Before the world got swept up in crossovers and SUVs, Mazda quietly built a sedan that dared to play in the luxury league. The Mazda Millenia—sleek, understated, and technologically ambitious—wasn’t just another plush commuter.

Though it never earned the same prestige as a Lexus or Acura, the Millenia was proof that Mazda could build a luxury car ahead of its time.
