31 Years, One Owner: This 1959 Triumph TR3A Rode Through Glacier and YellowstoneThe TR3A arrived in 1957 as Triumph's refinement of the original TR3, adding a wider front grille, exterior door handles, and a lockable trunk to a formula that already included front disc brakes, a genuine rarity on a production car of that era. Power came from a 1,991cc inline-four feeding a four-speed manual gearbox, keeping the TR3A honest as a driver's machine rather than a boulevard cruiser. It went on to become Triumph's best-selling model of the period, with the majority of production heading to the United States.This particular example, listed for sale on Hagerty Marketplace, comes with a genuinely rare backstory: the same family has owned it for 31 years, using it for road trips through Glacier, Yellowstone, and Teton National Parks along with multiple runs over Beartooth Pass. Finished in Primrose Yellow over a tan interior, the car wears paint applied roughly 25 years ago and comes with a color-matched removable hardtop plus a full set of weather equipment, including a soft top, tonneau cover, and side curtains.Mechanically, the car has had attention where it counts: replacement SU carburetors, an overhauled rear differential completed by a British Motor Works specialist in Oregon, refreshed wheel bearings, and a Pertronix electronic ignition conversion. It shows honest wear consistent with three decades of use, including various paint chips and scratches and older-date-code tires, and comes with a clean Oregon title, a tool kit, spare parts, and the original servicing manual.AdvertisementAdvertisementBidding is live now, with the auction closing on Wednesday, July 22.
