Valuation — A field study
glassguidevalue.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 guide-style UK car valuations. Know what dealers, auctions and forecourts really pay. What follows is the detail behind the lookup — sources, limits and the questions worth asking the seller.
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.
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.
A clean check confirms that, at the moment of lookup, no UK insurer has filed a total-loss marker, no lender has registered an open agreement and no police force has reported the vehicle stolen. It does not confirm mechanical condition, repair quality, or work carried out in cash and never declared to an insurer. Treat the report as the legal and financial backstop to an in-person inspection, not a replacement for one.
/ Brand consolidation
glassguidevalue.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 glassguidevalue.com continue to resolve here. If you were referred to glassguidevalue.com by a previous report, broker or print listing, this is the right page — there is no further redirect to chase.

No. Comparable transaction data is sparse for classics and the standard model under-reports value. The report flags such vehicles and recommends a specialist valuer's opinion as the primary figure.
That is negative equity, and the shortfall has to be settled in cash or carried into the next agreement. Comparing your settlement letter against the valuation before committing is the most useful check near the end of a PCP term.
No. Private sale typically lands between private and retail. Trade value is the floor a dealer would offer, not the ceiling a private buyer would pay.
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.
