This 1973 Triumph TR6 was purchased new in November 1973 by a resident of Greenville, South Carolina. The seller bought the car in 2006 and subsequently conducted a multi-year refurbishment that began in 2016 and cost approximately $80k. The 2.5-liter inline-six was rebuilt in early 2026 and is augmented by triple SU carburetors, and the four-speed manual transmission was resealed during the same time period; the gearbox is complemented by an overdrive unit. The vehicle has been repainted in French Blue, and the interior has been retrimmed in black vinyl. Good Parts supplied the GP3 camshaft, the CV-jointed rear axle and hub assembly, and a number of other components referenced below. Additional equipment includes a black convertible top, a body-color removable hardtop, a tonneau cover, and a top boot as well as Weller 15″ steel wheels, Coker red-line tires, power-assisted front disc brakes and rear drums, a luggage rack, an Advance Auto Wire PowerBlock kit, a BVU vacuum system, an aluminum radiator, an exhaust header, and a stainless-steel exhaust system. This TR6 is now offered with a British Motor Industry Heritage Trust certificate, service records, a hardtop stand, a car cover, and a South Carolina title in the seller’s name.
The 2.5-liter inline-six has been modified with a Good Parts triple-SU-carburetor setup, which includes the intake manifolds and airbox.
The engine was rebuilt in 2025 by Custom Classics of Lexington, South Carolina; the block was machined for cam bearings, and the cylinders were honed. The straight-six is complemented by the following equipment:
- Machined crankshaft
- Good Parts GP3 camshaft
- Finned-aluminum valve cover w/Triumph-crest nuts
- US Radiator aluminum radiator
- Good Parts “TR6”-engraved aluminum radiator shroud
- Good Parts oil-galley plugs
- Good Parts in-line bored camshaft journals
- Good Parts camshaft bearings
- Good Parts carburetor-accelerator-shaft bushing kit
- British Vacuum Unit remapped distributor
- British Vacuum Unit vacuum-advance module
- Advance Auto Wire PowerBlock wiring kit
- Gear-reduction starter
- Good Parts Jet-Hot-coated exhaust header
- Tourist Trophy stainless-steel exhaust system
Parts that have been replaced since 2022 include the rod bearings, main bearings, seals, thrust washers, piston rings, head studs, crankshaft-damper pulley, ignition coil, condenser, points, alternator, and water pump. The seller states that the engine can be finicky to start due to the ignition-timing setup.
A seller-provided list of work performed since 2022 is provided above.
The car was finished from the factory in French Blue (126). The body had sustained damage in an accident decades before the seller purchased it and rust had developed, so sheetmetal for both quarter panels, the rear valance, and the B-posts behind the doors were replaced during the refurbishment—in the 2016–2021 time frame—before the vehicle was repainted in French Blue. The replacement black convertible top has reflective striping. The stainless-steel bumpers, grille, windshield, weatherstripping, and taillight lenses were replaced during the refurbishment. The seller notes a couple of flaws and dings on the body.
The seller purchased a used hardtop and had it repainted to match the car. Black “TRIUMPH” stripes adorn the rocker panels. Other features include a plastic black air dam, a driver-side mirror, a black top boot, a flip-up fuel cap, a black finish on the rocker panels, Union Jack quarter-panel decals, a luggage rack, a black tail panel, and dual exhaust outlets.
Silver-painted 15″ steel wheels from Weller Wheels feature polished trim rings and are mounted with Coker Classic red-line tires measuring 185R15. The suspension was overhauled in 2010. The steering rack was replaced in the early 2020s, as were the ball joints, the brake master cylinder, and the front brake rotors and pads.
The bucket seats were rebuilt and retrimmed in black vinyl in 2009, and the trim panels were replaced. A HushMat noise-reduction kit was applied before the carpeting was redone. Interior appointments include a center console, a wood dashboard, a heater, seatbelts, door-panel pockets, and bright doorsill plates. The seller notes that the British Leyland AM/FM radio powers on, but speakers are not installed. The ignition switch has been relocated to the center stack.
The three-spoke steering wheel fronts a 140-mph speedometer and a 7k-rpm tachometer, while gauges for coolant temperature, oil pressure, fuel level, and voltage are positioned at the center of the dashboard. The five-digit odometer shows 3k miles; approximately 17k miles have been driven under current ownership, and true mileage is unknown. LED bulbs have been installed for the gauge lighting. The temperature-gauge wiring has been updated to use a voltage stabilizer.
Power is routed to the rear wheels through a four-speed manual transmission with a J-Type overdrive, for which the seals were replaced in early 2026. The clutch system was replaced in 2025, and a Good Parts roller-bearing clutch mechanism was adapted. A Good Parts rear axle and hub assembly utilizes CV joints instead of universal joints. Nylatron differential bushings are installed.
The replacement identification plaque is shown above.
The British Motor Industry Heritage Trust certificate indicates that the vehicle was built on August 21, 1973, and lists the factory serial numbers, colors, and equipment along with initial delivery to Jacksonville, Florida.
The South Carolina title notes “Exempt” under the Vehicle Brand(s) section.
