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 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 1

  • 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 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 3

  • Up to 4 medium bodyshop repairs
  • Could require a new bumper but not 2
  • Up to 3 major bodyshop repairs

Grade 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 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 panelScratch 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.
