InfinitiJ30
The Infiniti J30, marketed as the Nissan Leopard J Ferie in Japan, is an executive car. The J30 went into production on April 7, 1992 as a 1993 model to replace the M30, and was launched in the United States after its competitors, the Lexus GS and Acura Legend. The car was sold in the mid-size sedan segment between the smaller G20 and the larger Q45, both by size and price. The small interior resulted from its rounded styling uncharacteristic of the crowded executive car class, which is now considered an early variant of a four-door coupé.
