The original Z — sold in the US as the Datsun 240Z (1970–1973, 2.4L L24 six), then 260Z (1974, 2.6L, added a 2+2) and 280Z (1975–1978, 2.8L fuel-injected). A long-hood fastback that made affordable performance a mainstream idea.

Reliability & ownership notes

  • Verify chassis code, engine, transmission, emissions equipment, and production date before ordering parts. Inspect rust and prior structural repair, cooling and fuel systems, timing-drive history where applicable, turbocharger condition on forced-induction cars, and modification quality.
