At the 2017 World of Wheels show in Rosemont, Illinois, Lou Costabile finds a Lightning Blue Roush Stage 3 Mustang that isn’t owned by a collector at all — it’s a rolling partnership between Roush Performance and Meguiar’s Car Care Products. Driver Spike Anderson explains exactly how that arrangement works and why this six-speed, supercharged Mustang exists in the first place. The story behind the car turns out to be as interesting as the car itself.
