The Spitfire was one of Triumph's most successful models throughout the 1960s and 70s, and its high-performance sister car, the GT6, was received with equal acclaim. Both cars remain as popular today as when there were in production, their lasting success ensured not only by their attractive styling and performance, but also by their straightforward construction and the ease with which they can be maintained. John Thomason's meticulously researched book charts their development, covering for each the many changes to the body and chassis, engine and engine bay, interior and transmission and suspension. Thoroughly cross-referenced, this is an easy-to-use and quick reference guide, invaluable to owners wishing to maintain or restore their cars to be as near factory specification as possible.
