How we calculate the Build Score

The system computes a technical score based on the modifications declared in the listing.

• Each modification has a base weight.
• Some categories apply multipliers or balancing caps.
• Coherent packs (for example suspension, brakes, cooling) receive extra bonuses.
• The final total is converted into stars from 0.5 to 5.0.

The Build Score describes the structure and coherence of the declared build. It does not replace technical verification or an in-person appraisal, and does not indicate the vehicle's mechanical condition or maintenance status.
