Custom Vehicle Valuation

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.

Vehicles and modifications

Assignments may involve performance, appearance, utility or accessibility changes.

  • Performance and powertrain builds
  • Suspension, wheels and braking upgrades
  • Custom paint and bodywork
  • Off-road and overland builds
  • Work bodies and commercial equipment
  • Accessibility and specialized-use conversions

Documentation reviewed

Reliable records help distinguish a documented build from unverified owner claims.

  • Component invoices
  • Installer records
  • Build photographs
  • Dyno or specification information where relevant
  • Maintenance and safety records
  • Current condition photographs

Market analysis

The appraisal may use multiple approaches when exact modified comparables are limited.

  • Base vehicle market
  • Modified comparable vehicles
  • Component contribution
  • Quality and integration
  • Buyer-market breadth
  • Depreciation and obsolescence

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.
