A long-term owned and extensively improved example of the Triumph TR6, this 1975 car has remained with the same owner for an impressive 48 years. Showing a believed genuine 45,089 miles, the accompanying MOT history provides strong support for this figure, culminating in a current MOT valid until May 2027 with no advisories.
The Vendor reports expenditure of approximately £25,000 during their ownership, including around £17,000 spent with renowned Triumph specialists RevingtonTR in 2014. Although detailed invoices for this major programme of work are no longer available following changes to RevingtonTR’s record system, supporting documentation confirms the fitment of an uprated road suspension package, gearbox improvements and a number of additional mechanical upgrades. Further work has been carried out by classic car specialists Marque21, while a separate programme of bodywork and repainting was completed by another specialist in 2015. Reportedly never driven in wet weather since its restoration, this is a cherished and extensively improved TR6 that has clearly benefited from enthusiastic long-term ownership and considerable investment.
The Vendor advises that the most significant programme of mechanical improvement was undertaken by RevingtonTR in 2014, with expenditure of approximately £17,000. The work reportedly included a reconditioned gearbox, a complete RevingtonTR uprated road suspension package, a new Bosch fuel pump and numerous additional improvements.
Supporting documentation from RevingtonTR confirms many of these upgrades, while further invoices accumulated over the past two decades demonstrate an ongoing commitment to maintaining and improving the car. Invoices from Marque21, experienced classic car specialists, record the refurbishment and refitting of the front brake calipers, together with the manufacture and installation of two new front brake pipes at a cost of £816 in 2014. Further documented work includes welding repairs carried out following a failed MOT, along with the fitment of rechromed original bumpers, new seat belts, a replacement fuse box, condenser, ignition coil and HT leads at a cost of £1,042 in 2013. Additional Marque21 invoices cover a replacement metering unit costing £763 in 2012 and significant mechanical work involving the brakes, clutch hydraulics and steering rack, invoiced at £2,019 during the same year. Further invoices show the replacement of injector pipes, fitment of a new brake master cylinder, replacement fuel-pump components and repairs to a damaged front anti-roll bar mounting.
A separate programme of bodywork was completed by another specialist in 2015. This included repairs to both front wings, the lower nearside door skin, both rear wings and the upper seams, together with replacement headlamps, new door cards and repainting at a cost of £1,034. A professional respray was also completed in 2015, after the earlier Marque21 and RevingtonTR valuation reports had been prepared. Separate RevingtonTR invoices cover the supply of left- and right-hand door panels, boot trim boards, boot carpet and an H4 headlamp conversion kit. These parts were supplied by RevingtonTR but the subsequent 2015 panel and paintwork was undertaken elsewhere.
The Vendor reports that the overdrive operates in the higher gears through a dashboard-mounted switch rather than the traditional gear-lever arrangement. A discreet battery isolation switch has also been fitted beneath the steering wheel.
The car is currently fitted with Mazda MX-5 seats, installed to improve comfort during the Vendor’s ownership. These were initially believed to be leather but have since been discovered not to be genuine leather. The original Triumph seats remain with the Vendor and can be collected by the successful purchaser following the sale, although they will require restuffing before being returned to regular use. The original factory wheels are also included with the vehicle, with an alternative set currently fitted.
Since the restoration, the Vendor reports that the TR6 has never been driven in wet weather. The hood has also reportedly always been kept lowered during this period.
Purchased by the current Vendor in 1978, the accompanying registration document records the transfer of ownership at approximately 17,000 miles. The car has remained in the same ownership ever since, representing an exceptional 48-year custodianship. During the Vendor’s time abroad, the TR6 was carefully garaged between 1983 and 1998 before subsequently being returned to use. A substantial programme of restoration, mechanical maintenance and improvement followed from 2012 onwards, supported by invoices from Marque21, RevingtonTR and other specialists.
The history file includes a valuation prepared by Marque21 in 2012 and a further valuation undertaken by RevingtonTR in 2014. Both assessments pre-date the bodywork and professional respray completed in 2015. The RevingtonTR report valued the car at between £20,000 and £22,000 and noted that, with further attention to the bodywork, it could potentially achieve a value of up to £30,000. The subsequent 2015 bodywork and repainting were therefore completed after this assessment. The accompanying MOT history provides excellent support for the believed genuine mileage of just 45,089 miles, while the current MOT remains valid until May 2027 with no advisories recorded. Also included are a Haynes workshop manual and numerous invoices supporting the considerable expenditure reported by the Vendor.
The Triumph TR6 remains one of Britain’s most recognisable and desirable traditional sports cars. Styled by German coachbuilder Karmann, it combined sharp, purposeful lines with Triumph’s proven separate chassis and a charismatic 2.5-litre straight-six petrol engine. This example is understood to be powered by the 125 bhp version of Triumph’s 2,498cc overhead-valve straight-six, delivering strong torque, an unmistakable exhaust note and relaxed open-top touring ability. Independent rear suspension, front disc brakes and the availability of overdrive helped make the TR6 equally suited to longer journeys and more enthusiastic driving on winding roads.
Almost 92,000 examples were produced between 1969 and 1976, making the TR6 Triumph’s most successful six-cylinder sports car. Late examples such as this mark the closing chapter of Triumph’s traditional open-headlamp sports-car lineage before the introduction of the wedge-shaped TR7.
Few classics offer the same combination of usability, character and strong enthusiast support as the Triumph TR6. This example stands apart thanks to its remarkable 48-year ownership, believed genuine mileage of just 45,089 miles and extensive programme of improvement by Triumph specialists RevingtonTR, classic car specialists Marque21 and other professionals. The inclusion of the original wheels and seats provides flexibility for those wishing to return the car closer to its factory specification, although the original seats will require restuffing. Alternatively, the RevingtonTR uprated suspension package, reconditioned gearbox, refurbished brake calipers and numerous additional mechanical improvements should appeal to those seeking a more usable and rewarding driver’s car.
Reportedly kept away from wet roads since its restoration and accompanied by an extensive history file containing invoices, MOT records and valuation reports, this is a particularly appealing example of Triumph’s enduring six-cylinder sports car.
