What owners say
Insight
Overall
Sentiment varies significantly by generation. For the first-generation (circa 2000-2006), owner feedback is highly positive regarding its unique character, describing it as a "fucking blast to drive" with a manual transmission, lightweight (approximately 1,800 pounds), and VTEC engine, despite acknowledging its lack of power for highway merging. This generation is viewed as a fun, ultra-efficient commuter.
Best version to buy
