This 2005 Ford Mustang GT, known as the "Black Rose Concept," represents a distinctive take on the debut year of Ford's fifth-generation "S-197" platform. According to the seller, the car was modified by Bonspeed of Anaheim, California, combining substantial performance upgrades with bespoke styling. The 2005 model year marked the return of retro-inspired Mustang design that channeled the iconic 1960s originals, and the GT variant delivered 300 horsepower from its 4.6-liter V8 in factory form—making it a significant milestone in the nameplate's history.

Key characteristics include:

• Powertrain: A 4.6-liter V8 enhanced with a Vortech V-2 centrifugal supercharger and Maxflow Power Cooler aftercooler system, delivering power through a five-speed manual transmission
• Wheels & Brakes: Polished 20-inch Bonspeed wheels with staggered Hankook Ventus V12 evo2 tires (255/35 front, 285/30 rear), plus Baer front brake calipers and two-piece cross-drilled and slotted rotors at all four corners
• Exterior: Black finish with custom body panels, hand-painted pinstriping, Black Pearl hood graphics, hood pins, rear spoiler, fog lights, and dual exhaust outlets
• Interior: Power-adjustable Recaro front seats trimmed in red leather with matching red accents throughout the cabin, a Hurst shift knob, and a Kenwood head unit paired with a Sony rear-seat entertainment screen
• Audio: A trunk-mounted custom enclosure featuring an Optima battery, Diamond Audio Technology amplifier, four crossovers, and a 5-farad Tsunami capacitor

Described as Modified in originality, this coupe reflects extensive aftermarket enhancements across its drivetrain, suspension, brakes, bodywork, and interior. The odometer is said to show approximately 3,700 miles, though the total mileage history is not fully documented.
