2018 Mazda Mazda3 value

By Hari Vinayak · Updated 2026-06-12

Quick answer

A 2018 Mazda Mazda3 in good condition with average mileage (about 100,000 miles) is worth roughly $9,200 in a private-party sale — a fair range of $8,450 to $9,950, or about $10,600 at a dealer. 2018 is not on our years-to-avoid list, so condition, history, and maintenance matter more than the model year here.

What to check before you pay

  • Rust on rear wheel arches and rockers, 2010–2013 especially in salt states — look closely and check under trim
  • 2014–2018: LED headlight unit failures — a single replacement can run $800+; verify both work fully
  • 2010–2013 2.0/2.5: generally solid; check motor mounts and clutch wear on manuals
