Decoding Auction Sheet Codes: A Buyer’s Guide to Understanding Used Car Conditions

When looking to buy a used car, particularly from an auction, understanding the auction sheet codes or condition report is crucial. Auction houses use a system of codes to describe the car’s condition quickly and uniformly. Here’s a simple guide to deciphering these codes, helping you make informed decisions.

Decoding Auction Sheet Codes:

Here is we make a list of the complete auction sheet codes:


  • A1: A small scratch, hardly noticeable.
  • A2: A standard scratch, something you might expect on a used car.
  • A3: A big scratch, clearly visible and possibly needing repair.


  • E1: Few dimples, and minor imperfections on the car’s surface.
  • E2: Several dimples, more noticeable but still minor.
  • E3: Many dimples, indicating the car’s surface has multiple small indentations.


  • U1: A small dent, not very noticeable.
  • U2: A standard dent, something that doesn’t affect the car’s operation but is visible.
  • U3: A big dent, likely needing professional repair to restore the car’s shape.

Repair Marks/Waves

  • W1: Negligible repair mark/wave, indicating very minor previous repair work.
  • W2: Repair mark/wave, showing evidence of repair that might be noticeable upon close inspection.
  • W3: Obvious repair mark/wave, clear signs of significant repair work.

Rust and Corrosion

  • S1: Rust, indicating the start of metal degradation.
  • S2: Heavy rust, a more serious metal deterioration that will need addressing.
  • C1: Corrosion, similar to rust but might involve different materials or more severe metal eating.
  • C2: Heavy corrosion, indicating a significant issue that could affect the car’s integrity.

Paint and Bodywork

  • P: Paint marked, showing signs of paintwork that doesn’t match or is marked.
  • H: Paint faded, indicating the paint has aged or been damaged by sunlight.
  • X: Needs to be replaced, suggesting a part of the car requires replacement due to damage or wear.
  • XX: Replaced, parts of the car have been replaced, which could be due to damage or upgrading.

Glass and Windshield

  • X1: Small crack on the windshield, minor but might need attention.
  • B1-B3: These codes combine dents and scratches, ranging from small (B1) to big combinations of both (B3).
  • Y1-Y3: Indicates the size of holes or cracks, from small (Y1) to big (Y3).
  • R: Repaired crack on the windshield, has been fixed but is worth noting.
  • RX: The repaired windshield needs replacement, suggesting the repair might not hold long-term.
  • G: Stone chip in glass, small but could lead to bigger cracks if not addressed.

Understanding these auction sheet codes can help you assess the condition of a car before purchasing at an auction. It’s a quick way to get a sense of the vehicle’s exterior condition, which can be crucial for making a decision. Remember, while some issues are purely cosmetic, others might indicate more serious problems.
