Roush Air intake which gives it tons of power.
