The 425ci Nailhead V8 used in Gran Sport examples featured dual four-barrel carburetors, hydraulic lifters, and a 10.25:1 compression ratio. An aluminum radiator was fitted along with a five-blade fan.

Power is sent to the rear wheels through a three-speed Super Turbine automatic transmission that was rebuilt in 2014 along with a Positraction rear axle with 3.42:1 gears. A replacement dual exhaust system has been installed.

A window sticker, a Protect-O-Plate, manufacturer’s literature, initial purchase documents, and service manuals are included in the sale.

The two rows of bucket seats are trimmed in button-tufted black vinyl upholstery. Wood veneer accents the center console and door panels, and additional details include a power-adjustable driver seat, a remote-controlled mirror, a Sonomatic radio, a rear speaker, and power side windows.

The two-spoke steering wheel frames a 140-mph speedometer, an analog clock, a fuel-level gauge, and warning lights for oil pressure, coolant temperature, and amperage.

The five-digit odometer shows 41k miles.
