What owners say
NSX
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.

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.

The RX-7 is consistently described as a "dream car," a "joyous" driver's car that feels like an extension of the driver, and a vehicle that garners significant positive attention. However, this adoration is heavily tempered by a universal and very frequent consensus on the demanding, expensive, and specialized ownership experience.
Best version to buy

Known issues
- ⚠Rotary engine reliability and maintenance demands: Requires meticulous care including mandatory premium fuel, frequent oil changes, proper warm-up, and vigilant cooling to avoid catastrophic failure from knocking or overheating.
- ⚠High operating costs: Poor fuel economy (reports of 16-20 MPG, or as low as 8 MPG on modified examples), constant requirement for premium fuel, and high oil consumption by design. Frequency: very frequent.
- ⚠FD-specific turbo system complexity: The sequential twin-turbo system in the FD is described as over-complicated and prone to issues with vacuum lines and pneumatic controls, leading many owners to simplify or convert to a single turbo set…
