Buyer’s notes
About the Triumph GT6 Mk1
The GT6, launched at the 1966 Paris Salon, was a fastback coupé on Spitfire lines with a 2.0-litre six. The Mk1 kept the Spitfire’s swing-axle rear suspension, which road testers criticised; the Mk2 replaced it in 1968.
What moves the price
- Chassis condition: the separate chassis gives the car its strength, and rot in it is costly.
- Originality: the correct engine and specification for a Mk1.
- Body condition, including the one-piece bonnet.
Before you buy, check
- The chassis outriggers, the rails around the differential and front suspension mountings, and where the front rails meet the bulkhead.
- The bulkhead, sills, floors, battery box, door bottoms and the bonnet.
- The engine number: the correct engine’s code begins with K.
