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.
—
No Star
Mileage accepted as accurate. Inspector found no inconsistency between odometer reading and physical condition.
★
One Star
Minor doubt. Mileage is slightly inconsistent with condition. Not necessarily fraud — may reflect unusual use patterns.
★★
Two Stars
Significant doubt. Inspector suspects the mileage may not be accurate. Treat as a serious red flag requiring independent verification.
★★★
Three Stars
Strong doubt. Inspector believes mileage has likely been altered. Do not proceed without independent mileage verification.
不明
Fumei
Mileage unknown — odometer not functioning or unreadable at time of inspection. Real mileage completely unknown.
0
Zero / Blank
Odometer showing zero or blank. Either non-functional, recently replaced, or deliberately cleared. Same risk as 不明.
★★ 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.
🦶
Brake and Accelerator Pedals
Rubber pedal covers wear in a very consistent pattern with real mileage. Heavy pedal wear on a claimed 50,000km car is immediately suspicious. Replacement rubber pedals are themselves a red flag — why replace them on a low-mileage car?
🪑
Driver's Seat Bolster
The fabric or leather on the driver's seat entry bolster wears from repeated use. After 100,000km the wear is unmistakable. A deeply worn seat bolster on a claimed 60,000km car triggers immediate doubt.
🔄
Steering Wheel Finish
The finish and texture on the steering wheel wears predictably in the 9 o'clock and 3 o'clock grip positions. Deep wear here on a claimed low-mileage car is a clear inconsistency.
🔧
Gear Knob
Manual transmission gear knobs develop a distinctive wear pattern at the top from gear changes. Even automatic selector covers show wear on the frequently-used positions.
📋
Service Record Stamps
Japanese cars often have a service book with dealer stamps showing mileage at each service. If available, inspectors compare these stamps against the odometer reading directly.
🛞
Tyre Wear and Age
Tyre wear and manufacture date (DOT code) can indicate mileage inconsistencies. Brand new tyres on a claimed 30,000km car suggests the originals were worn out and replaced — inconsistent with the stated mileage.
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:
W2 on Bumper
Rear or Front Bumper
Very common — bumpers are the most frequently repaired panels on any Japanese city car. W1 or W2 on a bumper is normal and should not affect your buying decision at the right price. Bumpers are cosmetic components, not structural.
W2 on Door
Side Door Panels
Common from parking lot impacts and door dings. W1 or W2 on doors is acceptable at the right price. A W3 on a door suggests more significant damage — check whether adjacent panels also show marks suggesting the impact was more extensive.
W2 on Bonnet or Boot
Bonnet / Front Wing / Boot
Moderate concern. W2 on a bonnet or front wing suggests a front impact. Check whether the adjacent front wing, bumper and headlamp area also show marks — multiple W marks across the front zone indicate a more serious incident than any individual mark.
W3 on A/B-Pillar
A-Pillar, B-Pillar or Roof
High concern. Structural panels that protect occupants in collisions were damaged and repaired. Straightened and welded structural members may not perform correctly in a future accident. This requires physical structural inspection before purchase — never buy blind on sheet data alone for this location.
Multiple W marks in one zone
3+ W Marks in the Same Area
The most important pattern to recognise. Three W marks across the front left corner — bumper, wing, door — indicates an incident significantly more serious than any individual mark suggests. The car should be priced as R grade even without an R designation.
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:
Normal pattern
A1 rear bumper + A1 door edges + A1 bonnet
Isolated minor marks on different panels from normal use. No W marks, no P marks, no mileage stars. This is a typical well-maintained Grade 4.5 Japanese car — nothing to be concerned about.
Acceptable pattern
W2 rear bumper + A1 door + no stars
Single minor rear impact repaired professionally. Grade 4 or 4.5 with this pattern is fine at the right price. The repair is disclosed, the location is non-structural, and the mileage is accepted. Normal import candidate.
Caution pattern
W2 front bumper + W2 front wing + W1 bonnet
Multiple repairs in the same front zone — indicates a front impact. Even with a Grade 4 headline, this car had a meaningful front impact. Price should reflect R-grade economics even without an R designation.
Red flag pattern
★★ mileage + W marks + Grade 4
Mileage doubt combined with repairs. The inspector suspects the odometer — and there is visible repair work. This combination suggests the car may have had a more significant history than the Grade 4 implies. Walk away or demand full translation plus independent inspection.
Critical pattern
W3 A-pillar + W2 front floor + W2 bonnet
Structural work on A-pillar, plus front floor and bonnet repairs. This car had a serious frontal impact affecting structural members. Even without an RA grade, this vehicle presents structural safety risk that cannot be assessed from an auction sheet alone.
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 English translation 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 |

Frequently Asked Questions
What do mileage stars mean on a Japanese auction sheet?
+
Mileage stars next to the odometer indicate the inspector's confidence in the mileage. No star means accepted as accurate. ★ means minor doubt. ★★ means significant doubt — inspector suspects the mileage may not be accurate. ★★★ means strong doubt — inspector believes mileage has likely been altered. 不明 (fumei) means mileage unknown. Any ★★ or ★★★ rating is a serious red flag.
What does a W mark mean on a Japanese auction sheet?
+
W marks indicate repaired damage — the panel was damaged and repair work was completed before auction. W1 is minor repair, W2 is moderate, W3 is significant. The location matters as much as the number — W2 on a bumper is normal, W3 on an A-pillar is a structural safety concern.
What is a P mark on a Japanese auction sheet?
+
P marks indicate paint issues — partial or full panel respray, colour mismatch, or paint correction noted by the inspector. P1 is minor, P2 is moderate, P3 is significant. W and P marks together in the same location confirm a panel was repaired and repainted.
How do Japanese auction inspectors detect odometer fraud?
+
Inspectors cross-reference claimed mileage against physical wear: brake and accelerator pedal rubber wear, driver seat bolster wear, steering wheel finish wear, gear knob wear, and service record stamps. Multiple wear indicators inconsistent with the claimed mileage result in ★★ or ★★★ mileage doubt marks.
Should I avoid cars with repainted panels?
+
Not necessarily. A single W1 or W2 on a bumper or door at a fair price is perfectly acceptable — minor repairs are common. The concern arises when multiple panels in the same zone are repainted (suggesting a larger incident), when structural panels are involved, or when the seller has not disclosed the repairs. Always factor repair marks into the price.
