Vehicle Details
AI Listing Summary
This 1973 Triumph GT6, sold for £8,800, features a recent full respray and significant re-commissioning work by a specialist. It includes desirable upgrades like a Webasto sunroof, electronic ignition, and working overdrive, making it an attractive proposition for enthusiasts.
Condition
7
The car has had a full respray in 2017 and has been garaged since. It recently underwent £1,200 of re-commissioning work by a Triumph specialist, including rear brakes, carbs, and a general service. The vendor has owned it for 18 years, and it has a refurbished Webasto sunroof. While it has period Minilites, electronic ignition, and working overdrive, the description does not explicitly state the absence of minor cosmetic flaws or the need for any reconditioning beyond the recent specialist work. Therefore, 'Very Good' seems appropriate.
