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
No public record to reconcile against
We don't yet have a public record to check this one against. Federal complaint records thin out badly on older vehicles, so there is little to check against. What follows is our own write-up, and it has not been reconciled against an official record. Treat it as a starting point, not a verdict.
Known Issues for the 1972 Datsun 240Z
Ranked by wallet impact. These are documented, recurring problems — not freak accidents.
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

The engine is durable but the SU carburetors need knowledgeable tuning and many cars have been swapped or modified.
Repair cost (estimate): $500-$3,000
Source: not yet checked against public records.
Correct interior, trim, and bumper parts for early cars are scarce and expensive.
