About this car

The GT6 is Triumph's fastback take on the Spitfire, with a 2.0-litre straight-six in place of the four-cylinder. This 1974 Mk3 is a right-hand-drive home-market car with overdrive, first registered in Berkshire in March 1974. A British Motor Museum Heritage Certificate confirms it was built in August 1973 in Mimosa Yellow with black cord trim. The dealer believes the current yellow is the original shade, and the car sits on black Minilite-style wheels.

It shows 45,937 miles, and the MOT history on file runs back to 2009 with a steady, low annual mileage. It is reported to have been restored within the last ten years, including a repaint, engine and gearbox rebuilds and a carburettor and fuel system rebuild. The earlier history file has been lost, so that work is not documented. It has had ten former keepers.

Malton Coachworks carried out recommissioning in April and May 2026, costing nearly £10,000. This covered a carburettor rebuild, brake service, new shock absorbers and driveshaft bushes, and a new fuel lift pump and speedometer cable. New chrome bumpers are due to be fitted before delivery. It comes with the V5C, Heritage Certificate, owner's manual, recent invoices and MOT certificates. It is MOT and road tax exempt.
