The Triumph TR range is amongst the most popular of classic British sports cars on both sides of the Atlantic. TRIUMPH TR - TR2 to 6: The last of the traditional sports cars, as the title suggests, covers the cars from the basic four-cylinder TR2 introduced in 1953 to the hairy-chested six-cylinder TR6 that finally bowed out of production in 1975, to be replaced by the unloved TR7.
