How it works·The methodology
Most valuation tools won’t tell you their sample size or their accuracy. We publish both, and the per-make breakdown.
465,000+ live observations across UK car marketplaces — refreshed every 23 hours. Not a stale book price.
1,232 make/model/year groups validated against ground-truth AutoTrader Trade Portal retail values. We know where the gaps are by brand.
78.1% within ±15%. 6.0% median error. We tell you which brands we nail (Porsche 93%) and where we slip (Vauxhall 29%). Transparency is the moat.
ScanAuctions runs on its own engine. No £500–£1,500/month AutoTrader Trade Portal needed. If you have AT, we cross-reference both.
Enter a UK reg. We pull make, model, year, engine and fuel from DVLA, then run the valuation. You only add mileage.
Volkswagens list 16% below retail. Porsches list 2.6% above. The engine applies per-make multipliers so you get the truth, not the asking price.
Benchmark results·2,617 cars tested
