IF YOU want some real muscle under your right foot Mustang Motorsport is selling its Roush-fettled Mustang launch cars, used to announce their partnership with the famed American tuning firm.

The Roush 'Stangs were a star attraction at the recent Phillip Island Historic meeting before being let loose at a recent track day at Sandown Park in Victoria.

Up for grabs is a 2017 Ruby Red RS3 Roush Mustang, with 670 horsepower and auto gearbox that has travelled just 2400kms. It’s a serialised Jack Roush Signature car, the same as you can buy in the USA and comes with all authenticity documentation – it is compliance-plated as a Roush Mustang.

The second 2017 RS3 Roush is finished in QuickSilver and has just 2700kms on the clock. It has 727, that’s right, 727 horsepower to play with and it also has Roush authenticity documents and Roush compliance.

“These two Roush RS3s are currently the only right-hand drive versions in the world and are simply breathtaking to drive,” says Mustang Motorsport's Craig Dean. "Of course if you already own a Mustang and want to give it some real horsepower, we can transform it into a Roushcompliant fire breather in two weeks," he added.
