1972 Datsun 240Z — Should You Buy One?

Typical asking price: $20,000–$50,000. There is 1 high-severity known issue you need to know before handing over a check.

Kestrel Take

The car that proved Japan could build a desirable sports car, and now a genuine blue-chip classic. The L24 straight-six is robust and tunable. The catch is rust — 240Zs dissolve, and rust repair on one is expensive, specialized work that decides the entire purchase.

What we checked

Checked against public records, 2026-09-25

Federal complaint records thin out badly before about 2000, so there is little here to check against. What follows is our own write-up. Treat a short list as us having less to go on, not as the vehicle having fewer faults.

Known Issues for the 1972 Datsun 240Z

Ranked by wallet impact. These are documented, recurring problems — not freak accidents. How we decide that.

Pervasive rust — floors, frame rails, dogleg, battery trayHigh — wallet impact

The 240Z is legendary for rust: floors, frame rails, rockers, the doglegs, the battery tray, and the rear hatch area all rot, often hidden. Structural rust repair is expensive and rust-free cars command huge premiums.

Repair cost (estimate): $4,000-$20,000 — around 57% of what this car is typically worth

Worn or swapped L-series engine and SU carbsMedium
