Shop By Service Type
Built by Mitsubishi Motors between 1990 and 2005, the Mitsubishi Diamante was a full-size sedan offering good performance and handling, a comfortable cruise, and a well-refined interior . Substantially, it is a well-balanced sedan that provides reliability typical for Mitsubishi. Chosen as the Japan Car of the Year in 1990, the Mitsubishi Diamante was a worldwide good seller. The second generation was introduced in 1995, featuring a more curvaceous and appealing body shape, introducing as well several technological innovations. After a major and quite radical restyling in 2003, the export to the U.S. market was ceased in 2004 and the production was discontinued one year later.
Reliability is one of Mitsubishi’s winning cards, but a thorough check of your sedan on a regular basis is always recommended as mechanicals as well as other components can break or wear out. Moreover, when it comes to the environment protection, we warmly recommend an even more accurate monitoring of the emission control system. We offer all Mitsubishi Diamante emission control parts you might need at our online shop, offering long-lasting and high-quality replacement parts.
