Roush offers a dealer locator tool on its website, RoushPerformance.com, that allows customers to locate dealers selling Mustang GT cars tuned by the aftermarket performance tuning company. Most of the dealers are Ford dealers partnered with Roush in a network throughout the United States, but some other dealers sell the cars as well. Finding a dealership for the car is likely in most major metropolitan areas.
In the Los Angeles area as of 2015, Ken Grody Ford in Buena Park and Galpin Ford in North Hills sell Roush-tuned GT Mustangs. The company also sells cars in Australia, Canada and the United Arab Emirates through its dealer partners.
Roush Performance tunes a variety of cars, but is best known for its Ford Mustang tuning programs and aftermarket parts catalogs. The company has an official partnership with Ford to sell tuned Mustang cars that come with a warranty, offering performance ranging from slightly higher than stock to cars that are designed for drag use at the track.
As of the 2016 model year, Roush offers tuned Mustang GT models in Stage 1, Stage 2 and Stage 3 programs, as well as its own high-output RS Mustang. The company also offers tuned F-150 Raptor Ford trucks. Online and print parts catalogs allow Mustang owners to order individual components for their own cars even if they were not purchased through a Roush dealer, with systems ranging from exhaust to engine tuning programs to aftermarket aerodynamic kits.
