Buyer Checklist
⚠ Clone warning: Numbers-matching adds 30-40% premium. Always verify with cowl tag, engine stamp, and registry before purchase.
Check frame rails from underneath — number one failure point
Inspect all floor pans and sills
Check rear hatch seal area for rust
Verify fuel injection system operation — common failure
Check for engine swaps (L28 is correct)
Inspect strut towers for cracking
Check nose area for accident damage
Verify 2+2 if listed as such — longer body easy to verify
Road test fuel injection — rough idle indicates problems
Check for oil leaks around cam cover and oil pan
Known Problem Areas
Frame rail rust — same as 240Z
Fuel injection system failures — Bosch components expensive
Floor pan and rocker panel rust
