Quick answer
A 2018 Nissan Altima in good condition with average mileage (about 100,000 miles) is worth roughly $10,450 in a private-party sale — a fair range of $9,600 to $11,300, or about $12,000 at a dealer. 2018 is not on our years-to-avoid list, so condition, history, and maintenance matter more than the model year here.

- Hood latch and passenger airbag sensor recalls on several years — check VIN
