How do appraisers verify vehicle modifications during inspections?

Appraisers verify vehicle modifications during inspections primarily by checking against manufacturer specifications. This method ensures that modifications adhere to safety standards and manufacturer guidelines, thereby maintaining the vehicle's integrity and resale value. By referencing official specifications, appraisers can accurately determine if the modifications are legitimate and properly executed, and assess their impact on the vehicle's overall value.

Relying solely on visual changes may lead to misinterpretations, as not all modifications are immediately apparent or can be properly assessed just through observation. An owner’s statement may not always provide accurate or complete information regarding modifications, which could affect the appraisal's reliability. Estimating the cost of changes does not confirm their validity or adherence to safety standards; it merely provides a financial aspect without verifying the specifics of the modifications themselves. Thus, consulting manufacturer specifications is the most reliable approach for appraisers to ensure an accurate assessment of vehicle modifications.
