About the GT6 Mk3

The Triumph GT6 Mk3 (1970-1973) had restyled tail (as Spitfire MkIV), 104hp. Around 13,000 built. Final GT6. Values from £16k.

Known Issues to Watch For

GT6: Engine: 2.0 straight-six from Vitesse/2000 - smooth, lovely sound. Timing chain, oil leaks, water pump. Carburettors: Twin Strombergs need setup. Gearbox: 4-speed, overdrive essential. Rear suspension: Mk1 swing-axle is DANGEROUS - more power than Spitfire makes it worse. Mk2+ has lower wishbone - much safer but still tricky. Chassis: Backbone as Spitfire but strengthened. Check thoroughly. Body: Steel fastback - same rust areas as Spitfire plus rear hatch seal/surround. Overheating: Can run hot - check cooling. Values: Rising - attractive usable classic. Mk2 best balance. Budget £2-3k annually.
