Question: what is the difference between nissan xterra x and s?
Answer: Nissan offered the Xterra in three trim levels: X, S and Pro-4X. The first two were offered in either rear- or four-wheel-drive versions, while the Pro-4X was 4WD-only. ... In 2003, both the regular and supercharged V6 engines received slight power boosts, and the Xterra was treated to trim and styling tweaks.
