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.
Known issues
Overall
Sentiment is mixed and heavily dependent on ownership expectations and maintenance history. Long-term owners frequently report high reliability and durability, with many vehicles reaching 150,000 to 230,000 miles with minimal major issues, describing them as running "like a dream" or being "rock solid." The vehicle is consistently praised for being a fun, affordable, and practical entry-level sports coupe, offering decent power, fun handling, and a unique look. However, a significant portion of feedback highlights a pattern of specific mechanical and electrical failures, including premature clutch wear, timing belt/water pump service as a critical failure point, and various electrical gremlins.
Best version to buy
Insufficient owner data available to declare a consensus "best" trim. The GT trim with the V6 engine is mentioned, and the 6-speed manual transmission is noted as a desirable configuration.
