Modified & Specialty Vehicle Documentation Worksheet
This worksheet helps owners and industry professionals organize modifications and supporting documentation before a professional appraisal. It is designed for modified vehicles, performance vehicles, classic vehicles, restored vehicles, specialty vehicles, custom builds, and collector vehicles.
Modified and Specialty Vehicle Appraisal
Appraising a modified or specialty vehicle requires a different approach than appraising a standard production vehicle. The relevant market evidence, the significance of modifications, and the documentation available all affect the appraisal process.
This worksheet helps organize the vehicle information and modification documentation that a professional appraiser may consider. Organizing this information before an appraisal can help ensure that relevant evidence is available and clearly documented.
The worksheet calculates simple totals for documented parts cost, labor cost, and total documented expenditure. These totals are organizational summaries only — they are not appraisal conclusions and do not represent the market value contribution of the modifications.
Documented Cost Is Not the Same as Market Value Contribution
The amount spent modifying or restoring a vehicle does not automatically increase its market value by the same amount. Market contribution may vary depending on the vehicle, the modification, quality, desirability, installation, condition, documentation, buyer market, originality, reversibility, and broader market evidence.
This worksheet documents evidence. It does not determine the market contribution of modifications. A professional appraisal considers the available market evidence for the specific vehicle and its modifications — not a formula based on expenditure.
Some modifications may increase market value. Others may have limited or no market value contribution. Some modifications may affect value in ways that depend heavily on the buyer market and the specific vehicle. A professional appraiser evaluates these factors based on available market evidence.

Important: Documented cost is not the same as market value contribution. The amount spent modifying or restoring a vehicle does not automatically increase its market value by the same amount. A professional appraisal considers the available market evidence for the specific vehicle and its modifications.
