Production run & eligibility
| Chassis code | Z31 |
|---|---|
| Production start | September 1983 |
| Production end | July 1989 |
| First cars eligible | September 2008 |
| Last cars eligible | July 2014 |
Eligibility is counted from the month of manufacture on the build plate of the specific car — not the model year. A 300ZX (Z31) built one month later unlocks one month later.
California is different
The 25-year rule is federal — it clears customs and NHTSA. California additionally requires direct-import vehicles newer than 1975 to pass its own emissions certification, which most JDM imports cannot do without an expensive lab conversion. If you are in California, read our state registration guide before bidding on anything.
