Which document is essential for determining a vehicle’s repair costs?

The essential document for determining a vehicle's repair costs is the repair estimate or invoice from an authorized repair facility. This document provides a detailed breakdown of the costs associated with the necessary repairs, including parts, labor, and any additional services required to restore the vehicle to its pre-damage condition.

A repair estimate is typically generated by qualified automotive technicians who assess the vehicle's damage and identify all the required repairs and associated costs. This makes it the most reliable source of information for appraisers, insurers, and vehicle owners when evaluating the financial implications of the repairs.

The other documents listed can provide useful information but do not specifically outline the costs of repairing the vehicle. The vehicle's title certificate mainly proves ownership and does not contain repair cost details. The initial purchase agreement may provide insight into the vehicle's original price but does not reflect current repair needs or costs. Similarly, the vehicle registration document confirms the vehicle's legal status but does not provide any financial insights regarding its repair.
