15. Datsun 510
When Datsun unveiled the 510 in 1967, most people considered the boxy design to be modern and elegant. In fact, this little car was advanced, and not just by its looks, but also by its mechanics and independent rear suspension. The base engine was a 1.6-liter four cylinder with 96 HP.
However, thanks to the 1.8-liter unit with its twin barrel carburetors; this little car had some power and convincing performance. It was also available as a sedan, two-door coupe, and wagon. Soon, it became the popular base for lots of modifications.
