Overall
Overwhelmingly enthusiastic sentiment for legendary sport sedan regarded as Honda's finest achievement, praised extensively for timeless elegant styling aging gracefully 15-20+ years later, bulletproof K24 engine enabling routine 200,000-300,000+ mile operation (documented examples exceeding 525,000 miles), engaging driving dynamics balancing sportiness and comfort creating "fast go-kart" sensation, perfect compact size filling gap between Civic and Accord, exceptional build quality with vault-like door closing feel (Japan-built VIN "J"), excellent manual transmission option (6-speed creating enthusiast following), affordable maintenance with Honda parts availability, and unique luxury features unavailable in mainstream Honda products. However, criticism includes weak low-end torque requiring high RPM driving (VTEC engagement 6,000 RPM), cramped rear seat legroom, expensive 1st generation parts (steering racks, power steering pumps, alternators not shared with US models), door speaker failures requiring aftermarket replacement, oil consumption issues (2009-2014 models), poor fuel economy versus modern standards (22-25 MPG combined typical), soft Honda paint with clear coat failure, and chronic rocker panel rust (Canada/salt belt climates). Overall consensus: 1st generation 6-speed manual (2004-2008, especially 2007-2008 facelift with upgraded K24A2 engine) represents ultimate driver's TSX achieving cult status, while 2nd generation (2009-2014) offers more refinement and features though less engaging dynamics.
Best version to buy
1st Generation 6-Speed Manual (2007-2008 facelift) The 2007-2008 facelift years with upgraded K24A2 engine (203 hp versus 200 hp pre-facelift), revised cylinder head design adding 5 hp/torque, 6-speed manual transmission, improved interior materials, steering wheel controls, power passenger seat, resolved early production issues (AC condenser, alternator, starter reliability improved) represent ultimate TSX specification. Manual transmission transforms driving experience enabling full engine exploitation and eliminating automatic transmission whining.
Known issues
Overall
The sentiment is overwhelmingly positive, with the Accord consistently praised as a benchmark for reliability, practicality, and long-term value. Owners across multiple generations express deep satisfaction, describing their vehicles as "bulletproof," "reliable as fuck," and capable of lasting over 200,000 miles with basic maintenance. The car is widely recommended as a comfortable, spacious, and fuel-efficient family sedan that excels at daily driving.
Best version to buy
For the 9th generation (approx. 2013-2017), the V6 engine, particularly in coupe form with a 6-speed manual transmission, is highly regarded for its smoothness, power (noted as being underrated at nearly 300 hp), and engaging driving character. For the 10th generation (2018-2022), the 2.0-liter turbocharged engine is strongly preferred over the 1.5T, with owners noting it is a detuned Civic Type R engine with high tuning potential and a superior, more reliable 10-speed automatic transmission.
