The iconic car was split into two generations: S13 and S14. The S13 generation was the introduction of the 240Sx, and it was designed to reflect the Nissan S platform. The S14 came next and ran from 1994 to 1998.
Depending on when your dad owned his 240Sx, he might have a preference. Lovers of the S13 appreciate the strength of its chassis—or framework—for drifting. Others love the strength of the S14 model, but the moderate 2,000 sold in 1998 compared to the over 68,000 S13s sold in 1989 implies customers had a favorite.
Either way, these rowdy rides are a rare breed. You might have to connect with missile-car lovers to get your hands on one for your dad.
