Brego vs Glass’s Guide – Accuracy

At Brego, we pride ourselves on being the most accurate vehicle valuations and analytics company in the UK. Our advanced technology and deep-learning neural networks process billions more data points than any traditional provider can, allowing us to deliver valuations with pin-point accuracy across all asset types.

Glass’s Guide, with decades of history in the automotive market, is well known as one of the original “book” valuation providers. While it has been a trusted reference point for many years, its methods rely heavily on editorial judgment and historic datasets. This approach can’t compete with the real-time, AI-powered valuations Brego provides.

Accuracy That Speaks for Itself

Glass’s Guide has long served the industry, but its traditional approach means valuations can often lag behind real market conditions. Editorial inputs and auction data can be valuable, but they lack the scale and precision of true machine learning.

By contrast, Brego’s AI valuations achieve over 93% accuracy within 10% of the actual market value, based on live testing against market transactions. Our system continuously updates from millions of daily data points — meaning valuations stay aligned with the current retail market, not just historic averages.

Methodology: Glass’s Guide vs Brego

Glass’s Guide

• Relies on a combination of editorial expertise and auction data.
• Values are often based on historic sales records, which can be several weeks or months out of date.
• Editorial teams apply judgement to fill gaps in data coverage, but this introduces subjectivity.
• Strong on traditional categories like cars and vans, but limited when it comes to emerging or niche assets.

Brego

• Uses advanced deep-learning neural networks trained on billions of live and historic data points.
• Models ingest real-time retail listings, trade data, and market signals every day.
• Valuations are produced algorithmically, without editorial bias or manual adjustments.
• Coverage extends beyond cars into vans, bikes, caravans, campervans, and static holiday homes — with the same high accuracy.
• Every valuation is consistent, repeatable, and backed by a transparent AI methodology.

In summary, Glass’s Guide applies human-led judgement to historic data, while Brego harnesses AI and real-time data for valuations that reflect today’s market conditions.

Valuing More Than Just Cars

Glass’s Guide is now primarily focused on cars, vans, and standard automotive categories; following them pulling out of the leisure asset space. At Brego, our coverage goes much further:

1. Cars
2. Vans
3. Motorbikes
4. Caravans
5. Campervans
6. Static holiday homes
7. HGVs (Heavy Goods vehicles)
8. Agricultural vehicles

This breadth makes Brego the only provider capable of giving reliable valuations across the widest range of leisure and automotive assets.

Platform Analytics and Tools

Glass’s Guide remains a respected industry name, offering standardised pricing references and editorial valuations. This still benefits businesses that want a familiar, traditional valuation model. But with its reliance on historical auction data, values can often undershoot actual retail prices — and without full historical data on niche assets, coverage can be limited.

Brego, on the other hand, delivers a comprehensive AI-driven platform that no other provider matches:

• Accurate valuations using cutting-edge AI
• Advanced market analytics from millions of live data points
• Stock sourcing and B2B trading through the Brego Marketplace
• Stock management tools for dealerships
• Book valuations for insurers and lenders
• Dealership performance analytics
• Historical valuations on any date and time
• Enterprise-grade features (SSO, dashboards, custom applications)
• BregoCheck – vehicle history and provenance checks
• Integrated DVLA and SMMT data
• Downloadable reports
• Full-featured API with the fastest response times in the industry

The Bottom Line

Glass’s Guide has heritage and name recognition in the automotive industry — but when it comes to accuracy, breadth, and modern analytics, it falls behind what’s possible with today’s AI technology.

Brego offers a future-proof solution: valuations across more asset types, real-time accuracy powered by billions of data points, and a platform of dealer, lender, and insurer tools that Glass’s Guide simply can’t match.
