Selling my ROUSH RS3 Hyper number 15 of 25. Came stock from the ROUSH factory with 540 HP. I've upgraded it with the Phase II upgrade kit (from ROUSH) boosting the power to 625 HP and 525ft-lbs torque as advertised by ROUSH. One of the best mustangs I've owned and I doubt anyone would be disappointed driving this machine. I also darkened up the windows a bit with a professionally installed window tint on the rear, side quarter, driver, and passenger windows. Meticulously taken care of and always taken in for scheduled maintenance. Driven typically as a funday driver. Eye catching ride that gets continuous compliments and I can't overstate the amazing exhaust note and power. ROUSH definitely knows what they're doing and you'll be very pleased driving this vehicle.
