Specs side by side
What owners say
RSX
Overall
Deeply divided sentiment for sport compact coupe, polarizing enthusiasts between passionate Type S advocates versus dismissive critics of base models. Type S (K20A2/K20Z1 engine, 200-212 hp) praised extensively for rev-happy i-VTEC engine delivering thrilling 8,000 RPM redline, precise 6-speed manual transmission, nimble handling dynamics, practical hatchback versatility, and exceptional Honda reliability enabling routine 200,000-300,000+ mile operation. However, base model (K20A3 engine, 160 hp, 5-speed manual or automatic) criticized severely as underpowered, boring to drive, and offering insufficient performance advantage over standard Civic Coupe to justify RSX badge.
Best version to buy
Type S with 6-Speed Manual (2005-2006) The 2005-2006 Type S models represent ultimate RSX specification combining 212 hp K20Z1 engine (versus 200 hp K20A2 2002-2004), improved interior materials, refined suspension tuning, and final production year collectibility. Six-speed manual transmission absolutely essential - Type S automatic extremely rare and universally condemned.

Overall
Mixed sentiment, heavily dependent on generation and powertrain. The Mazda 3 is widely recognized for its fun driving dynamics, upscale interior quality for the class, and strong reliability, particularly for models equipped with the long-running 2.5L Skyactiv engine and 6-speed automatic transmission. Owner feedback positions it as a compelling, more engaging alternative to mainstream competitors like the Toyota Corolla and Honda Civic.
Best version to buy
Insufficient owner data available to declare a consensus "best" trim or version. The Mazda 3 Turbo is mentioned as a desirable performance variant, though one owner reports catastrophic reliability.
Known issues

- ⚠Outdated powertrain technology: The Skyactiv-G engine platform, while reliable, is viewed as lagging behind newer hybrid competitors in both performance and fuel efficiency, contributing to poor sales. Frequency: recurrent.
