Which term describes the actions taken to remove or replace parts in vehicle appraisal?

The term that best describes the actions taken to remove or replace parts in vehicle appraisal is "overhaul." An overhaul is a comprehensive process in which a vehicle's components are inspected, repaired, or replaced as necessary to restore it to optimal condition. This typically involves disassembling certain parts of the vehicle, assessing their condition, and then executing repairs or replacements to ensure functionality and safety.

In contrast, the other terms have different meanings in the context of vehicle appraisal. "Assessment" refers to the evaluation or analysis of the vehicle's condition and value but does not imply specific actions taken regarding repairs or replacements. "Estimation" involves determining the cost of repairs or the value of the vehicle but is typically focused on financial figures rather than physical actions. "Valuation" is the process of determining the monetary worth of the vehicle based on various factors, but it does not involve direct action on the vehicle itself. Therefore, "overhaul" is the most appropriate term to describe the physical actions involved in repairing or replacing vehicle parts during the appraisal process.
