Starting up front, Kenny Davis Hot Rods in Rogers, Arkansas, modified the grille shell and lower valance that were filled with custom mesh. The factory foglights were removed and the openings are now used for intake ducts. New foglight slots were cut and lights installed in the bumper. All of the original plastic GT ground effects were removed and molded out of fiberglass for added stiffness, while a fiberglass cowl-induction hood was installed with hoodpins and scuff plates. Under that trick hood, custom inner fenders were made to allow full turning radius. Helping clean up the body lines, the door handles, door locks, tailgate handle, and gas filler door were shaved smooth. In the bed, wheel tubs and a bridge were made out of sheetmetal, and a custom enclosure was built to house the batteries and subwoofer. Kenny Davis Hot Rods could now roll the truck into the spray booth. The top half was covered in 2008 Mitsubishi Spyder Eclipse Sunset pearlescent and the bottom half in '04 Porsche Prosecco metallic. Subaru black granite. was added to the hood for a standout look. Before the truck was cleared, Martin had the name of the truck, Twin-Turbo Syborg, and the engine size, 4.7L, airbrushed on the bottom of the doors. On the home stretch, the last thing for Syborg was a new interior.

The core of the interior is the handbuilt dash by Competition Fabrication. This houses the Auto Meter Sport Comp gauges, Kenwood head unit, and Vintage A/C controls. The one-off door panels were also built by Competition Fabrication, then the whole interior was covered in light brown leather by Recovery Room Interiors in Plattsmouth, Nebraska. Something we have never seen before is the headrests removed from the seatbacks and remotely mounted to the rollbar. Pretty darn trick fellas. Speaking of the rollbar, 1¾-inch chromoly tubing is welded directly into the frame providing both added safety and strengthening the chassis. To finish off the interior, a matching Billet Specialties steering wheel, wrapped in the same leather as the rest of the cab, was installed. The Kenwood head unit feeds the audio to two Kicker amplifiers that in turn supply sound to two Kicker 10-inch subwoofers, and two sets of Kicker 6½-inch speakers in the doors for plenty of high-quality tunes while Martin is burning rubber.

We can say without a doubt that Martin's Sonoma GT is the baddest one we have ever seen. It was a long, eight-year process, but in the end, Martin accomplished his goal of building one amazing Sonoma. He wanted to say thank you to all of the companies that aided in the build as well as all of the shops that worked on it. Now all that is left to do is get out to a track and smoke the tires. Camaro, Mustang, and Challenger owners, you've been warned.
