Key Takeaways
- Mileage stars (★ ★★ ★★★) indicate doubt about the recorded mileage — never ignore them
- ★★★ means the inspector strongly suspects odometer rollback or mechanical replacement
- Repaint marks (W codes) on the damage diagram show which panels were resprayed
- Replaced panels are marked X or XX on the diagram — common after accident repair
- Cross-reference auction photos with damage codes to verify repair quality
Three things on a Japanese auction sheet cause more confusion than anything else — and all three are regularly exploited by sellers who know buyers won't understand them. Mileage stars that warn of odometer fraud, W marks that reveal previous repairs, and P marks that show repainted panels are all clearly visible on every auction sheet. This guide explains exactly what each symbol means, how Japanese inspectors detect the issues behind them, and what to do when you find them.
Mileage Stars — The Inspector's Fraud Warning
The mileage field on a Japanese auction sheet does not just show a number — it also shows the inspector's level of confidence in that number. When the inspector examines a vehicle and suspects the odometer reading does not match the actual wear on the car, they mark one, two or three stars (★) next to the mileage figure.
★★ and ★★★ are critical red flags: These marks come from a trained professional who physically examined the car and believed the odometer had been tampered with. A seller telling you "the mileage is fine, ignore the stars" has a direct financial motive. The inspector did not.
How Inspectors Detect Odometer Fraud
Japanese auction inspectors are specifically trained to cross-reference the claimed mileage against physical wear indicators. A vehicle's true use is recorded in its wear patterns in ways that cannot be erased when an odometer is wound back.
How it works together: A single worn indicator might have an innocent explanation. Two or three worn indicators on the same car at a claimed low mileage is when an experienced inspector marks ★★ or ★★★. They are not guessing — they are pattern-matching multiple data points.
W Marks — Reading Repair History
W marks on the damage diagram indicate that repair work was completed on that panel before the auction. The number after W indicates severity:
| Mark | Meaning | Typical Repair | Concern Level |
|---|---|---|---|
| W1 | Minor repair completed | Small dent removal, stone chip touch-up, minor scratch repair | Low — normal on any used car |
| W2 | Moderate repair completed | Panel beating, bumper repair, door ding removal with filler | Medium — acceptable on non-structural |
| W3 | Significant repair completed | Major panel work, section replacement, extensive filler use | High — check panel location carefully |
The W mark severity alone does not tell the full story — location is equally important. The same W2 mark means completely different things depending on where it appears on the damage diagram:
P Marks — Paint and Repainting
P marks on a Japanese auction sheet indicate paint issues noted by the inspector. Understanding P marks helps you identify repainted panels — which are cosmetically significant and can indicate concealed damage:
| Mark | Meaning | What It Indicates |
|---|---|---|
| P | Paint issue noted | Some form of paint problem — may be partial respray, colour mismatch, or paint defect |
| P1 | Minor paint issue | Small area repainted, stone chip touched up, or minor colour variation |
| P2 | Moderate paint issue | Panel section resprayed or notable colour mismatch |
| P3 | Significant paint issue | Full panel respray, extensive paint correction, or significant colour mismatch |
| W + P | Repaired and repainted | Panel was damaged, repaired with body filler or metal work, then painted — most significant combination |
What Repainting Actually Means
A repainted panel is not just an aesthetic issue. It tells you a story about the car's history:
- A panel was damaged enough to require repainting — this can range from a deep scratch to a replaced panel after a collision. The W mark alongside tells you which.
- The original factory paint is gone — factory paint is baked on at high temperature and is more durable than aftermarket paint. Resprayed panels fade at a different rate from surrounding factory paint over time.
- Filler quality varies — body filler used in repair can shrink, crack or bubble after several years, particularly in hot climates like UAE, Pakistan and Kenya. A repair that looks perfect at auction in Japan may show cracking 2–3 years later in a hot destination market.
- Paint overspray on trim — poorly executed resprays leave paint on rubber seals, window trim and adjacent panel edges. These are visible in detailed auction photos and indicate lower quality repair work.
Hot climate buyers: Body filler expands and contracts with temperature. In climates like Pakistan, UAE and Kenya — with summer temperatures exceeding 40°C — repair filler that seemed fine in Japan can crack within 2–3 years. A W+P mark on a bonnet or wing in these markets is worth factoring into long-term maintenance cost.
Reading Combinations — What Patterns Mean
The most skilled reading of an auction sheet comes from looking at combinations of marks rather than individual symbols:
Why Translation is Essential for W and P Marks
The W and P marks on the damage diagram show where work was done and approximately how much. What they cannot show is the detailed description in the inspector's notes section — which is always written in Japanese.
Inspector notes for repair and paint work often include:
- The specific technique used — panel beating, filler, panel replacement
- Whether the repair is visible from a specific angle or in certain lighting
- Notes on colour match quality — "slight colour variation" or "good match"
- Whether the paint appears factory or aftermarket
- The inspector's overall assessment of repair quality
Without translation, you see the location and severity number — but not the inspector's qualitative assessment. For any car with W2 or W3 marks, or P marks across multiple panels, an English translation of the notes gives you the complete picture.
The $10 rule: A $10 Report + Translation bundle (or $15 Deeper Scan) on a car with multiple W or P marks can tell you whether the repairs were "professional finish, good colour match" or "visible overspray, slight panel mismatch" — a difference worth far more than $10 in negotiating position.
How These Marks Affect Price
Understanding the price impact of each mark type helps you negotiate correctly:
| Mark Scenario | Price Impact vs Clean Car | Notes |
|---|---|---|
| Single W1 on rear bumper, Grade 4.5 | −3% to −5% | Very common, minimal impact |
| W2 on front bumper, Grade 4 | −8% to −12% | Minor front impact disclosed |
| W2 + P2 on front wing, Grade 4 | −12% to −18% | Repaired and repainted non-structural |
| W3 on rear quarter, Grade 3.5 | −20% to −30% | Significant repair, check adjacent panels |
| Multiple W marks, front zone | −25% to −40% | Price as R grade regardless of designation |
| ★★ mileage + W marks | −35% to −50% | Two separate major concerns combined |
| W3 on A/B-pillar | −40% to −60% | Structural work — independent inspection required |
