A product of Britain's old Standard Triumph motor company, the TR3 was notable for its low-cut doors. Because it was fitted with plastic side curtains instead of rollup windows, the doors were short enough for the driver to rest his arm on top. From the front, the TR3 was just as distinctive, with prominent headlamp housings and a large egg-crate grille. Although it was the first production car with disc brakes, the TR3 hardly needed them. Its four-cylinder engine produced only 95 hp. Just 10% of the cars built remained in England. The rest were shipped to the U.S.
