4. Nissan: 11.6%
Nissan has always been the Japanese automaker trying to cater to all markets with its diverse model lineup. The 370Z has been a home run for Nissan and most definitely helped contribute to the 11.6 percent of younger buyers. But it’s hard not to see a bunch of successful models for the Gen Y demographic, including the Versa, Sentra, Altima, Murano, and Juke.
