4. Pagani – Horacio Pagani originally teamed up with Lamborghini, doing composite research for them in 1988. The company was called “Pagani Composite Research.” In the late ‘80s Pagani wanted to start building his own car, which was coded as the “C8 Project.” The C8 would later be named the Fangio F1 in commemoration of the F1 champion, Juan Manuel Fangio. For its amazing designs, Pagani is the #4 Most Exotic Car Maker.
