1973 Triumph GT6 MK3

Highlights

  • Over £4,000 recently spent with Triumph specialists 
  • Last year of production GT6, benefitting from updated rear suspension design 
  • Historic restoration remains in excellent shape 
  • Well-maintained example, dry stored and driven on salt-free roads in dry summer months

The Appeal

Closely related to Triumph's Spitfire roadster, the GT6 was produced from 1966 to 1973. Early development saw that prototype car starting from a standard 1963 production Spitfire, modified to include a fastback top as opposed to the convertible which was currently in production. The updated styling and design were well-received; however, due to the added weight introduced with the hard top, the standard Spitfire’s 4-cylinder engine did not provide enough power and the prototyping and development of the hard top were put on hold. 
During the 1964 Le Mans season, the prototype’s fastback design was introduced to Triumph’s racing Spitfire, producing a marked upgrade to the vehicle’s aerodynamics, and providing a 1st place finish in their class at Le Mans in 1965. Based on the success and popularity of the winning Spitfire with hardtop, the fastback production vehicle was revived, and eventually came in the form of the GT6. Powered with Triumph's 1,996 cc straight-six to overcome the extra weight from the fastback, the vehicle was released in 1966, a year later. This GT6 in particular benefits from a historic bare metal respray and restoration, performed sometime before 1992, as is confirmed by a historic valuation certificate as well as the current condition of the car. 
This car has had every detail highlighted in the recommissioning report addressed and is ready to be enjoyed, wanting for nothing mechanically and electrically. With the vehicle remaining in great condition from the restoration, and in the desirable bright red colourway, this is not one to overlook. Additionally, being a late model Mk.3 GT6, this one benefits from redesigned rear suspension, which many consider to be the most desirable configuration for these cars.
