Stunningly presented in Mimosa Yellow over black interior with wood veneer dashboard, this example of Triumph’s TR6 roadster has been owned by the current keeper for the past 14 years. It is presented for sale with Triumph’s 2.5-litre straight six engine, attached to a four-speed manual transmission with overdrive. During its time with the seller, it has been subject to a full body and chassis restoration, carried out in 2010. ‘NMO 644L’ has also had adjustable gas shock absorbers fitted, a Revington throttle body conversion, six-branch stainless steel manifold and twin stainless steel exhaust system, a high-torque starter motor, drilled and grooved disc brakes with competition-standard pads and stainless steel braided hoses, and an emergency bonnet release catch added.

‘NMO 644L’ is offered with a wealth of paperwork, including invoices of work carried out by the vendor during the Triumph’s extensive restoration, and British Motor Heritage certificate, showing that it was built in December 1972, and dispatched from the factory in January 1973, as a home-market right-hand drive model. Showing an indicated 85,799 miles on the odometer, past MOTs seem to show minimal usage over the past few years. Now more than a decade on from the restoration, ‘NMO 644L’ is still regarded by the vendor as being in ‘good’ condition across the board, from engine and transmission, to electrics, interior, paint, and bodywork.

The Triumph TR6 was launched in 1969, having had a short gestation caused primarily by financial shortcomings. It was a time of quick turn-arounds for the British sportscar maker, since its predecessor – the TR5 – was only in production for a little over a year, and was itself essentially just a larger-engined version of the Michelotti-designed TR4 from 1961. For the TR6, Triumph engaged Karmann in Germany to restyle the TR5, which it successfully did, retaining many of the same key components and dimensions, but updating the look to that of a roadster ready for the Seventies. Because of the limited budget and engineering constraints placed upon Karmann, the TR6 was turned around from sketches to production in less than a year, with new wings, bonnet, external trim, front and rear panels, and boot the only changes. The chassis and engine remained, in the latter’s case the 2.5-litre straight six, available initially only with a carburettor, but quickly became available as a petrol-injection unit as well, and Overdrive was available as an option from the factory too. By the time the TR6 ended production, more than 90,000 models had been produced.
