Triumph TR-4A (1964 – 1967)

Revised Roadster keeps up with the times
With the best of British at its heels

Triumph had earned itself a reputation for capable sports cars since the early fifties when they introduced the TR-2. Since that time they continued to develop the Roadster by refining the engine and tweaking the aesthetics to suit changing styles. In 1964 the Triumph TR-4A was launched with very little exterior change from its predecessor the TR-4,however underneath was a different story.

The original TR-4 was launched in 1961 with a radical restyle by the famous freelance designer Giovanni Michelotti. The new improved roadster had sharp modern lines and wind up windows with face level air vents, a first of its kind. Purists accused Triumph of going soft with these practical features and the Americans were so worried they continue to order the TR-3A’s from the UK for fear the new model wouldn’t sell. The TR-4A had a wider track and had gained independent rear suspension making Triumph the only British car manufacturer to have IRS under all cars in their line up.

Today the TR-4A is one of the best classic British roadsters of its time and combines traditional qualities and state of the art engineering together to make the perfect car for Sunday morning drives in the country, sounds perfect.

With values constantly rising the classic range of Triumph Roadsters will always be of historic value as well as being a joy to drive on the open road.


As values continue to increase on these classic roadsters if you’re to buy one make sure it’s worth it before you part with your hard earned cash. Take a good look at the exterior and make sure all the panels align neatly as this could mean poor repairs.

Corrosion is the classic cars nemesis and on a vehicle from the sixties it could be lurking anywhere so check carefully. Bubbles in the paint work are a giveaway so inspect where panels meet for signs. Other significant areas to check are sills, wings, boot floor and bulk head.

Engines are strong and long lasting which means they are good for about 150,000 miles before a rebuild. The beauty of these engines is lowdown torque resulting in no need to over rev to get the best out of the car; they perform at their optimum around 4000 rpm. Do check for leaks however and listen to the car on your test drive as big end rumble can be bad news.

Transmissions can have problems so make sure the gears are smooth as they are prone to failing synchromesh also make sure the overdrive is working correctly. Steering on the TR-4A is accurate so anything else could be a problem such a worn rack or perhaps rubber mounts.

Brakes are front discs and rear drums so make sure it stops straight. The handbrakes are notoriously weak so don’t expect too much and best to leave it in gear when you park.

Electrics can have their problems, so go for one with an alternator (optional on the TR-4A) and make sure everything works. Also Interiors can prove expensive to replace so make sure it’s in good shape.  Also interiors can prove expensive to replace so establish it’s in good shape, making sure to check carpets for any damp.

Perhaps the rarest production TR4 model is the Dove GTR4 (and GTR4A) – a TR4 rebuilt as a coupé by a specialist coachbuilder for the Dove dealership in Wimbledon, London; only 43 were produced with only a dozen of these still in existence today.

Mark Wilkinson (Managing Partner of Heritage Classic Car Insurance) says

“We are all familiar with the phrase if it’s not broke, don’t fix it. Well this certainly would apply to the Triumph TR models; they have always been prolific sports cars that evolved as did technology and engineering, ensuring they always remained current. The quintessentially British roadster is still a great weekend drive and plays a huge part in historic motoring today.”

Volkswagen Karmann Ghia Type 14 (1955 – 1974)

Volkswagen had great success with their people’s car the Beetle and now it was time for something a bit more exotic. The Type 14 or Karmann Ghia was debuted at the 1953 Paris Auto Show as a styling concept for Ghia. It was a 2+2 coupe with hand-shaped body panels smoothed with English pewter normally used in the production of top end cars. The Karmann Ghia adopted the same floorpan and engine variations as the Beetle and so it always looked a lot faster than it actually was.

TVR Griffiths (1992-2001)

With the birth of the 1990’s we saw TVR go back to the drawing board with their new creation. The trick was producing a short chassis sports car producing in excess of 230 bhp capable of speeds over 150 mph. They of course did and it was called the TVR Griffiths.

MG C (1967 – 1969)

The MGB GT was a perfectly good sports car in itself when it arrived in 1965 with conventional GT styling of the time at a fraction of the going price, However the MG was a little sluggish when it came to its competition such as the Triumph TR4 and soon after the TR5 which was exactly what MG had in mind when it produced the MGC. The six cylinder 2912cc engine was MG’s answer to fill the gap in the BMC’s range with the demise of the big Healey’s and with such powerful competition from its rival namely Triumph the MG C was born.
