HistoryThe TR7 was sometimes called ‘The Wedge’ because of its distinctive body shape. A major move away from the traditional TR range in both styling and engineering technology that reflects Triumph’s days in the hands of British Leyland. Around 110,000 were built between 1974 and 1981. The greatest change being the monocoque, not chassis built, resulting in a complete character change in handling, noise and vehicle harmonics. Although some enthusiasts do not consider it a ‘proper’ TR it has become increasingly popular providing modern motoring (creature comforts such as wipers that wipe windscreens and heaters that keep the driver warm!) combined with the pleasure of owning a classic car.SpecificationThe TR7 engine is 1998cc and based on the Triumph Dolomite. To achieve the low body profile, the engine sits at an angle under the bonnet. Originally sold in the UK with a 4 speed manual gearbox (due to British Leyland’s lack of capacity of 5 speed transmissions), the later models are 5 speed or automatics.Coil springs with telescopic twin shock absorbers and anti roll bars, both front and rear, gave a soft and comfortable ride expected by the US market. Options were available, via the Unipart catalogue, for harder springs more likely to suit the European taste, but these were not available as standard on a production car. To reach world markets the car was technically compromised with duplicate systems, such as pop up headlights also having a manual system fitted, enabling one car to conform to the variety of differing specifications across the world. A difficult mission because even Florida and California have different legal requirements. What to look forLike all cars of this era, it is prone to rust. Rust usually starts in the seams at the spot welds. Some cars were better protected than others and it is possible that unpainted steel pressings were left exposed to atmospheric corrosion during periods of industrial strife, and different production techniques would have varying effects. I know of one car, built 20 cars later than my own, which rusted away in four years. The rogues that would start to rust in the middle of panels, giving TR7s such a bad press, are probably no longer in existence.Standard rust checklist Inner wings to McPherson strut housings Corrosion to lower rear swing arm to attachment to the floor. (Rear suspension) The H deck, adjoining rear wings Front bulkhead to floorpan seams (engine compartment & under front wheel arch) Sill sections Windscreen pillars As with any car get under it and look. Check for signs of filler. TR7s are possible to repair, but it takes time and effort and requires a different approach than earlier TRs due to the method of body construction. Interior colours and styling varied with production sites, Speke, Canley and Solihull cars are all different. Interiors can be altered to suit personal taste. There are a number of outlets providing parts for TR7s and 8s, so if you are capable of maintaining and servicing the vehicle, a TR7 should not present too many problems to keep it on the road. Insurance is obtainable at reasonable rates for younger drivers if you shop around. |
