The GT6 was Triumph's small fastback coupe with a six-cylinder engine, effectively a Spitfire chassis with a 2.0-litre straight-six and a Stag-style rear end of ambition. This 1971 car is a left-hand-drive import from the US, finished in Triumph Signal Red.
It has been restored to a high standard, with much of the work done by T R Bitz. The cabin has been reworked rather than returned to factory spec: custom black leather seats built on the original frames, modified for more front support, with cup holders and USB sockets, plus an alcantara headlining.
Mechanical and other upgrades include electronic ignition, K&N air filters, a stainless exhaust, a hi-torque starter, Minilite wheels and LED headlights. The page lists 3,726 miles (5,996 km) on the odometer and an MOT to April 2025. It has recently made a trip to Santorini without problems.
