The valuation engine behind MarketCheck Price™
Send a VRM, current mileage, dealer type and postcode; get back the predicted market value in pounds. The model is trained on over 1 million recently sold listings from 15,000+ dealerships and retrains weekly, so it tracks the market rather than lagging it.
The premium tier adds the evidence: comparable listings with their prices, mileages and locations, plus statistics from minimum to percentiles, so every valuation can be justified to a customer, an underwriter or an auditor.

FAQ
Common questions
What does the model need to price a car?
Four inputs: the number plate, current mileage, whether it is being sold by a franchise or independent dealer, and a postcode. The model handles the rest, from spec to regional demand.
How accurate is it?
Measured on cars the model has never seen: a 93%+ R² score overall, with 90% of predictions within 10% of the real price for vehicles under 10 years old and 80% within 25% for older vehicles.
How does it stay current?
The model retrains every week on over 1 million recently sold listings from 15,000+ dealerships, so a moving market shows up in the price within days, not quarters.
Can I justify the price to a customer or auditor?
Yes, that is what the premium tier is for: every prediction can return its comparable listings and full statistics, from minimum to percentiles, as the audit trail behind the number.
