This book explores the development of the early models of the Triumph TRs. Failing in their bid to buy Morgan, the Standard Motor Company decided to design their own sports car. The result was the TRX and 20TS, which outlined the shape of what was to become but which also revealed several teething problems. As these were gradually ironed out, the TR2 came on the scene, soon followed by a TR3, which had more power and body options as well as disc brakes. Later, the TR4A would continue to incorporate improvements such as independent rear suspension. This book provides all the information you need about TR sports cars.
