Resto-Mod & Pro-Street Appraisals
What Is a Resto-Mod or Pro-Street Appraisal?
A resto-mod or pro-street appraisal is a professional valuation of a classic or specialty vehicle that has been significantly modified from its original configuration.
A resto-mod typically combines the appearance and character of a classic vehicle with modern performance, handling, comfort, safety, or technology.
A pro-street vehicle is generally built with a stronger emphasis on high-performance components, aggressive styling, drivetrain modifications, chassis work, and other performance-oriented upgrades.
Because these vehicles can vary dramatically from one build to another, their value cannot be determined by simply looking up the year, make, and model.
A certified appraisal evaluates the actual vehicle, the work performed, the components used, the quality and condition of the build, supporting documentation, and relevant market data.
When Do You Need a Resto-Mod or Pro-Street Appraisal?
You may need an appraisal if:
-
You need agreed value insurance coverage
-
You recently completed a major build or restoration
-
You added significant performance or custom upgrades
-
You are buying or selling the vehicle
-
You need documentation to support an asking price
-
You need value documentation for financing
-
The vehicle is part of an estate, probate, divorce, or bankruptcy matter
-
The vehicle was damaged or declared a total loss
-
You want a professional record of the build and its current value
-
Your existing appraisal no longer reflects the vehicle
A professional appraisal is especially useful when the vehicle represents a substantial investment in parts, fabrication, restoration, and labor that cannot be accurately reflected by a stock vehicle pricing guide.
Why Resto-Mods and Pro-Street Vehicles Are Different to Value
Two resto-mods built from the same year, make, and model can have dramatically different values.
One may have a mostly stock body with a modern crate engine and upgraded brakes. Another may include a custom chassis, hand-fabricated bodywork, high-end suspension, a completely redesigned interior, extensive electronics, and a professionally built drivetrain.
The original vehicle matters—but so does everything that happened after it left the factory.

Parts Cost Is Not the Same as Market Value
Building a resto-mod or pro-street vehicle can require a significant investment. Owners may have extensive receipts for engines, transmissions, suspension systems, wheels, paint, interiors, fabrication, and professional labor.
Those records are extremely helpful, but the amount invested in a vehicle and its current market value are not automatically the same.
An appraisal considers the cost and quality of the build alongside condition, execution, desirability, market demand, comparable vehicles when available, and other factors that influence what the completed vehicle may be worth.
This provides a more supportable valuation than simply adding up receipts.
Resto-Mod & Pro-Street Appraisals for Buying or Selling
Modified vehicles can be difficult for buyers and sellers to price because there may be few truly comparable vehicles available.
A certified appraisal provides an independent opinion of value based on the actual vehicle, its build, condition, documentation, and relevant market information.
For sellers, this can help support an asking price.
For buyers, it can provide additional information before committing to a high-value specialty vehicle purchase.
How a Resto-Mod or Pro-Street Appraisal Helps
Your certified appraisal helps support:
- Agreed-value insurance
- Insurance policy updates
- Private sales
- Purchase decisions
- Financing or loan review
- Estate and probate matters
- Insurance claim discussions
- Ownership records
- Documentation after major modifications

Instead of relying on a standard value guide, you receive a professional report documenting the vehicle, its build, and the factors supporting its value.
-
Step 1
We Confirm the Appraisal Purpose
We begin by confirming why you need the appraisal and how the report may be used. Insurance, resale, financing, legal, ownership, and claim-related appraisals may require different documentation.
-
Step 2
We Inspect and Document the Vehicle
Your local appraiser meets at the vehicle's location when possible to inspect and document the build.
We take detailed photographs, verify identifying information, document overall condition, and record the components and modifications that may affect value.
This may include the engine, drivetrain, chassis, suspension, brakes, bodywork, paint, interior, performance components, fabrication, specialty equipment, restoration work, and other unique features.
-
Step 3
Our Research Team Reviews Market Data and Comps
After the inspection, the photos and documentation are reviewed by our research team.
They evaluate relevant market information, comparable vehicles when available, historical valuation data, enthusiast-market activity, build quality, and other factors appropriate to the vehicle.
-
Step 4
You Receive a Certified Appraisal Report
Once complete, you receive a certified appraisal report documenting the vehicle, build, appraisal purpose, research, and professional opinion of value.
The report can be used for insurance, buying or selling, financing, ownership documentation, estate planning, legal matters, or other valuation needs.
What Makes an Auto Appraisal Network Report Different?
A resto-mod or pro-street vehicle cannot be accurately represented by a year-make-model lookup.
Auto Appraisal Network reports combine hands-on vehicle documentation, detailed photography, professional market research, comparable sales information when available, and a clear valuation summary.
Your local appraiser documents the vehicle as it actually exists—including the components, craftsmanship, modifications, restoration work, and its condition that distinguish it from a stock vehicle.
The result is a certified appraisal report designed to clearly document what has been built and provide a supportable professional opinion of value.
Resto-Mod & Pro-Street Appraisals FAQs
What is a resto-mod?
A resto-mod is generally a classic vehicle that retains much of its original appearance or character while incorporating modern performance, handling, braking, comfort, safety, or technology upgrades.
What is a pro-street car?
A pro-street car is typically a heavily modified performance-oriented vehicle that combines street-car styling with significant engine, drivetrain, chassis, suspension, wheel, tire, or fabrication work. Builds vary widely, which is why individual documentation is important.
Why can't I use a standard classic car value guide?
Standard guides generally value vehicles according to relatively standard configurations and condition levels. They may not adequately account for a modern drivetrain, custom chassis, fabrication, upgraded suspension, specialty paint, custom interior, or other major modifications.
Does an appraisal include the money I spent building the vehicle?
Receipts for parts and labor can be important supporting documentation, but build cost and market value are not necessarily the same. The appraisal considers the investment along with build quality, condition, desirability, market demand, and comparable vehicles when available.
Can a resto-mod appraisal be used for agreed value insurance?
Yes. Certified appraisals are commonly used to help document modified and specialty vehicle values for agreed value insurance. Insurance requirements vary by company and policy.
Should I update my appraisal after major modifications?
Yes. If you change the engine, drivetrain, suspension, paint, interior, chassis, or other significant components, your previous appraisal may no longer represent the current vehicle.
Can you appraise a vehicle built by a professional custom shop?
Yes. Documentation identifying the builder, components, build history, receipts, photographs, awards, and other records may be useful during the appraisal.
Can you appraise a home-built resto-mod or pro-street vehicle?
Yes. Professionally built and owner-built vehicles can both be appraised. The appraiser evaluates the actual vehicle, its components, workmanship, condition, documentation, and relevant market information.
Who performs the appraisal?
Your appraisal is handled by the local Auto Appraisal Network appraiser or franchise owner serving your area, with the appraisal prepared through AAN's certified report process.
