11. Mazda Millenia
The Mazda Millenia aimed for the luxury segment with refined styling and an innovative Miller-cycle supercharged engine.
Its smooth ride and upscale features set it apart, but it was often overlooked in favor of more prestigious Acura and Lexus models.
AutoTrader’s analysis highlights its unique engineering and underrated status.
Despite its merits, the Millenia never achieved the recognition it deserved, making it a hidden treasure among 2000s luxury sedans.
