The Triumph TR6…a great British sportscar built between 1968 and 1976 by the Triumph Motor Company. The Triumph T6 was the most successful car in terms of sales of all the TR range to this point. Over 90000 TR6s were produced over the models lifespan of which the vast majority were exported.

TR6s had a 2.5litre straight six under the bonnet that produced 150bhp in the early cars (up to 1972) and 125bhp in the later de-tuned cars. All UK TR6s were built with fuel injection with the US versions (TR250s) using carburetors. The UK carburetor version would do 120mph and accelerate from 0-60mph in 8.2 seconds.

The transmission was a four speed manual with optional overdrive. On older models the overdrive was fitted to second, third and fourth gear and on later models only on third and fourth.

The Triumph TR6 can be a great car to own and can be enjoyed relatively cheaply in comparison to something like an Austin Healey 3000.

There are inevitable a few issues (As with most triumphs) that can cause a lot of pain if not checked thoroughly before making a purchase!

As with most British classics, the TR6 is susceptible to rust almost anywhere although there are some areas that can be particularly tiresome to fix. The good news however is that parts for the car and skilled labour is not hard to come by and in most cases not too costly.

The first place, maybe the most important and certainly the most costly area to check for rot is the chassis and in particular the suspension mounts. Rust and corrosion here is a guaranteed MOT failure and an expensive fix. Of course the chassis could be replaced in its entirety but not really a viable route to take without very deep pockets.

Other areas to check include the usual culprits, the floors, the boot floors and sills. Behind the headlights and the rear wings at the tips are also common problems on the TR6.

Rot free TR6s in the UK are incredible difficult to find as are many British made classics. The USA is always an option if you are looking for a clean original car, the cost of converting to RHD is not expensive and any company with anything about them could do it for you. There is of course the downside of the TR250 running carbs not fuel injection but if you can put up with a little less power and an older fuelling system you are likely to get a better car for your money.

In the main the engines are reliable and are good for 10000 at least in most cases. Finding a car above this mileage that is still running smoothly is unlikely unless the engine has been rebuilt. Signs that you may need to think about a rebuild include low oil pressure, excess smoke and noisy thrust bearings. Engine parts are plentiful however and costs are relatively low so if a rebuild is needed it would be worth investing in to have the most enjoyable driving experience.

The one common issue with a TR6 gearbox is the electronic overdrive. This often will need an overall but again with almost everything we have discussed in this post the cost and time involved in fixing this is minimal.

The interior is rarely a problem and is mainly vinyl and plastics which are simple and inexpensive to replace.

TR6s usually came with steel wheels and if in bad condition can be sandblasted and refished at low cost. Some of the early models were available with 72 spoke wire wheels which prove more of a problem. If these are damaged the best course of action is usually to replace the wheels in their entirety.

In conclusion the Triumph TR6 is a simple, relatively inexpensive to keep classic British sports car.  With just a few checks and time spent on seeking out common problems you can have a lot of enjoyable motoring in these cars. The great sounding straight six is a joy to hear and has plenty to give in terms of power and cruising ability. If you are looking for a great example then consider a restored car or one that’s imported from the states. The TR6 is certainly an appreciating classic car so for an investor or collector or just a common or garden enthusiast these 6 cylinder roadsters are always worth owning.
