At first glance, the GT-100 looks like a familiar modern muscle car. The front end reads unmistakably Mustang, complete with the aggressive face of a 2007 Mustang GT. That illusion doesn’t last long. A few steps to the side, and the car’s identity collapses into something far stranger: a pickup bed, vintage truck proportions, and a silhouette that refuses to fit neatly into any category.
The GT-100 is the result of a full steel custom build that combines a 2007 Ford Mustang GT with a 1955 Ford F-100 pickup. While many restomods rely heavily on fiberglass or carbon fiber, this project went in the opposite direction, committing entirely to steel construction. That choice alone sets it apart in a space often driven by lightweight materials and modern shortcuts.
Under the hood sits the Mustang’s 4.6-liter V8, producing 300 horsepower and sending power to the rear wheels through a five-speed manual transmission. That drivetrain choice pushes the GT-100 firmly toward muscle car territory, especially when compared to the original F-100’s period-correct Y-block V8. Mechanically, it behaves far more like a Mustang than any truck it resembles.
The build process favored modern architecture over nostalgia. The Mustang donor car was stripped of its bodywork but kept its underlying structure, abandoning the ladder-frame chassis typical of a 1950s pickup. Onto that platform went the doors, roof, bed frame, and greenhouse from a Ford F-100, blended with custom front-end panels designed to preserve the Mustang look.
Visually, the contradictions multiply. Oversized fender extensions stretch the body to lane-filling width. A fixed rear wing rises from the tailgate, while side intakes and a windshield cover blur the line between race car and show truck. Shelby Blue paint with white stripes reinforces the Mustang identity, even as the pickup bed tells a completely different story.
Inside, the confusion continues. The cabin remains pure Mustang, with recognizable gauges, steering wheel, and dashboard untouched by the truck transformation. It is a pickup you sit in like a pony car, which may be the most unsettling detail of all.
The GT-100 recently sold at auction, finding a new owner willing to embrace its contradictions. Love it or hate it, the vehicle exposes a growing tension in custom car culture: when builders refuse to respect traditional categories, the result may look wrong—but it can still be impossible to ignore.
