When should an auto appraiser consider replacement of a damaged part?

An auto appraiser should consider the replacement of a damaged part when the repair cost exceeds 75% of the part's cost because it provides a threshold beyond which replacement is often more economical and practical than repairing. When repair costs reach such a high percentage of the part's original value, it typically indicates that the part has sustained significant damage and may not be restored to its original function or condition.

Choosing to replace rather than repair at this point helps ensure that the vehicle is restored to a safe and reliable state. Additionally, replacement can often guarantee a better long-term outcome regarding the vehicle's performance and resale value. Repairing parts that are significantly damaged might lead to ongoing issues, which could ultimately cost more in future repairs. This threshold aids appraisers in making cost-effective and informed decisions about vehicle restoration.
