How to Read a Korean Auction Sheet: Grading Systems Explained

Read the grade and the panel diagram together

Auction grades summarize only part of an inspection. Grade A is not a guarantee of no accidents, no structural damage or completed repairs. A report can show structural findings without changing its accident grade. Check the original diagram, inspection notes and present repair needs before bidding.

Accident and exterior/condition ratings are separate. Glovis and K Car display a letter with a numeric score; SK, AJ and Lotte display two letters. For numeric scores, 9 is best and 1 is worst. The same letter does not necessarily mean the same thing at different houses.

House-specific meanings

HouseHow to read the accident grade
GlovisA means no major frame replacement history under its criteria. It does not rule out other damage or work. Read the original report for the affected structural parts.
SKThe accident grade counts replacement history, not panel work. A means no replacement history under SK criteria; W findings can still be present.
AJ / KolonCurrent A means no structural-panel replacement history. Structural W and exterior-panel replacement do not change that grade.
LotteA means no structural-panel replacement history. Panel work and painting do not count toward the accident grade.
K CarApply K Car’s own criteria. We have not verified its detailed current A–F thresholds against an official grading table; do not substitute another house’s definitions.

For example, Glovis A/7 combines no major frame replacement history with a good condition score. It does not establish structural safety. A/1 has the same accident letter but a very poor condition score. Neither is automatically a better purchase than B/7: compare the actual findings and repair needs.

A 2021 Audi A5 at AJ’s September 22, 2026 auction had A/A with W on four structural panels and XX on four exterior panels. That is compatible with AJ’s rules, not proof of an incorrect grade or a damage-free structure. W can include deformation still needing repair.

Damage codes depend on the house and report version

SourceCodeMeaning
SKXXPrevious replacement
SKX / Q / PReplacement / panel work / paint needed now
SKWPanel work / welding / bending; not proof of completed repair
Current AJXX / PReplacement history / paint history
Current AJWPanel work / welding / bending, including possible existing deformation
Current AJX / RReplacement / repair needed
Legacy AJXReplacement history
Legacy AJU / E / FPanel work and paint needed / replacement needed / bent or warped
LotteXX / X / QReplacement history / replacement needed / panel work and paint needed
K CarX / WReplacement / panel work findings in the original report

The legacy AJ legend is visible on the original Korean sheet reproduced on page 2 of the 2024 BE FORWARD guide. Do not apply legacy X to the current-condition X slot on newer AJ reports.

A missing mark is not proof of an undamaged panel: the source may omit a panel or an inspection category. A repair-history mark does not certify repair quality. Structural parts such as pillars, side sills, rear quarter panels, wheelhouses and side members require close review; their exact classification depends on the house. Do not infer the cause or severity of a collision from a single mark.

Mechanical findings are separate

Look for 수리요 / 정비요 (repair or service needed), 교환요 (replacement needed), 누유 (oil leak) and 부식 (corrosion). A high grade does not cancel these findings. Flood, fire and total-loss disclosures must be checked separately; the letter alone does not identify them.

Use the auction grading guide for each house’s tables and legends. Primary references include SK inspection criteria, AJ / Kolon’s guide, and Lotte’s inspection scoring criteria. The current AJ explanation follows guide ver.1 issued August 4, 2026.
