The Dignity and Proudia's combined volumes fell far shy of Mitsubishi's estimated 300 sales per month, and they were available for only fifteen months from their introduction on February 20, 2000, before Mitsubishi's financial difficulties forced the company to discontinue both models in an effort to streamline its range and reduce costs. Sales of the Proudia in Japan were affected by the fact that it didn't comply with Japanese Government dimension and engine displacement regulations for "compact" sized cars and Japanese buyers were liable for additional taxes, and the economic fallout due to the collapse of the "bubble economy". The Proudia's engine displacement also made Japanese buyers liable for higher annual road tax.
