Overall
Overwhelmingly positive sentiment approaching legendary reverence for first-generation model, widely regarded as revolutionary supercar redefining exotic car reliability, usability, and everyday drivability. Praised extensively for exceptional Honda build quality enabling routine 200,000-300,000+ mile operation without major mechanical failures, precise handling dynamics teaching Ferrari and Porsche lessons in chassis balance, comfortable ergonomics allowing daily driving unlike temperamental Italian competitors, and timeless aluminum body construction preventing rust. The naturally-aspirated 3.0L V6 producing 270-274 hp delivers linear, predictable power delivery with intoxicating VTEC engagement at 5,800 RPM and 8,000 RPM redline.
Best version to buy
3.0L Manual Transmission (1991-1997, pre-facelift) The 1991-1997 pre-facelift models with 5-speed manual transmission represent purest NSX expression - lightweight aluminum construction (approximately 3,000 lbs / 1,361 kg), naturally-aspirated 3.0L C30A V6 producing 270-274 hp, fixed headlights (1991-1993 pop-ups add 60 lbs / 27 kg), manual steering maintaining ultimate feedback. The 1995+ NSX-T targa variant adds removable roof panel but 100+ lbs (45+ kg) weight penalty and reduced chassis rigidity.
Known issues
Overall
