The second-generation Saab 900 (also referred to as the GM900 or NG900 among enthusiasts) was built on GM's Opel Vectra platform as a replacement for the "classic" first-generation Saab 900. This all-new 900 was produced in the 1994 through 1997 model years. For 1998 it received a number of minor, mostly mechanical improvements and was renamed the Saab 9-3 (YS3D) (in most markets; in the US the name change was introduced for 1999). As the 9-3, the NG900 was produced through 2002.
