The TR4 brought Triumph (Finally) into the 1960s when introduced in 1961. Sporting rollup windows, a larger engine, a useable trunk (Boot) and numerous other improvements over it's predecessor, it set the stage for the TR4-A, TR5 (TR250 in U.S.) and the TR6.
On a personal note: This is the shirt I usually wear when driving my TR4.
