1972 Triumph GT6 MK3 GT6 MK3

1972 Triumph GT6 mk3 2.0L i6, 4sp, 35k miles Clean Minnesota title in-hand

Originally sold new in St. Paul - we found this car in a barn in 1999, and it has been in my family since then. My younger brother owned it between 1999 and 2010, doing all of the original work to get it back on the road. I bought the car from my brother in 2010, doing the next round of restoration work. Most replacement parts are either NOS, reproduction correct, or upgrade from factory spec. Lots of spare parts included. I'll miss this car, but, it's time for a new project.

These are relatively rare with about 40,000 GT6s sold worldwide between 1966 and 1973. Only 13,000 mk3 cars were built between 1970 and 1973, with around 5,000 coming to the US. If you've been following the market on these - you know it has gotten quite a bit stronger in the last couple of years, roughly doubling since 2014.

Please ask all questions prior to bidding. I have included 82 high-res photos (click for full-size of any of them), as well as some running and driving footage. Unlike most of the GT6s that have come up for sale in the last couple of years - I've detailed all of the work that has been done to the car. This car is by no means perfect. But it could be the perfect car for someone that wants a presentable driver, or as a restoration candidate.

I will entertain offline offers, and the car is for sale locally. If you are serious about the car, please contact me. I will require a $500 deposit via paypal or certified check within 48 hours of auction close. Final payment can be made via paypal, cash in person, or certified check. The car will not be released for shipping or pickup until funds have cleared. Shipping arrangements and costs are the responsibility of the purchaser. I would recommend closed transport by a company like Horseless Carriage. All of the included parts should fit in the car without a problem. Please ask all questions prior to bidding.

This car has been driven approximately 4,000 miles since 2000; about 700 since the major engine work in 2013. The odometer stopped working shortly after we bought the car, but the speedometer and trip meter still work. This has always been a strong-running car. I have always run non-oxygenated gas with lead additive, and correct conventional oil with ZDDP additive. It wears an older, lower-quality respray from before we bought the car. It's been wet-sanded and buffed, and looks presentable, but if you're picky about looks, or want a show car - you'll want to factor in some paint work. There is some light rust here and there, a few bubbles on the front passenger wheel arch, a bit starting around a couple side-markers, and some surface rust underneath the car. I wouldn't consider any of it to be abnormal for a car of its age.

The car is sitting on period-correct American Racing cast wheels - either aluminum or magnesium. The glass is all original, and in pretty good shape. No heavy pitting sand marks chips etc. The glazing could all be replaced if the car is going to see rain. The chrome is there - but the bumpers are lightly pitted, and the rear bumper has some heavy scratches.

The interior is in decent condition, but the carpet set is showing its age, and could stand to be replaced. The trunk wood is sagging and could be replaced. The rear wings have lost their clips but could be replaced. The headliner has normal stains for a GT6 of this era, but overall is pretty clean. The visors are OK - the foam should be replaced. The rear-view mirror is OK - the internal dimming mechanism mostly works. Headlights (highlow), turn signals, wipers, heat, blower - all work.

In addition to these items, the car may also need:

  • Suspension gone through (rubber bushings, check springsshocks, etc)
  • Rotoflex donuts (donuts included)
  • Tires (equipped tires are weather-checked)
  • Hazards four-way flashers do not work, not diagnosed, new switch included
  • Horn does not work, not diagnosed
  • Reverse lights may not work - may just need bulbs, or wires cleaned up - not diagnosed
  • Dash assembly work - heater tubes, parcel shelf installed, etc - parts included
  • Doors, boot, fuel cap need to be re-keyed. The original keys were lost before I bought the car.
  • Fuel gauge is intermittent - may need a new sender or gauge - not diagnosed
  • The transmission in the car is not original - however the original is included, and is 75% rebuilt. Included with the original is an impossible-to-find NOS laygear. These go for $600-800 when and if they are ever found.

Like anyone that has owned a Triumph for this many years - I am included a bunch of spare replacement parts. Not everything is listed here: Rotoflex donuts, spin-on oil adapter, sealed headlights, carb adjustment tool, original points ignition set, original crank-driven fan, two workshop manuals, newer interior door cards (brown), chrome bullet mirrors, center arm-rest (needs recovering), radiodash support (needs recovering), and a bunch of other items. All-told, there's probably another $1,500-2,000 worth of parts included with the car.
