Modified and Custom Vehicle Appraisals Across Canada
Modified vehicles cannot be valued by adding every invoice to the base vehicle. The appraisal separates the underlying vehicle, installed components, workmanship, usability, market demand and the extent to which the modifications are recognized by buyers.
What matters: Modification cost and market contribution are different. Some changes add desirability, some narrow the buyer pool and others may have little recoverable value.

Frequently asked questions
Are modification invoices added in full?
No. Invoices prove cost and scope, but market contribution depends on condition, demand, transferability and quality.
Can an insurer use the appraisal for coverage?
The insurer decides its documentation and underwriting requirements. Confirm those requirements before ordering.
Do you appraise unfinished projects?
Possibly, but the report scope and value basis must reflect incomplete condition and limited market evidence.
Provide the base vehicle and modification list. Invoices, build photos and current condition images are especially helpful.
