6. Mitsubishi Diamante
The Mitsubishi Diamante arrived in 1992 as the brand’s answer to luxury sedans such as the Toyota Cressida. With a smooth V6 engine and an array of advanced features—including electronic climate control and premium sound—the Diamante delivered a sophisticated driving experience. It exuded a sense of modern luxury, appealing to those who craved refinement without sacrificing performance. As MotorWeek observed, the Diamante helped Mitsubishi carve out a spot in the competitive upscale sedan market.
