This 1971 Triumph GT6 Mk III is finished in green and powered by a 2.0L inline-six equipped with dual Zenith-Stromberg carburetors. The car rides on body-color 13″ vented steel wheels and is further equipped with a Mountney steering wheel, a wood dashboard, and a four-speed manual transmission. It was acquired by the seller in 2026 and subsequently fitted with TR6-style tan seat upholstery as well as a replacement headliner and carpets. Additional work in preparation for the sale involved changing the cylinder head gasket, performing fluid changes, and undercoating the underbody. This GT6 Mk III is now offered with partial records, spare parts, and a clean Ohio title in the seller’s name.
The GT6 Mk III had revised styling including a restyled nose and tail, rubber mud flaps fitted inside the front fenders, a more upright windshield position allowing more headroom, a wider chrome finishing strip around windshield, a relocated gas filler in the left-rear fender, and lengthened air vents above the rear fenders. This example left the factory finished in Signal Red (32) and was repainted green under previous ownership.
The body-color 13″ vented steel wheels wear bright center caps and trim rings. They are mounted with a mixed set of 155/80 Goodyear front and 185/60 Michelin rear tires. The car is further equipped with rack-and-pinion steering as well as front disc brakes paired with rear drums.
The cockpit features bucket seats that wear TR6-style tan upholstery with black piping, and matching trim extends to the center console and door panels as well as the rear of the cabin. The seller notes that the seat upholstery was installed under their ownership along with a replacement headliner and carpets.
The wood-rimmed Mountney steering wheel fronts a wood dashboard housing Smiths instrumentation consisting of a 140-mph speedometer, a tachometer with a 6k-rpm redline, and gauges for fuel level and coolant temperature. The five-digit odometer shows 59k miles, approximately 400 of which were added under current ownership.
The 2.0L inline-six was equipped from the factory with dual Zenith-Stromberg carburetors and factory rated at 104 horsepower and 108 lb-ft of torque. The engine was reportedly rebuilt under previous ownership, and work following the seller’s acquisition is noted to have involved replacing the cylinder head gasket as well as performing an oil change.
Power is sent to the rear wheels through a four-speed manual transmission. The seller notes that the transmission and differential fluids were changed, the chassis was lubricated, and a protective coating was applied to the underbody during their ownership.
