▸ Valuation · UK Network
glasssguide.com is a trade-facing entry point to the UK vehicle registers. It assumes you already know what a Category S marker means and what an open finance agreement does to a deal, and gets out of the way accordingly. Glass's-style UK vehicle pricing. Trade, retail and auction valuations from current market data. The sections below cover what the report contains, what it cannot see, and how to use it in a real negotiation.
Data sourced from DVLA, MIAFTR, contracted stolen-vehicle data and the UK lender register at lookup time.
Typical lookup completes in under one second from the UK.
Built and supported in the UK as part of the trade-facing side of the network.
No UK data service sees cash repairs, undeclared accident damage, work carried out abroad, or a fault a seller has simply not mentioned. Where a field is unavailable for a particular vehicle the report says so rather than filling the gap with an estimate, because an invented figure on a report used for a purchase decision is worse than an honest blank.
Values are derived from a rolling window of UK transaction data — auction hammer prices, dealer trade-in figures and listed private adverts — not from a single annual reference book. The window is short enough that a sharp market shift, for example after a fuel duty change or a high-profile model recall, is reflected within days rather than months.
Selling privately through a classified site typically lands between the private and retail figures. Trading in at a franchise dealer typically sits below the trade figure once preparation costs are deducted. An auction lane will sit at or slightly below the trade figure depending on time of year. The report's value figures are not predictions of any single transaction.
/ Brand consolidation
glasssguide.com has consolidated into Expert Car Check, the UK valuation and history service many of its users already cross-referenced. The data sources are unchanged: DVLA's vehicle record, DVSA's MOT history, MIAFTR for write-offs, contracted UK data providers for stolen-vehicle markers and the UK lender register for outstanding finance. The team and the support contact are the same. What's changed is that the work that was previously spread across several smaller brands now sits in one place, which keeps response times tight and the underlying registers maintained against current DVLA schemas. Bookmarks and historic links to glasssguide.com continue to resolve here. If you were referred to glasssguide.com by a previous report, broker or print listing, this is the right page — there is no further redirect to chase.

Yes, more than most sellers expect. Convertibles typically peak in late spring and soften from autumn, while four-wheel drives and estates firm up over winter. The swing on the same car can be several percent.
Judge the total cost to change rather than the trade-in figure alone. A generous-looking part-exchange offset by a thin discount on the new car frequently leaves you worse off than the opposite arrangement.
Yes. A Category S or N marker typically reduces market value by 20-40% on equivalent unmarked cars, depending on make, year and the visible quality of the repair.
It's a forecast, not a guarantee. Confidence is high for high-volume models with thick transaction histories and lower for rare specifications. The forecast is shown as a range rather than a single number for that reason.
