This 2024 Ford Mustang GT Premium fastback was purchased new by the seller at Havre Ford of Montana in 2023, and the 5.0-liter Coyote V8 was subsequently modified with a Whipple Gen 6 Stage II 3.0-liter supercharger, upgraded oil pump and pulleys, and Kooks 1 7/8” long-tube headers with a Steeda H-pipe and high-output catalytic converters. The engine is linked with a six-speed manual transmission, McLeod RXT HD twin-disc clutch, a limited-slip differential, and GT350 rear axles. Finished in Dark Matter Gray Metallic over Black Onyx leather, the car is further modified with a Liquivinyl front splitter, an RTR front grille, rear window louvers, Steeda lowering springs and adjustable toe links, an MGW short-throw shifter, a VIOFO front and rear dash cam system, and two 12″ Kicker Comp R Subwoofers. This modified S650 GT Premium has 6k miles and is now offered with a window sticker, the owner’s manual, removed and spare parts, and a clean Montana title in the seller’s name.

The car is finished in Dark Matter Gray Metallic (HY) with matte black stripes, and exterior equipment includes a Liquivinyl front splitter, an RTR front grille, LED headlights, a rear spoiler, hood vents, rear parking sensors, Bronze Package badges, side window louvers, smoked taillights, and sequential LED taillights. There are scratches on the left rear quarter panel and front bumper.

The 19″ Y-spoke alloy wheels are mounted with ProContact RX tires. The car has been modified with Steeda lowering springs and adjustable toe links as well as GT350 rear axles. Stopping power is provided by six-piston front and four-piston rear Brembo brake calipers.

The heated and ventilated front seats are upholstered in Black Onyx leather, which extends to the door panels. Amenities include an MGW short-throw shifter, a VIOFO front and rear dash cam system, a power-adjustable driver’s seat, a 12-speaker Bang & Olufsen sound system, a wireless charging pad, a rear view camera, a navigation system, cruise control, dual-zone automatic climate control, Co-Pilot360, and SYNC 4 infotainment with a touchscreen angled toward the driver. Two 12″ Kicker Comp R Subwoofers are installed in the back and are controlled by a knob located in the glovebox.

The leather-wrapped flat-bottom steering wheel fronts a configurable 12.4″ digital instrument cluster that includes readouts for speed, engine RPM, and ancillary data. The instrumentation and infotainment screen wear a matte protective cover. The digital odometer indicates 6k miles, all of which were added under current ownership.

The 5.0-liter Coyote V8 was modified with a Whipple Gen 6 Stage II 3.0-liter supercharger, intercooler, and open air box system. A revised crank sprocket, oil pump gears, and upgraded pulleys were also installed along with Kooks 1 7/8” long-tube headers with high-output catalytic converters and a Steeda H-pipe. An oil change was most recently performed in August 2026.

Power is routed to the rear wheels through a six-speed manual transmission, McLeod RXT HD twin-disc clutch, and a limited-slip differential. The car is equipped with optional active mufflers.

The Carfax report is free of accident or damage entries and lists open recalls.

There is currently a lien on the car, and the seller’s lender will need to be paid off before the title can be transferred to the new owner.
