The Leopard F31's production run lasted for seven years, ending in June 1992 due to lagging sales. Seven years was very long by period Japanese standards, nearly equating the runs of two generations of most Japanese cars of the time. Nobody knows exactly how many Infiniti M30 were produced for the US market, but it has been said that just over 17,000 were made. It is unknown how many were coupés and how many were convertibles; the convertible was only available in 1991 and 1992. 38,000 F31 Leopards were sold in Japan during its seven-year production span.
