Datsun 240Z & Fairlady Z S30: USA Buyer Guide
The Datsun 240Z is an icon, but a Japan-source brief must distinguish the North American HLS30 from the Japanese Fairlady 240Z and 240ZG. Mirai can search original S30-family cars with documented L24 identity, sound shell and export provenance.

Datsun 240Z models and factory specification
Factory identity and the actual manufacture date determine which auction path deserves a closer look.
Nissan’s Heritage Collection says the Fairlady Z S30 began as a 2000-series car in Japan in November 1969. The 240Z was initially a North American export model; Japan added 240Z, 240Z-L and 240ZG in November 1971. A Japan-auction listing called “Datsun 240Z” may therefore be a Japanese Fairlady, an exported HLS30, or a modified S30. Document the original market and chassis before bidding.
Factory references: Nissan Heritage: Fairlady 240ZG (1972 HS30 factory record and November 1971 Japan 240Z launch; checked September 26, 2026). Nissan Heritage: 1973 S30 rally car (1973 HLS30 competition record; not a standard production specification).
| Candidate path | Factory context | Buyer check |
|---|---|---|
| HLS30 export 240Z | North American Datsun identity | Trace chassis and market history. |
| Japanese Fairlady 240Z | HS30-family L24 car | Check original trim and export papers. |
| Fairlady 240ZG | G-nose and overfender specification | Prove factory ZG hardware and provenance. |
Historical records establish representative configurations; the individual auction car may differ by date, grade and modification.
How to buy the right S30 Z from Japan
Turn a model preference into a defined auction search and an evidence-backed bid decision.
Decide whether your target is export-market 240Z, Japanese 240Z or 240ZG. That decision controls identity evidence and value. Japan auctions can contain all three descriptions, so the chassis record matters more than a familiar badge.
Order detailed corrosion and repair photographs, underbody images, cold-start video and a review of any restoration invoices. A cheap-looking classic with deep structural rust can be the costly choice.
Mirai can compare lots from major Japanese auctions, obtain the auction-sheet disclosures and help request more evidence on serious candidates. Ask for a lot-specific landed-cost and shipping estimate; currency, freight and auction results change, so this guide does not publish a fixed vehicle price.
Known problems and model-specific inspection points
Use these checks to test the specific factory identity and condition, not just the auction grade.
| Area | What to check |
|---|---|
| S30 corrosion | Inspect sills, floor pans, frame rails, battery tray and rear wheel arches closely. |
| G-nose authenticity | For 240ZG, compare nose, lamp covers, overfenders and period documents. |
| L24 originality | Match block, carburetion and gearbox to the claimed version. |
| Prior restoration | Request bare-metal/repair photographs and inspect seams beneath fresh paint. |
| Suspension and brake conversion | Document altered struts, brakes and wheels relative to the intended use. |
What drives value in this market
Compare condition and provenance tiers without attaching a price that will age with the next auction.
Sound original metal, documented market/chassis identity, L24 configuration and high-quality restoration records lead the value ladder. Genuine 240ZG specification is a separate provenance tier; a cosmetic G-nose conversion should be priced as a conversion.
A strong candidate file connects chassis and engine identifiers with the export certificate, auction sheet, mileage trail, service history and independent inspection. Read grade and repair markings alongside photographs. Originality is most valuable when it is documented; a modified car needs an equally clear account of parts and workmanship.

USA import: age, engine, customs and state title
Apply four different screens to the exact auction vehicle and its destination.
- Manufacture date. NHTSA’s current import FAQ (checked September 26, 2026) counts the 25-year FMVSS exemption from actual manufacture and uses HS-7 Box 1. A model-year label is not enough.
- Original engine. EPA’s importing guidance, updated September 1, 2026, ties the over-21 provision to the same engine model and configuration originally installed.
- Entry file. CBP’s Article 000001340, published February 13, 2026, identifies DOT HS-7 and EPA 3520-1 declarations. Align ownership, export and chassis documents.
- Destination state. Find the current agency through USA.gov’s state directory. California DMV’s imported-vehicle page (checked September 26, 2026) illustrates its separate direct-import document and emissions requirements.
Mirai Auction Portal: filter real candidates across Japan
Mirai offers exclusive portal access to customers after inquiry. It covers major Japanese auctions and supports robust filters around a U.S. buyer’s brief.
Start with factory model, chassis, manufacture window and original engine. Narrow by mileage, grade, repair history, modifications and the inspection evidence that matters for your chosen variant. Then compare lots and ask Mirai to review a shortlist.
What a U.S.-focused shortlist means
The search prioritizes age, identity, engine, paperwork, condition and destination-state concerns. Listings are not automatically eligible, registrable or Mirai-owned.
Datsun 240Z buying and import FAQs
Direct answers for the U.S. buyer’s first shortlist.
Was every Japan-market S30 originally marketed as a Datsun?
No. Nissan distinguishes Japanese Fairlady Z and later Fairlady 240Z grades from export-market Datsun cars.
Does a G-nose alone prove a factory 240ZG?
No. Verify chassis, documents and original ZG-specific hardware.
Is a fresh paint job enough to establish structural condition?
No. Inspect the metal, repair record and underside seams.
Can Mirai find a S30 Z for sale through Japanese auctions?
Yes. Mirai can filter major Japanese auctions for a documented S30 Z candidate and arrange exclusive customer portal access after inquiry; availability changes by auction.
Is every S30 Z old enough for the U.S. 25-year route?
Yes. The production years covered here have passed 25 years by September 2026; still document the actual build date and check engine and entry papers.
Can an engine-swapped S30 Z use EPA’s over-21 provision?
Generally no. EPA requires the same engine model and configuration originally installed for that provision.
Does federal entry guarantee a state title?
No. The destination state separately controls title, inspections, emissions and road use.
Does California registration follow the federal 25-year route automatically?
No. California DMV applies its own direct-import registration documents and emissions requirements.
Is an auction grade enough to judge condition?
No. Grade helps triage lots, but structural photos, the auction sheet, history and inspection establish the condition tier.
What moves S30 Z value most?
Factory originality, structural condition, mileage evidence, service records and matching identity documents set the value ladder; this guide gives no fixed prices.
Is the Mirai Auction Portal public inventory?
No. Access is exclusive to Mirai customers after inquiry. A displayed lot is not necessarily Mirai-owned stock or approved for U.S. entry.
What information should I send Mirai first?
Send your destination state, preferred S30 Z variant, intended use and budget range. Mirai can build a filtered auction shortlist and request candidate-specific evidence.
