Buyer Checklist
⚠ Clone warning: 409 non-matching loses 50%+. Always verify with cowl tag, engine stamp, and registry before purchase.
Verify SS package via cowl tag — not all Impalas are SS
Check engine suffix code for 409 verification
Inspect body for rust — full-size B-body has many rust-prone areas
Check floor pans, trunk floor, and frame rails
Verify correct bucket seats and console if SS
Look for build sheet under rear seat
Inspect for lowrider modifications — very common on this model
Check for correct SS badging and trim pieces
Verify 409 cars have correct dual exhaust
Road test: check for rear axle noise
Known Problem Areas
Floor pan and trunk rust — very common
Frame rail corrosion
Lowrider modifications — hydraulics, custom suspension
Clone SS — non-SS cars converted
409 engine replacements — verify numbers
