By Hari Vinayak · Updated 2026-06-12
Quick answer
A 2021 Mazda Mazda3 in good condition with average mileage (about 62,500 miles) is worth roughly $13,050 in a private-party sale — a fair range of $12,000 to $14,100, or about $15,000 at a dealer. 2021 is not on our years-to-avoid list, so condition, history, and maintenance matter more than the model year here.

Compare the best and worst Mazda3 yearsWhat 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
