Triumph TR4: buying guide and review (1961-1967)

Triumph TR4: buying guide and review (1961-1967) Classic and Performance Car
Triumph TR4 Triumph TR4
The Triumph TR4 is arguably the archetypal ‘hairy chested’ British sports car. Introduced primarily to increase Triumph’s success in the US market, over 71,000 were produced over a six year period. Today, approximately 1650 remain in the UK. 
Mechanically, it shares much with the earlier TR3. The only major upgrade came in the form of a 2138cc engine, bored out from the TR3’s 1991cc lump. Power jumped up to 104bhp, and performance is still more than sprightly enough to keep up with modern traffic. Today of course many are producing significantly more with 130bhp possible thanks to modern improvements.
The major change relative to older TRs came in the form of the body styled by Giovanni Michelotti. Though it caused some controversy upon its release – it replaced the previous swoopy shapes for a much squarer look – the TR4’s looks have aged very gracefully, with details like the headlamps set inboard of the wings giving it a distinctive face. An added benefit of the more slab-sided flanks was that wind down windows could be fitted – a big improvement over its predecessor's rather flimsy side curtains. Inside, the dashboard looks charming, and was one of the first production cars to include adjustable air vents on the fascia. 
On the road, the ride can be uncompromising thanks to the bouncy leaf-sprung rear axle. This was remedied in later models thanks to a revised setup at the back. The updated trailing arm/coil spring system helped it perform better on the track too – in 1966 TR4s achieved a 1,2,3 class finish at the Sebring 12 Hours. 
Which one to buy? 
The only big change mechanically in the TR4’s life was the introduction of independent rear suspension in 1965. This helps to improve the ride considerably over older models, and therefore cars produced after this date are very desirable. Many of these later cars carry ‘TR4 IRS’ badging. 
Beyond that, the options were fairly limited. Wire wheels are fairly common now, though standard items were pressed steel discs. Examples equipped with the optional temporary hard top will always be a plus. Triumph offered the TR3’s 1991cc engine as an option, to allow the TR4 to compete in sub-2000cc motorsport categories, though these examples are rare today. It isn’t uncommon to see some engine upgrades, including – in rare cases – supercharger conversions. 
Some examples sold abroad have since been imported back to the UK and converted to right hand drive. It is possible to tell which cars have been converted from the chassis number - those which end with ‘L’ signify left-hand drive cars. Whether converted or not, L models tend to command slightly lower values than original rhd cars.

Common problems

• Rust can develop from almost anywhere you’d care to think. Particularly keep an eye out for rot on the boot lid, rear wings, doors, sills and A and B posts. It’s also worthwhile taking a very thorough look at the inner wings floor pan, too. Body panels and spares are readily available
• Take a look at the chassis, as the condition of this has a serious effect on the car’s long term viability. Inspect all of the chassis mounts, and get the car on the ramp to check for any serious corrosion issues. Don’t be too afraid to poke holes in anything, but also be careful to look for distortion caused from any recent (or not so recent) accident damage
• While out on a test drive, try out the overdrive function to make sure it works properly (if fitted). Chances are, any problems will be traced back to dodgy electronics, a clogged filter or low oil level, but if not a replacement overdrive unit is not expensive. There are also modern electronic components available to help with reliability
• Check the condition of shock absorbers. Standard parts are fairly cheap (a front pair can be sourced for around £35) but uprated items can cost a couple of hundred pounds for a pair. This is a great and worthwhile upgrade that can transform the TR4’s handling, so a car that already has these fitted is a huge bonus
• Electrical wiring can be patchy – check the condition and make sure everything in the cabin works 
• Each individual TR4's build record can be requested from the Heritage Motor Centre's archives, allowing any potential restorations to be carried out as faithfully as possible
• Check for telltale gunk under the oil filler cap which points towards oil and water mixing – this is a sign that the head gasket has failed
• If you have a mechanic to help you inspect the car, check to ensure all four cylinders are running at the correct compression 
• Leaks are fairly common from both the engine and gearbox, though the less seepage, the better 
• The fabric hood was of a poor quality when it was new, so leaks are likely. Check the interior carpets, as sell as the seats for any signs of damp

Summary and prices

Prices for the TR4 are still fairly accessible for most classic car enthusiasts. Values for the most immaculate models top out at about £30,000, though race-prepped versions can be higher still. However, there are just as many very clean examples for closer to £20,000, too. 
Good runners with minor niggles are closer to £16,000, and anything significantly cheaper than that will generally require a serious amount of work.

    An increasingly rare find being as it is an early UK delivered TR4 with Surrey Top. Remember, some 90% of Triumph production in this period was destined for an overseas market so a UK car has a certain cache. Being an early car, it also still retains its beautifully patinated TR3a style seats, which handily can also accommodate a taller driver. Indeed, the previous owner to us of some 12 years was some 6’ 4” himself and fitted comfortably. We’re not claiming this car to be a concours contender as it stands, though little effort from an enthusiastic owner would certainly enhance its chances. Instead, with a significant drought of good sub-£30,000 classic sportscars we’re pleased to offer this to someone who will enjoy using it, rather than just polishing it. Supplied through F. Guyver & Sons Limited of Stratford Upon Avon in 1962 its original colours were Spa White with Black leather interior. Options included heater, windscreen washer, hard-top, sun visors, Michelin X tyres and overdrive. In 2011/12 this car was stripped to be repainted. At the same time, four original wings sourced from the USA were married to the car, and the sills replaced. A full respray and re-chroming of the brightwork also took place as documented by photographs and a host of receipts. Later, in 2015, the engine head was rebuilt too. Our car further benefits from a Phoenix exhaust and manifold, electric ignition and Petronix Flame Thrower coil. A known car amongst the TR Register, ‘HFO 754’ was featured many times in the Rimmer Bros catalogue. Currently undergoing final preparation, the intention is to get the car back to looking as it did in period, with steel wheels, chrome hub caps and perhaps devoid of the Lucas fog lamps, albeit, they’re bloomin’ handy for a late run back from the pub!

The car was based on the chassis and drivetrain of the previous TR sports cars, but with a modern Michelotti styled body. 40,253 cars were built during production years. The TR4 proved very successful and continued the rugged, "hairy-chested" image that the previous TRs had enjoyed.

The standard engine produced 105 bhp (78 kW) paired with 4 speed full synchromesh manual gearbox and overdrive as an option. The TR4 had a number of racing successes in America.
