B17 Sentra is among the most affordable used compact sedans available. The 1.8L engine itself is reasonably reliable — the Xtronic CVT is the buyer risk. CVT failure mirrors the Altima pattern when NS-3 fluid was not changed every 30k miles. Service history is everything on any CVT Nissan.

Ask for CVT fluid service history. Test highway acceleration — any shudder or hunting = CVT wear.
