What is Auction Grading?

The aim of the NAMA grading scheme at its highest level is to deliver key benefits to all the parties involved in the transaction.  It is designed to facilitate the buying and selling process of a used car in a condition that is better understood by both parties.  With a better understanding of a vehicle condition it should be possible to more accurately anticipate a selling price that is consistent with the typically observed prices for similar cars in the same trading period, subject to similar market conditions.
The Grades
The scheme consists of 5 grades, termed wither A to E or 1 to 5.  There is also an unclassified grade for vehicles that are badly accident damaged or require high levels of repair.  Also auctions and vendors may choose to give certain cars an unclassified grade probably if they are very high mileage or old.
Grade Bandings
Grade A/1
a combination of the following:
  • Minor repairs, for example, small dent without paint damage or touch in type repair
  • Missing minor trim items, e.g. tow eye cover
  • Any panels which require paint
Grade B/2
  • 1 medium bodyshop repair or a combination of 1 medium bodyshop repair and several minor repairs
  • May have up to 7 minor repairs or a combination of minor repairs and small missing components
  • Any vehicle with more than 1 medium bodyshop repair
Grade C/3
  • Up to 4 medium bodyshop repairs
  • Could require a new bumper but not 2
  • Up to 3 major bodyshop repairs
Grade D/4
  • A single major repair and some medium and/or minor repairs
  • Major repairs to structural components; example roof of quarter repair
  • More than 1 major repair
Grade E/5
  • More than 2 major repairs
  • More than 5 major repairs
  • More than 2 structural repairs or 2 with any other damage
  • Combination of all the above up to a total of 3500 points
  • Vehicles in this grade are simply uneconomical to appraise and fall into one of the following categories
Substantial accident damage
  • Major parts missing
  • Multiple recorded items exceeding the criteria of Grade 5
  • Multiple unrecorded items
Note:  The use of ‘U’ grade limits the amount of damage that can be recorded against a grade 5 vehicle and keeps the band tighter.
Component/Damage Severity Scores
An appraiser should be proficient in recording objectively the damage/severity of component.  However, it is likely to be the method of repair that will actually determine the effect of the item of damage on the overall value of the vehicle – this would need to be determined by an appropriately qualified individual.
An anticipated repair methodology has been used to allocate by the panel of ‘experts’ as follows:
Dent to Panels
Severity: Repair Method:
2 or less up to 10mm Smart repair
Over 2 up to 10mm Smart repair
Between 10mm and 30mm Smart repair
With paint damage Repair and refinish
Between 30mm and 100mm Repair and refinish
Over 100mm Repair and refinish
Over 30% of panel
Scratch to Panels
Severity: Repair Method:
Up to 25mm not through paint Machine polish
Over 25mm not through paint Machine polish
Up to 25mm through paint Smart repair
Between 25 and 100mm through paint Refinish
Over 100mm through paint Refinish
Rusted Refinish
The above is to be used for scoring only and should not be used as an indication of the actual repair requirements.
Information Only – 0 Points
Some information will be included on the appraisal that will relate to items that do not warrant a score such as light scratching which will normally polish out or to replacement parts (e.g. exhausts) that do not form part of the evaluation of cosmetic condition report.
