1975 Triumph TR6

The TR6 experience is an undiluted visual and aural treat, some would argue it's the last of the great TR's.

Launched as a clever update on the TR5, Triumphs Karmann facelifted TR6 took over as its open-top roadster in 1968. TR6 gained a positive reputation for its strong power-plant, raw driving experience and straightforward DIY. Often lauded as the last true Triumph sports car, it has a loyal following helped by an excellent parts supply and no end of specialists. As an archetypical sports car, with its rasping exhaust note, nicely weighted gear change and snug cabin, the TR6 is the natural evolution of the TR Series and remains as sought after as ever.

The current owner has been the custodian of this car for over 20 years, with just three previous documented owners. This 1975 car has seen restorations, engine rebuilds and repaints over the years, with the current engine set-up offering an impressive mechanical state of tune. With over £8,000 of engine modification invoices to coax out around 30% more power from the straight-six CR series 2.5-litre engine, the performance of the car is very much the highlight. As a genuine UK RHD car, it comes with a stack of paperwork, old MOTs as well as its original service book. It is also fitted with the desirable overdrive option, the cars chassis is solid making it an ideal candidate for a rolling resto.

This auction listing was written from information supplied by Darren Rungasamy after meeting Nick the owner, and having visited and photographed the vehicle.

Meet the owner

I purchased this TR6 back in 2000 and had the engine tuned to assure complete driving satisfaction.

As a former travelling engineer, Nick was using a Volvo estate to visit site locations but decided to seek out something that would make his rounds more interesting. As a signature of arrival, it certainly didn’t get much more memorable than a TR6, and he used the TR6 as his ‘working car’ for around 10 years.

It proved to be comfortable and reliable and even treated to a trip across Europe one year. The car was also converted to run on LPG during this time, which has since been removed due to the reduced availability. In recent years, while mechanically and structurally strong, age has caught up with it and he has (with a little persuasion from his better half) decided to move the car on. He'll be happy to answer any questions you have about the car in the comments section below.

The handsome chiselled styling is arguably the ultimate evolution of the TR cars.

Wheels and Tyres

The steel wheels are straight with no significant kerb damage, but would clearly benefit from a refurb. All of the Goodyear tyres date from 2014 and are in good condition with plenty of tread. These are 195/65R 15 profile tyres, an upgrade on the standard size you'll find on most TR6's.


The overall presentation of the car looks tired and would clearly benefit from restoration but the panels themselves are comparatively good, on our visit we didn't observe any significant dents or scuffs, and the fit on the panels looked ok too.

There are tatty edges at the bottom of each side door but they open and close with minimal fuss, with no evidence of sagging. The front edge of the car, particularly around the front wings will need attention. The main issues are the inner wings, particularly around the front of the rear footwells and sills, along with the bottom of the B posts. The boot well has seen work in the past. The chassis is free from rippling and the engine bay and front footwells are remarkably solid. It's worth bearing in mind that the TR6's parts availability is good, so the car lends itself as an ideal project. The hood is in very good condition, with no damage noted. The plastic glass panels are crack free.


The finish has aged somewhat but the paint job carried out some 20 years ago appears to have been of a decent standard as the colour is evenly applied with no suggestion of poor preparation or overspray. It still maintains a decent lustre and could polish up well, or be left as is if a "rat look" TR is what you're after.

Glass and Trim

The windscreen is good, with no damage. The side windows are good, with the expected signs of age but are crack free. The passenger door winding mechanism would benefit from some attention. The chrome is a mixed bag, with the rear bumper and off-side headlamp bezel being the main offenders, but the rest of the fittings being well above salvageable. The rubber seals are in good condition, there was no evidence of water in the boot or cabin.


Unexpectedly spacious and practical, with some touches of luxury.

Seats and Carpets

The car has been installed with Mazda MX5 seats, a typical upgrade for those who enjoy touring, acting as a comfortable alternative and the seats are in good condition. Both seats have no significant issues in regards to wear. The door cards themselves are in good condition but will need attention to their fixings to the door. The carpets were likely to have been replaced during a previous restoration and could clean up well.


The dashboard unit is good, with no cracks noted on the top of the facia. The vinyl is a little worn on the centre console with loose fittings, with the switches and dials reflecting the age of the car. The veneer on the facia will need replacing, the dials are complete and functional, if a little worn. An aftermarket DAB/MP3 player with rear speakers has been installed.

Steering Wheel / Gear Stick

The Mota-Lita steering wheel has been retrofitted and the leather is in decent condition, with light corrosion noted on the metal components. The gear stick metal is also rusty, with the knob aligning to the age of the car.


The engine is the car's secret; it has undergone some remarkable improvements.

Engine and Gearbox

Mechanically the car has seen extensive engine work, with Webcon injection, road race cam, lightened flywheel, a modified big end bearing all of which offer a far more powerful state of tune than a standard TR6. Nick informs us that it's said to produce around 185BHP.

With over £8,000 spent in the early 2000s on the engine, the car still has an urge to it and sounds magnificent. It starts up with no issues, with very little in terms of excess exhaust smoke and no oil drips were observed but it does look like some of the hoses for the fuelling will need attention as there was visible drips. No knocking, clonking or grinding was heard from the engine. The gearbox has overdrive and the gears are said to shift smoothly, the clutch was also uprated to cope with the extra power and Nick mentions it functions without issue.

Suspension and Brakes

The brakes were not ignored either when the engine work was completed, as a 4 pot caliper kit was fitted to ensure it stopped as well as it went. All are in decent condition, although the pipes may need attention. The suspension components have also seen attention over the years, although the shock absorbers will need to be checked. The rear trailing arms mounts look ok. No squeals were noted on the brake operation.

The Drive

Lending itself as a bit of a sleeper, this TR6 has been well tried and tested over the years and its reliability has never really been in question. Because the car has seen relative inactivity and has been stored off-road but out in the open, it will need fettling but it's said to drive well. The car retains its excellent handling characteristics and that patina does have a certain attraction. The car has been fitted with a roll bar, which goes some way into helping its structural rigidity, with no obvious signs of creaking noted.

Electrics and Other

The engine electrics are in good order with no significant issues, with the lack of use though it is recommended that they are checked.

History and Paperwork

Expertly tuned, this sleeper with a good history has huge potential, and is priced with a very competitive reserve for sale.

The car retains its original BL Service booklet, which documents evidence of its earlier servicing records. The car saw a full body restoration in 1986, mostly to remove the rust that comes with age. Nick took the car on in 2000, and it was subjected to a series of significant engine modifications carried out by a local firm. This included a second engine rebuild with the bores, head and crankshaft all machined, race cam, lightened flywheel along with an uprated clutch, with the further addition of a modified inlet manifold, Webcom Fuel Injection kit, uprated drive shafts and a new exhaust.

The car also received new paint not long after Nick took ownership. Other items, such as a new hood, suspension components, weatherstripping, a leather Moto-Lita steering were added fairly recently, and dozens of invoices from specialists suggesting regular mechanical attention.
