Interior and Controls

The cockpit pairs low‑back buckets in black leather with racing harnesses and a wood‑rimmed steering wheel. Smiths gauges, a Lucas ammeter, and a dash‑mounted rearview mirror reinforce the period‑correct look. A heater adds usability for cool‑weather drives while keeping the cabin simple and focused.

Powertrain and Performance

Power comes from a Roush Performance 427SR V8 fed by a Holley carburetor and polished Edelbrock intake, sparked by MSD ignition and breathing through tubular headers to side-exit exhausts. A Tremec TKO600 five-speed manual sends power to the rear wheels. Recent service in July 2025 included an oil change, new spark plugs, and fresh transmission and differential fluids.

The sale closed at $92,000 in a no-reserve online auction on August 22, 2025, reflecting strong interest in clean, analog V8 cars with authentic driver-focused specs.

Highlights

Built by Superformance under license from Carroll Shelby Licensing Inc., MKIII chassis feature hand‑laid fiberglass bodies, TIG‑welded ladder frames with crumple zones, and authentic cockpit details. This example rides on 15‑inch Halibrand‑style wheels with knockoffs and Cooper Cobra Radial G/T tires.

Exterior and Chassis

The fiberglass body features a single roll hoop, hood scoop, Talbot Berlin‑style side mirror, fender vents, quick‑jack bumperettes, and a LeMans‑style fuel filler. Paint‑protection film covers the front end and rocker panels. Four‑wheel disc brakes and independent suspension help the MKIII deliver period-correct feel with modern control.
