Improvements to our valuations.

Great news! We are improving our valuations delivered in your VRM Valuation API.



What’s changing?

As part of the ongoing improvements to our vehicle valuation methodology, we are introducing important changes to the AutovistaValuation API. These updates, launching in October 2025 are designed to deliver even greater insights into current market conditions, ensuring you’re fully prepared for the transition.

After October 2025, we will be moving away from providing separate Calculation Modes including Grade, Condition & Sector specific values, Average Mileage, Mileage adjustments and Basic values but continue provide a Standard Trade & Retail Value.

Key changes:

1. Legacy Calculation Modes 

After October 2025, certain calculation modes – such as Grade, Condition & Sector specific values, will no longer be supported. These modes were originally designed to address specific use cases, such as condition-based or industry-specific valuations, but are being replaced to better align with a more dynamic and market-responsive methodology.

If you are currently using these values you will need to adapt your systems to utilise Standard calculation modes for Retail & Trade values.  

2. Average Mileage

Mileage corrections are already incorporated into Glass’s Trade and Retail values, driven by real-time market data. From October 2025, an average mileage parameter will no longer be included in the API response. If your business requires this data, we recommend sourcing average mileage figures from an external, market-reliable provider. However, please note that relying on average mileage alone may not fully capture market dynamics, as our updated methodology incorporates a broader range of variables to deliver more comprehensive valuations. 

3. Basic Residual Value / Mileage Correction

As average mileage parameter will no longer be available, this means there will no longer be Basic Residual Values or Mileage corrections returned within the API.  This change reflects our move to a more dynamic valuation approach, where mileage corrections are fully integrated into Glass’s Trade and Retail values rather than applied separately. 

As a result, there will no longer be a standalone basic valuation based on assumed average mileage and condition. Instead, all valuations will reflect real-time market data, ensuring a more accurate representation of vehicle value.

FAQs

Currently, legacy calculation modes (e.g., Grade Low, Average, High, and others highlighted in grey in the table) provide useful references for valuing vehicles based on condition, cosmetic needs, or specific industry use. These modes will no longer be supported after October 2025 as part of our transition to a more dynamic valuation methodology.
From this date, only Standard Trade and Retail valuations will be available via the API. Requests for discontinued modes will return either a ‘0’ value or an error message stating ‘calculation mode no longer supported.’
To ensure a seamless transition, customers must update their systems to use the Standard calculation mode. For vehicles previously classified under legacy modes, you can:
  1.  Adjust Standard Trade or Retail values: Apply value-increasing or decreasing factors using your internal pricing logic to account for vehicle condition, repair needs, or other specific considerations.
  2.  Leverage Repair Estimate insights: Repair Estimate can help assess the costs of cosmetic, trim, and Bodyshop repairs, providing a robust foundation for refining valuations. This ensures your pricing stays aligned with market trends and reflects a vehicle’s specific condition. If you’re interested in this feature, please contact our Sales Team.
By transitioning to the Standard calculation mode and incorporating these tools, you can maintain accurate, competitive, and market-relevant valuations even as legacy modes are phased out.
As part of our transition to a more dynamic valuation methodology, certain legacy calculation modes, including Grade Low, Average, High, and others highlighted in grey in the table, will no longer be supported after October 2025. These calculation modes, which were previously useful for valuing vehicles based on condition, cosmetic needs, or specific industry use, will be discontinued.
From this point, only Standard Trade and Retail valuations will be available through the API. Requests for the discontinued modes will return either a ‘0’ value or an error message stating, “calculation mode no longer supported.”
Additionally, as average mileage will no longer be available, the API will no longer provide a basic value using an average mileage. Specifically, BasicResidualValue and AverageMileage will return a ‘0’ value after the launch in October 2025.
Mileage corrections will now be directly incorporated into Glass’s Trade and Retail values, removing the need for a fixed “standard mileage.” Adjustments will instead be based on real-time market observations, providing a more accurate and up-to-date reflection of vehicle values.
This new, AI-driven approach, supported by our expert editor team, offers a comprehensive, data-driven view of the market, reflecting real-world pricing trends and empowering you to make more confident, informed decisions.

If you have identified that you are using calculation modes that will no longer be supported, our Integration Team is available to assist with any technical queries you may have. Additionally, detailed technical support documentation for APIs is available to help guide you through any changes.
