2018 Honda Civic vs 2018 Mazda Mazda3
Two compact cars, compared on what actually matters when you're buying used:
what breaks, when it breaks, and what it costs you.
2018 Honda
Civic
8/10
Sharp to drive, cheap to run, and mechanically solid — but the steering rack and Takata-era fuel pump gremlins mean you buy this one with the recall letter in hand.
VS
2018 Mazda
Mazda3
8/10
A Miata in a hatchback suit — buy the 2.5L, avoid the cracked screen, and enjoy one of the last genuinely fun economy cars.
Dead heat: both score 8/10. The tiebreaker is which specific car you find.
