21. Nissan 240Z
The 240Z was the first highly successful Japanese sports car on the American market. An automotive legend, it is still highly desirable, even today. But some critics say it is a copy of several European designs. Nevertheless, the 240Z has managed to win consumers over and even create its own segment.
The early models got 150 HP from a 2.4-liter six-cylinder, which was more than enough for a lively performance. But those 150 HP engines are obsolete nowadays. However, many 240Z owners have installed a V8 in their cars to give them just enough grunt to keep up with modern sports cars.
