How it works·The methodology
Not a black box.
A measurable one.
Most valuation tools won’t tell you their sample size or their accuracy. We publish both, and the per-make breakdown.
Real UK market data
1,000,000+ live observations across UK car marketplaces — refreshed every 23 hours. Not a stale book price.
AutoTrader cross-reference
1,232 make/model/year groups benchmarked against AutoTrader Trade Portal retail values. We know where the gaps are by brand.
Published accuracy
91% within 15%, 81% within 10%. 3.8% median error. We publish the per-make breakdown so you can see exactly where we're strongest.
No AT subscription required
ScanAuctions runs on its own engine. No £500–£1,500/month AutoTrader Trade Portal needed. If you have AT, we cross-reference both.
VRM lookup
Enter a UK reg. We pull make, model, year, engine and fuel from DVLA, then run the valuation. You only add mileage.
Brand-by-brand pricing
Volkswagens list 16% below retail. Porsches list 2.6% above. We correct each brand's gap so you get the real trade value, not the asking price.
