While at the Frankfurt show in Germany I saw a Roush Mustang tooling around in the parking lot. After a visual diet of only small, diesel-powered economy cars, the sight of an American muscle car in Europe was strange. That's about to change as Roush is introducing the Limited Edition Model 420RE in Europe his month. The company has been operating in Europe for 10 years this month, though the 420RE marks its first retail offering. The Stang will be marketed by American Carriage Company in London and set some lucky Europeans back £39,950 or around $71,000US.
