Improvements to our valuations in Glass's

Great news! We are improving our valuations in Glass's.

What’s changing?

We’re evolving our proven valuation methodology, bringing market-aligned insights that further support strategic planning. These changes are designed to optimise your products and ensure they continue to deliver the precision and reliability you expect.

Ongoing improvements to our valuation methodology

We’re continuing to evolve our valuation methodology to ensure Glass’s reflects real market activity with the highest possible accuracy.

From 1 December 2025, we’re introducing an additional enhancement to maintain full consistency across our products:
Retail values in Glass’s will now be aligned with retail transacted values, meaning these values reflect what vehicles are actually selling for when live data isn’t available.

Your Live Retail feature remains unchanged, continuing to provide real-time visibility of competitor pricing and market trends.

This change provides more flexibility and precision in an evolving market, ensuring you can continue to rely on Glass’s to support confident, data-driven decisions.

Key Updates implemented earlier this year:

1. Exact Mileage Calculations

We transitioned from average mileage estimates to exact mileage-based valuations, ensuring results are directly aligned with a vehicle’s actual usage for greater precision. As a result, valuations based on average mileage is no longer possible, and average mileage will no longer be visible in the product.

Observed Average Mileage is included in the Ad Search feature within Glass´s Live Retail functionalities, providing valuable insights into the average mileage of vehicles currently on sale.

2. End of Mileage Corrections:

Mileage correction factors were withdrawn, as mileage will now be fully integrated into the core valuation.

3. Phasing out condition grading and alternative valuations:

We no longer use condition grading or alternative valuation methods, as our advanced AI-driven market insights already account for these factors in one dynamic valuation for trade and retail

Why this matters

By combining the Common Valuation Methodology with the new retail transacted value alignment, all valuations within Glass’s are now based on consistent, verified market data.
This means:

More reliable, real-world valuations to support confident pricing and forecasting decisions.
Greater transparency between trade, retail, and live data sources.
A unified, group-wide approach across all Autovista products.

What’s next? 

No action is required – these updates will apply automatically.

We’ll continue refining our data and methodology to provide the clearest picture of the real retail market.

FAQs

Trade valuations will continue to be based on robust market data and refined to provide accurate and reliable insights. This ensures dealers and traders have a dependable foundation for assessing vehicle values and making informed pricing decisions in today’s dynamic market.

Mileage corrections are now directly incorporated into Glass’s Trade and Retail values, making them fully data-driven. Instead of relying on fixed values for mileage corrections, adjustments are based on real-time market observations.

As a result, there will no longer be a fixed “standard mileage,” and a value based on an average mileage will not be provided separately. Powered by an AI-driven system and supported by our expert editor team, this approach delivers a reliable, comprehensive view of the market, reflecting real-world pricing trends and supporting confident decision-making.

In the future, there will no longer be a fixed “standard mileage,” and it will no longer be displayed separately. Mileage corrections are now directly incorporated into Glass’s Trade and Retail values. Instead of using fixed values for mileage corrections, adjustments are based on real-time market observations.

If you wish to obtain a quick valuation, we recommend using an external, market-reliable source for average mileage. However, within our Live Retail data, we provide an observed average mileage powered by data-driven insights of vehicles currently on the market. Unlike static figures, this observed mileage dynamically reflects the latest market trends.

Please note that relying solely on average mileage may not provide the most accurate reflection of current market conditions, as our new approach factors in a broader range of variables to align valuations with real-world behaviour.

We are committed to keeping you informed as we roll out these improvements. You will receive regular updates about specific product changes, ensuring you’re always up to date on key adjustments and new features. These updates will be sent to you over the course of the next several months, with the goal of aligning the changes by December 2025. Rest assured, we’ll provide timely information on how these updates will impact your usage and experience with the product.

We plan to go live with these changes progressively over the coming months, with all updates fully implemented by December 2025. A scheduled maintenance weekend (28–30 November, to be confirmed) will support this transition. As we move forward, we’ll keep you informed with regular updates about the specific timelines for each stage of the rollout, so you can stay ahead of any changes affecting your product experience.
