Know what
it’s really worth.

Benchmarked against AutoTrader Trade Portal retail values (500-car sample, June 2026): 91% within 15%, 81% within 10%, median error 3.8%. The methodology section below shows exactly how it works — and where we're still improving.

No. Our valuations are built on 1,000,000+ live prices tracked across UK car marketplaces. We don't need AutoTrader Trade Portal access to value a car. If you do have AutoTrader, we check both for extra confidence.

Yes, completely free for individual valuations — no card needed, just a free account. Bulk valuations (CSV upload), PDF reports, MOT history, and the Motorway + CarWow scanner come with our paid ScanAuctions plans (Basic £129/mo, Ultimate £249/mo). A single car valuation will always be free.

Make, model, year, mileage, fuel type, gearbox and trim. We compare your car against 1,000,000+ live UK listings (refreshed every 23 hours) and 1,232 make/model/year groups checked against AutoTrader Trade Portal retail values. Brand-by-brand adjustments correct for the gap between asking prices and what cars actually sell for.

Yes. Enter the reg and we pull make, model, year, engine and fuel from DVLA, then run the valuation. You only need to add mileage. Available in the full tool — paid plans only.

Public listings show asking prices (what sellers want); the AutoTrader Trade Portal shows retail values (what cars actually sell at). Across 1,232 make/model/year groups we measure an average 5.6% gap — but it's not uniform. Volkswagens list 16% below retail; Porsches list 2.6% above. We correct for this brand by brand.
